Defines HAVE_POSIX_SEMAPHORES if found. dnl dnl This macro figures out how to build C programs using POSIX threads. dnl It sets the PTHREAD_LIBS output variable to the threads library and dnl linker flags, and the PTHREAD_CFLAGS output variable to any special dnl C compiler flags that are needed. (The user can also force certain dnl compiler flags/libs to be tested by setting these environment dnl variables.) dnl dnl Also sets PTHREAD_CC to any special C compiler that is needed for dnl multi-threaded programs (defaults to the value of CC otherwise). dnl (This is necessary on AIX to use the special cc_r compiler alias.) dnl dnl NOTE: You are assumed to not only compile your program with these dnl flags, but also link it with them as well. e.g. you should link dnl with $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS dnl $LIBS dnl dnl If you are only building threads programs, you may wish to use dnl these variables in your default LIBS, CFLAGS, and CC: dnl dnl LIBS="$PTHREAD_LIBS $LIBS" dnl CFLAGS="$CFLAGS $PTHREAD_CFLAGS" dnl CC="$PTHREAD_CC" dnl dnl In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute dnl constant has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to dnl that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX). dnl dnl ACTION-IF-FOUND is a list of shell commands to run if a threads dnl library is found, and ACTION-IF-NOT-FOUND is a list of commands to dnl run it if it is not found. If ACTION-IF-FOUND is not specified, the dnl default action will define HAVE_PTHREAD. dnl dnl Please let the authors know if this macro fails on any platform, or dnl if you have any other suggestions or comments. This macro was based dnl on work by SGJ on autoconf scripts for FFTW (www.fftw.org) (with dnl help from M. Frigo), as well as ac_pthread and hb_pthread macros dnl posted by Alejandro Forero Cuervo to the autoconf macro repository. dnl We are also grateful for the helpful feedback of numerous users. dnl dnl @category InstalledPackages dnl @author Steven G.

IlmThread is a thread abstraction library for use with OpenEXR and other software packages. It currently supports pthreads and Windows threads. Imath implements 2D and 3D vectors, 3x3 and 4x4 matrices, quaternions and other useful 2D and 3D math functions. Iex is an exception-handling library. If you have questions about using the IlmBase libraries, you may want to join our developer mailing list. See http://www.openexr.com for details. LICENSE ------- The IlmBase source code distribution is free software. See the file named COPYING (included in this distribution) for details. BUILDING ILMBASE ---------------- To build IlmBase on GNU/Linux or other UNIX-like systems, do this: ./configure make make install unless you obtained IlmBase directly from CVS, in which case you should first read README.CVS. See README.OSX for details on building IlmBase in MacOS X. Do `make check` to run the IlmBase confidence tests. They should all pass; if you find a test that does not pass on your system, please let us know. Other UNIX variants haven't been tested, but should be easy to build. Let us know if you're having problems porting IlmBase to a particular platform. All include files needed to use the IlmBase libraries are installed in the OpenEXR subdirectory of the install prefix, e.g. /usr/local/include/OpenEXR. USING ILMBASE IN YOUR APPLICATIONS ---------------------------------- On systems with support for pkg-config, use `pkg-config --cflags IlmBase` for the C++ flags required to compile against IlmBase headers; and `pkg-config --libs IlmBase` for the linker flags required to link against IlmBase libraries. ilmbase-1.0.1/configure.ac0000664001405300000670000000747010702770752012355 00000000000000dnl Process this file with autoconf to produce a configure script.

This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir.

