1 Version 1.0.3 2 * Added support for enabling/disabling large stack optimisations, used in 3 halfFunction.h. 4 (Piotr Stanczyk) 5 * Added ImathNoise.(h/cpp) files. Initializes Perlin noise to match the 6 Renderman implmenetation. 7 (Pixar Contribution) 8 * Fixed a number of missing includes to comply with stricter 9 enforcement by gnu compilers. 10 (Piotr Stanczyk) 11 * Depracated compiler flag: -Wno-long-double since it is no longer 12 supported under OS X. 13 (Piotr Stanczyk) 14 * A minor API change to Imath::Frustum has been made: the functions 15 'near' and 'far' have been renamed to 'nearPlane' and 'farPlane' due 16 to conflicts with certain windows headers. The former alternate 17 accessor names for these values on windows ('hither' and 'yon') 18 remain, though should be considered deprecated. 19 (David Lenihan) 20 * Added SVD, eigenvalue solver, and procrustes fit calculations 21 to ImathMatrixAlgo. 22 (Chris Twigg, Ji Hun Yu) 23 * Added Imath::FrustumTest for frustum visibility testing. 24 (Eric Johnston) 25 * Fixed a stack corruption in the matrix minorOf functions. 26 (Nick Rasmussen) 27 * Visual studio 2008 project files have been added to the vc/vc9 28 directory, and several minor visual studio compile fixes have 29 been applied. 30 (Nick Rasmussen) 31 * Updated the so verison to 7. 32 (Piotr Stanczyk) 33 * Depracated the MacCode_Warrior and Shake submodules. 34 (Piotr Stanczyk) 35 36 Version 1.0.2 37 * Added support for targetting builds on 64bit Windows and minimising 38 number of compiler warnings on Windows. Thanks to Ger Hobbelt for his 39 contributions to CreateDLL. 40 (Ji Hun Yu) 41 * Removed a spurious restrict qualifier in the matrix manipulation code 42 that was causing the 64-bit MS compiler to generate code in release 43 mode that caused incorrect results. 44 (Ji Hun Yu) 45 * Added patches for improving universal binaries on OS X. Thanks to 46 Paul Schneider for the contribution 47 (Piotr Stanczyk) 48 * Imath::Box optimization: remove loops from methods by partially 49 specializing the class, for boxes of two and three dimensions. 50 (Piotr Stanczyk) 51 * Added explicit copy constructors to Imath::Matrix33<T> and 52 ImathMatrix44<T> to make conversions between float and double 53 matrices more convenient. 54 (Florian Kainz) 55 * Added slerpShortestArc() and euclideanInnerProduct() functions 56 to Imath::Quat<T>. 57 (Nick Porcino) 58 * Added 4D vector class template Imath::Vec4<T>. 59 (Nick Porcino) 60 * Copy constructors and assignment operators for Matrix33<T> 61 and Matrix44<T> are up to 25% faster. Added matrix constructors 62 that do not initialize the matrix (this is faster in cases where 63 the initial value of the matrix is immediately overwritten anyway). 64 (Nick Porcino) 65 * Rewrote function closestPointOnBox(point,box). Shortened 66 the code, improved numerical accuracy, fixed a bug where 67 closestPointOnBox(box.center(),box) would return the center 68 of the +Z side of the box, even if the +/-X or +/-Y sides 69 were closer. 70 (Florian Kainz) 71 * Rewrote function findEntryAndExitPoints() in ImathBoxAlgo.h. 72 Results are now consistent with those from intersect(), also 73 in ImathBoxAlgo.h. 74 (Florian Kainz) 75 * Made Vec2<T>::length() and Vec3<T>::length() more accurate for 76 vectors whose length is less than sqrt(limits<T>::smallest()); 77 (Florian Kainz) 78 * Made Quat<T>::angle() more accurate for small angles. 79 (Don Hatch) 80 81 Version 1.0.1: 82 * Removed Windows .suo files from distribution. 83 (Eric Wimmer) 84 85 Version 1.0.0: 86 * Bumped DSO version number to 6.0 87 (Florian Kainz) 88 * Rounding during float-to-half conversion now implements 89 "round to nearest even" mode: if the original float value 90 is exactly in the middle between the two closest half values 91 then rounding chooses the half value whose least significant 92 bit is zero. 93 (Florian Kainz) 94 * Installation Tuning: 95 - Corrected version number on dso's (libtool) - now 5.0 96 - Separated ILMBASE_LDFLAGS and ILMBASE_LIBS so that test programs 97 in configure scripts of packages dependent on IlmBase can link 98 with static libraries properly 99 - eliminated some warning messages during install 100 (Andrew Kunz) 101 102 Version 0.9.0: 103 * Initial release of this code as a separate library. 104 Previously the libraries contained were part of 105 version 1.4.0 of OpenEXR 106 * New build scripts for Linux/Unix 107 (Andrew Kunz) 108 * New Windows project files and build scripts 109 (Kimball Thurston) 110
