2 * Added support for enabling/disabling large stack optimisations, used in
5 * Added ImathNoise.(h/cpp) files. Initializes Perlin noise to match the
6 Renderman implmenetation.
8 * Fixed a number of missing includes to comply with stricter
9 enforcement by gnu compilers.
11 * Depracated compiler flag: -Wno-long-double since it is no longer
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.
20 * Added SVD, eigenvalue solver, and procrustes fit calculations
22 (Chris Twigg, Ji Hun Yu)
23 * Added Imath::FrustumTest for frustum visibility testing.
25 * Fixed a stack corruption in the matrix minorOf functions.
27 * Visual studio 2008 project files have been added to the vc/vc9
28 directory, and several minor visual studio compile fixes have
31 * Updated the so verison to 7.
33 * Depracated the MacCode_Warrior and Shake submodules.
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.
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.
45 * Added patches for improving universal binaries on OS X. Thanks to
46 Paul Schneider for the contribution
48 * Imath::Box optimization: remove loops from methods by partially
49 specializing the class, for boxes of two and three dimensions.
51 * Added explicit copy constructors to Imath::Matrix33<T> and
52 ImathMatrix44<T> to make conversions between float and double
53 matrices more convenient.
55 * Added slerpShortestArc() and euclideanInnerProduct() functions
58 * Added 4D vector class template Imath::Vec4<T>.
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).
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
71 * Rewrote function findEntryAndExitPoints() in ImathBoxAlgo.h.
72 Results are now consistent with those from intersect(), also
75 * Made Vec2<T>::length() and Vec3<T>::length() more accurate for
76 vectors whose length is less than sqrt(limits<T>::smallest());
78 * Made Quat<T>::angle() more accurate for small angles.
82 * Removed Windows .suo files from distribution.
86 * Bumped DSO version number to 6.0
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
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
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
108 * New Windows project files and build scripts