(Eric Wimmer) Version 1.0.0: * Bumped DSO version number to 6.0 (Florian Kainz) * Rounding during float-to-half conversion now implements "round to nearest even" mode: if the original float value is exactly in the middle between the two closest half values then rounding chooses the half value whose least significant bit is zero. (Florian Kainz) * Installation Tuning: - Corrected version number on dso's (libtool) - now 5.0 - Separated ILMBASE_LDFLAGS and ILMBASE_LIBS so that test programs in configure scripts of packages dependent on IlmBase can link with static libraries properly - eliminated some warning messages during install (Andrew Kunz) Version 0.9.0: * Initial release of this code as a separate library. Previously the libraries contained were part of version 1.4.0 of OpenEXR * New build scripts for Linux/Unix (Andrew Kunz) * New Windows project files and build scripts (Kimball Thurston) ilmbase-1.0.1/INSTALL0000664001405300000670000000011310540102371011065 00000000000000See the README file for instructions on how to build IlmBase from source. ilmbase-1.0.1/NEWS0000664001405300000670000000004610540613233010544 00000000000000Version 0.9.0: - Initial release ilmbase-1.0.1/config.guess0000755001405300000670000012542210540627204012374 00000000000000#! /bin/sh # Attempt to guess a canonical system name. # Copyright (C) 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, # 2000, 2001, 2002, 2003, 2004, 2005 Free Software Foundation, Inc. timestamp='2005-02-10' # This file is free software; you can redistribute it and/or modify it # under the terms of the GNU General Public License as published by # the Free Software Foundation; either version 2 of the License, or # (at your option) any later version. # # This program is distributed in the hope that it will be useful, but # WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

It's a good idea to run this whenever you update IlmBase from CVS. Then run './configure' and make. Note that the configure.ac file requires a fairly new version of automake. If you get this error message: running aclocal ... aclocal: configure.ac: 142: macro `AM_CFLAGS' not found in library aclocal: configure.ac: 143: macro `AM_CXXFLAGS' not found in library failed! you should upgrade your automake to version 1.6 or better. ilmbase-1.0.1/README.OSX0000664001405300000670000000152410540613207011400 00000000000000IlmBase on MacOS X ------------------ Building IlmBase on MacOS X is just like building it on GNU/Linux. Follow the instructions in the README file under BUILDLING ILMBASE, but see below re: shared libraries. On OS X 10.4, you can build universal binaries by passing '--enable-osx-universal-binaries --disable-dependency-tracking' to the configure script. The default is *not* to build universal binaries. Shared libraries ---------------- IlmBase requires the "flat namespace" option when built as a shared library. You may have problems trying to use IlmBase shared libraries with applications that expect OS X's two-level namespace. We have not tested the shared libs extensively, though they appear to work with exrdisplay and exrheader, but use them at your own risk. We will support two-level namespace shared libs in a future release. ilmbase-1.0.1/README.win320000664001405300000670000001644510654552764011721 00000000000000IlmBase is one of five software packages that were designed to work together: IlmBase, OpenEXR, OpenEXR_Viewers, CTL and OpenEXR_CTL. You may want to build Imath by itself, or together with one or more of the other packages. What follows are instructions for building all five packages. If you want to build only IlmBase, stop after step 1. A couple of notes before getting started: - This is not the only way to do this. This document describes a path that doesn't involve installing libraries into default system paths, but rather, creates a standalone universe. - Some of these steps may be a bit redundant, and will be optimized in the future. - The Debug versions of the libraries and tools are not required if you are not going to be doing any debugging, and can be optionally built. The source will build under both Visual Studio versions 7 and 8, and there are separate directories for the corresponding build files. The tag is used in this