NVIDIA Cg 2.2 February 2010 README Copyright (C) 2002-2010 NVIDIA Corp.
================================== This distribution contains -------------------------- - NVIDIA Cg toolkit documentation in the docs directory - NVIDIA Cg compiler (cgc) in the bin directory - NVIDIA Cg runtime libraries in the lib directory - Example Cg applications in the examples directory - Under Microsoft Windows, a Cg language syntax highlighter for Microsoft Visual Studio is provided in the msdev_syntax_highlighting directory - Under Microsoft Windows, if selected at install time, 64-bit binaries and libraries are in the bin.x64 and lib.x64 directories. See the release notes (docs/CgReleaseNotes.pdf) for detailed information about this release. The Cg toolkit is available for a number of different hardware and OS platforms. As of this writing, supported platforms include: - Microsoft NT 4, 2000, and Windows XP & Vista on IA32/x86/x86-64 (Intel, AMD) - Linux on IA32/x86 (Intel, AMD) - Linux for x64 (AMD64 and EMT64) - MacOS X 10.4 and 10.5 (Tiger and Leopard) - Solaris (x86/x86_64) Visit the NVIDIA Cg website at http://developer.nvidia.com/page/cg_main.html for updates and complete compatibility information. Changes since Cg 2.2 October 2009 --------------------------------- - Bug fixes - Require EXT_gpu_shader4 in GLSL when using bit shift/mask instructions - Modified example gs_simple to explicitly use the GLSL profiles if supported - HLSL semantic VFACE is now accepted as an alias for semantic FACE - Improved our handling of extensions on older versions of OpenGL - Various performance improvements - Enhanced cgfxcat to work for program files as well as effect files - Fixed some compiler crashes with malformed shaders - Fixed a crash in cgGetParameterBufferIndex and cgGetParameterBufferOffset - Fixed a bug in cgGetPassProgram for combined programs - Fixed a problem with geometry shaders on Solaris Changes since Cg 2.2 April 2009 ------------------------------- - New features - Allow compiler options in effect compile statements - e.g. VertexProgram = compile vp40 "-po PosInv=1" shader(); - Better performance when running on multicore CPUs - Choosing the "latest" profile is now deferred until effect validation - Now using MesaGLUT-7.5 for GLUT on Windows - Bug fixes - Improved the inverse matrix computation in cgGLSetStateMatrixParameter - Better memory behavior when a program is repeatedly recompiled - Fixed an issue when using PSIZE semantic with ps_3_0 and ps_4_0 profiles - cgCombinePrograms now works with CG_OBJECT programs - cgGetNextProgram was always returning 0 - Fixed a problem with effect parameters and cgGLGetTextureEnum - Allow comments prior to the shader version in D3D asm blocks of an effect - HLSL10: Mark globally scoped temporaries 'static' to keep them out of constant buffers - HLSL10: Allow any semantic for varyings provided the semantics match between stages - HLSL10: Fix handling of TEXUNITn semantic - HLSL10: Added support for arrays of samplers - HLSL10: Empty structs for uniform parameters crashed the D3D compiler - Fixed a problem when connecting parameters of type string - Corrected issues in the fp20 profile on Solaris Changes since Cg 2.2 beta February 2009 --------------------------------------- - New features - Support for pack_matrix() pragma - Arrays of shaders can now be used in CgFX files - Support for 64-bit Solaris - Bug fixes (see release notes for details) Changes since Cg 2.1 November 2008 ---------------------------------- - New features - DirectX10 and GLSL geometry profiles (gs_4_0 AND glslg) - Support for "latest" profile keyword in CgFX compile statements - Additional API routines (see release notes for a complete list) - Migrated the OpenGL examples onto GLEW - New examples - Direct3D10/advanced/combine_programs - Direct3D10/advanced/gs_shrinky - Direct3D10/advanced/gs_simple - OpenGL/advanced/cgfx_latest - Tools/cgfxcat - Tools/cginfo - New documentation - Updated reference manual for new profiles and entry points |