document to describe the appropriate folder in the path that corresponds to your the version of Visual Studio. The Visual Studio project files assume, and help build out, a directory called "Deploy". In the end, this directory will contain the objects that might then be moved away from the source for general running of the compiled programs. The directory structure at the end of compiling all the related tools looks like this: Deploy include lib Debug Release bin Debug Release openexr-cvs (name as desired) IlmBase OpenEXR OpenEXR_Viewers ctl-cvs (name as desired) CTL OpenEXR_CTL fltk FL GL lib nvidia include GL glh lib If OpenEXR_Viewers is not being compiled, then fltk and nvidia will not be needed, but that will be covered later. Step 1. Compile IlmBase a. Point Visual Studio at the .sln file in vc\\IlmBase in the IlmBase subdirectory b. Select the Release configuration and hit Build Solution. This will create the Deploy directory, and copy the relevant parts to it. c. If the debug versions are desired, select the Debug configuration and hit Build Solution. This will add the Debug directories to Deploy. Step 2. Compile OpenEXR support a. Retrieve the zlib binaries. The project files are set up to link against the dll version of zlib, but can easily be changed to link against a static version, or a self-built version if desired. 1. Go to http://www.zlib.net and download the precompiled DLL version of zlib (as of writing, zlib123-dll.zip) 2. If you don't wish to put the files into your MS visual studio directories and install the dll into windows\system32: a. Put a copy of zlib1.dll into Deploy\bin\Release and Deploy\bin\Debug b. Copy the header files into Deploy\include c. Copy zdll.lib and zdll.exp into Deploy\lib\Release and Deploy\lib\Debug b. Open the Visual Studio project in OpenEXR\vc\\OpenEXR. c. Select the Release configuration and build. The IlmImfTest program runs a confidence test of your build to make sure it is able to work, and may take some time to complete. d. Optionally select the Debug configuration and build. Step 3. Compile CTL support a. Open the Visual Studio project in CTL\vc\\CTL. b. Select the Release configuration and build. The IlmCtlTest program runs a confidence test of your build to make sure it is able to work, and may take some time to complete. c. Optionally select the Debug configuration and build. Step 4. Compile OpenEXR_CTL support a. Open the Visual Studio project in OpenEXR_CTL\vc\\OpenEXR_CTL. b. Select the Release configuration and build. c. Optionally select the Debug configuration and build. Step 5. Compile OpenEXR_Viewers a. Open the appropriate Visual Studio project in OpenEXR_Viewers\vc\\OpenEXR_Viewers depending on whether or not you want CTL support. b. exrdisplay requires fltk to work. 1. Go to http://www.fltk.org and download fltk 1.1.7 2. Open its project files and compile using the instructions they provide. 3. Create the fltk directory at the top level of your directory structure as presented above and copy the FL, GL, and lib folders into the fltk directory 4. exrdisplay links fltk statically, so no dll is needed. c. playexr requires the nvidia cg library as well as glut and glew. 1. Setup the cg toolkit a. Go to http://developer.nvidia.com, the developer section and download the cg toolkit, version 1.5, and install it. The path where you choose to install Cg is referred to by the tag in the steps below. b. During the installation, if the integrate with visual studio option is selected, the header files will be automatically found. Otherwise, copy the directory \Cg\include\Cg to Deploy\include\Cg b. Copy the cg.dll and cgGL.dll from the \Cg\bin into Deploy\bin\Release and Deploy\bin\Debug, or otherwise make them available (put them in system32, add to path, etc.) c. Copy the cg.lib and cgGL.lib from \Cg\lib into Deploy\lib\Release and Deploy\lib\Debug 2. Make glut available. This can be done via several mechanisms. See step 4 below. 3. Make glew available. This can be done via several mechanisms. http://glew.sourceforge.net is the master site for this library. See step 4 below. 4. nVidia makes both glut and glew available in their SDK package, which is a fairly large download, but provides a wealth of other information on programming for the GPU, and is generally a useful package, so that is the path chosen for this set up. a. Go to http://developer.nvidia.com and download version 10 of the SDK and install it. It will prompt you to install the Cg toolkit, but this is not necessary as it was handled in step 1. The path where you choose to install the SDK is referred to by the tag in the steps below. b. Make an nvidia folder at the top level, with an include and lib folder inside it. Inside the lib folder, make Debug and Release folders. c. Copy the \external\include\GL directory into nvidia\include the GL and glh folders into nvidia\include. d. Copy the glew headers in \common\GLEW\include\GL into nvidia\include\GL. e. Copy \common\GLEW\lib\glew32.lib and \external\lib\glut32.lib into Deploy\bin\Release. f. Copy bin\glut32.dll and bin\glew32.dll into Deploy\bin\Release. d. Build the Release configuration of the OpenEXR_Viewers. e. Build the Debug configuration if desired. At this point, the Deploy folder should be fully built out and ready to be used. Both exrdisplay and playexr are meant to be launched from the command line, as they originated as unix commands, so open a command prompt, cd to the Deploy\bin\Release folder and enjoy. ilmbase-1.0.1/bootstrap0000775001405300000670000000257410540077012012017 00000000000000#! /bin/sh # If we're on OS X, use glibtoolize instead of toolize HOSTTYPE=`uname` if [ "$HOSTTYPE" == "Darwin" ]; then LIBTOOLIZE=glibtoolize else LIBTOOLIZE=libtoolize fi # Check Autoconf version if [ -x `which autoconf` ]; then AC_VER=`autoconf --version | head -n 1 | sed 's/^[^0-9]*//'` AC_VER_MAJOR=`echo $AC_VER | cut -f1 -d'.'` AC_VER_MINOR=`echo $AC_VER | cut -f2 -d'.' | sed 's/[^0-9]*$//'` if [ "$AC_VER_MAJOR" -lt "2" ]; then echo "Autoconf 2.13 or greater needed to build configure." exit 1 fi if [ "$AC_VER_MINOR" -lt "13" ]; then echo "Autoconf 2.13 or greater needed to build configure." exit 1 fi if [ "$AC_VER_MINOR" -lt "50" ]; then if [ ! -e configure.in ]; then ln -s configure.ac configure.in fi echo "If you see some warnings about cross-compiling, don't worry; this is normal." else rm -f configure.in fi else echo autoconf not found.

The class // inherits from Vec3 to it can be freely cast. The additional // information is the euler priorities rep. This class is // essentially a rip off of Ken Shoemake's GemsIV code. It has // been modified minimally to make it more understandable, but // hardly enough to make it easy to grok completely. // // There are 24 possible combonations of Euler angle // representations of which 12 are common in CG and you will // probably only use 6 of these which in this scheme are the // non-relative-non-repeating types. // // The representations can be partitioned according to two // criteria: // // 1) Are the angles measured relative to a set of fixed axis // or relative to each other (the latter being what happens // when rotation matrices are multiplied together and is // almost ubiquitous in the cg community) // // 2) Is one of the rotations repeated (ala XYX rotation) // // When you construct a given representation from scratch you // must order the angles according to their priorities. So, the // easiest is a softimage or aerospace (yaw/pitch/roll) ordering // of ZYX. // // float x_rot = 1; // float y_rot = 2; // float z_rot = 3; // // Eulerf angles(z_rot, y_rot, x_rot, Eulerf::ZYX); // -or- // Eulerf angles( V3f(z_rot,y_rot,z_rot), Eulerf::ZYX ); // // If instead, the order was YXZ for instance you would have to // do this: // // float x_rot = 1; // float y_rot = 2; // float z_rot = 3; // // Eulerf angles(y_rot, x_rot, z_rot, Eulerf::YXZ); // -or- // Eulerf angles( V3f(y_rot,x_rot,z_rot), Eulerf::YXZ ); // // Notice how the order you put the angles into the three slots // should correspond to the enum (YXZ) ordering. The input angle // vector is called the "ijk" vector -- not an "xyz" vector. The // ijk vector order is the same as the enum. If you treat the // Euler<> as a Vec<> (which it inherts from) you will find the // angles are ordered in the same way, i.e.: // // V3f v = angles; // // v.x == y_rot, v.y == x_rot, v.z == z_rot // // If you just want the x, y, and z angles stored in a vector in // that order, you can do this: // // V3f v = angles.toXYZVector() // // v.x == x_rot, v.y == y_rot, v.z == z_rot // // If you want to set the Euler with an XYZVector use the // optional layout argument: // // Eulerf angles(x_rot, y_rot, z_rot, // Eulerf::YXZ, // Eulerf::XYZLayout); // // This is the same as: // // Eulerf angles(y_rot, x_rot, z_rot, Eulerf::YXZ); // // Note that this won't do anything intelligent if you have a // repeated axis in the euler angles (e.g. XYX) // // If you need to use the "relative" versions of these, you will // need to use the "r" enums. // // The units of the rotation angles are assumed to be radians. // //---------------------------------------------------------------------- #include "ImathMath.h" #include "ImathVec.h" #include "ImathQuat.h" #include "ImathMatrix.h" #include "ImathLimits.h" #include namespace Imath { #if (defined _WIN32 || defined _WIN64) && defined _MSC_VER // Disable MS VC++ warnings about conversion from double to float #pragma warning(disable:4244) #endif template class Euler : public Vec3 { public: using Vec3::x; using Vec3::y; using Vec3::z; enum Order { // // All 24 possible orderings // XYZ = 0x0101, // "usual" orderings XZY = 0x0001, YZX = 0x1101, YXZ = 0x1001, ZXY = 0x2101, ZYX = 0x2001, XZX = 0x0011, // first axis repeated XYX = 0x0111, YXY = 0x1011, YZY = 0x1111, ZYZ = 0x2011, ZXZ = 0x2111, XYZr = 0x2000, // relative orderings -- not common XZYr = 0x2100, YZXr = 0x1000, YXZr = 0x1100, ZXYr = 0x0000, ZYXr = 0x0100, XZXr = 0x2110, // relative first axis repeated XYXr = 0x2010, YXYr = 0x1110, YZYr = 0x1010, ZYZr = 0x0110, ZXZr = 0x0010, // |||| // VVVV // Legend: ABCD // A -> Initial Axis (0==x, 1==y, 2==z) // B -> Parity Even (1==true) // C -> Initial Repeated (1==true) // D -> Frame Static (1==true) // Legal = XYZ | XZY | YZX | YXZ | ZXY | ZYX | XZX | XYX | YXY | YZY | ZYZ | ZXZ | XYZr| XZYr| YZXr| YXZr| ZXYr| ZYXr| XZXr| XYXr| YXYr| YZYr| ZYZr| ZXZr, Min = 0x0000, Max = 0x2111, Default = XYZ }; enum Axis { X = 0, Y = 1, Z = 2 }; enum InputLayout { XYZLayout, IJKLayout }; //---------------------------------------------------------------- // Constructors -- all default to ZYX non-relative ala softimage // (where there is no argument to specify it) //---------------------------------------------------------------- Euler(); Euler(const Euler&); Euler(Order p); Euler(const Vec3 &v, Order o = Default, InputLayout l = IJKLayout); Euler(T i, T j, T k, Order o = Default, InputLayout l = IJKLayout); Euler(const Euler &euler, Order newp); Euler(const Matrix33 &, Order o = Default); Euler(const Matrix44 &, Order o = Default); //--------------------------------- // Algebraic functions/ Operators //--------------------------------- const Euler& operator= (const Euler&); const Euler& operator= (const Vec3&); //-------------------------------------------------------- // Set the euler value // This does NOT convert the angles, but setXYZVector() // does reorder the input vector. //-------------------------------------------------------- static bool legal(Order); void setXYZVector(const Vec3 &); Order order() const; void setOrder(Order); void set(Axis initial, bool relative, bool parityEven, bool firstRepeats); //--------------------------------------------------------- // Conversions, toXYZVector() reorders the angles so that // the X rotation comes first, followed by the Y and Z // in cases like XYX ordering, the repeated angle will be // in the "z" component //--------------------------------------------------------- void extract(const Matrix33&); void extract(const Matrix44&); void extract(const Quat&); Matrix33 toMatrix33() const; Matrix44 toMatrix44() const; Quat toQuat() const; Vec3 toXYZVector() const; //--------------------------------------------------- // Use this function to unpack angles from ijk form //--------------------------------------------------- void angleOrder(int &i, int &j, int &k) const; //--------------------------------------------------- // Use this function to determine mapping from xyz to ijk // - reshuffles the xyz to match the order //--------------------------------------------------- void angleMapping(int &i, int &j, int &k) const; //---------------------------------------------------------------------- // // Utility methods for getting continuous rotations.

Makes a DLL have the same link semantics as a *nix DSO. Eliminates the need to declspec everything. This program also successfully exports templated objects, and all STL objects. ------------------------------------------------------------------------------- No warranty expressed or implied, supplied as is including all faults! ------------------------------------------------------------------------------- You must have already created a DLL using MSVC. Specify the MAP option when you build the DLL. This program reads in MAP file generated by your iinitial link, parses all the symbols, prepares a DEF file with the mangled symbols sniffs for required OBJS and LIBS creates a linker response file relinks your DLL using the new DEF file you must set up an environment variable called MSVCLINK which is the full path to the MSVC linker. eg: C:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\bin\link.exe If you have a BOOST_ROOT environment variable, CreateDLL will automatically include BOOST_ROOT\stage\lib in the link path. the arguments for CreateDLL are- full path to the .map file. full path to the place where you keep all your libs that you will link against. name of the generated import library. Typically it will be the same as the dll, eg Imath.dll + Imath.lib. However, if the library you're working on has a DLL version, and a static lib version, you will probably want to distinguish the name of the import library like this: ImathDLL.lib, or similar, so that there is no confusion about what the lib actually is. Use quotes if there are spaces. Otherwise, quotes are optional. Example CreateDLL "C:\coding\vc7\Dev\Ae\Ae.map" "C:\coding\objects" "C:\coding\objects\Ae.lib" objects is the place where all the .libs have been copied to. If you have a lot of third party bits, eg., jpeg.lib, copy them there too. Now your DLL has all its symbols exported! The new DLL will overwrite the original DLL in place. ------------------------------------------------------------------------------- Extra Magic: template instantiation You may need some extra magic to export some templates. If you get a link error that indicates that a templated class is not found - Let's say you have templated class Foo, specialized on int, and Foo is needed to link your DLL. You will need a preprocessor definition such as MYMODULE_EXPORTS which indicates that your module is being use. Please be aware that the old schtick of a DLL_EXPORT is not sufficient if you have more than one DLL in play. Use this method instead. #ifdef MSC_VER #ifndef MYMODULE_EXPORTS extern template class Foo; #endif #endif This generates a warning, but it is the microsoft sanctioned solution to this problem. In Foo.cpp you must also #ifdef MSC_VER template class Foo; #endif ------------------------------------------------------------------------------- Extra Magic: static member variables This program does not fix the problem that the MS dynamic loader can't resolve static member variables of classes properly. This issue will be the most important thing to watch out for. example - class Foo { public: static int bar; }; the dynamic loader puts bar in the wrong memory space. This is a fundamental problem with the architecture of DLL's. There is no workaround, except to change the code; example, in the header file - #ifdef MSC_VER extern __declspec(dllexport) int foo_bar; #endif and in the .cpp file, #ifdef MSC_VER __declspec(dllexport) int foo_bar; #endif You'll get multiple declarations of foo_bar, but the linker will resolve them down to one when the DLL is linked. ------------------------------------------------------------------------------- Extra Magic: exporting globals Finally, you'll still need to use declspecs for global variables. example - see static member variables example for foo_bar. ------------------------------------------------------------------------------- Extra Magic: vector deleting destructors If you REALLY need to use a vector deleting destructor, you'll need to declspec your class, and all the nested classes, in the traditional way. What's the issue? The linker strips all vector deleting destructors whether you want it to or not. declspecing the class provides a default implementation, as opposed to the you really want. This is a built-in hack in the linker dating back to VC5. The only workaround is to use STL vectors instead, or don't use vector deleting destructors at all. example - class Foo { public: ~Foo(int size) { } // linker will discard. it can't be done. };
