I've posted NVIDIA Cg 1.5 beta2 headers for Delphi & FreePascal. In this release I've included seven simple Direct3D tutorials of Cg runtime usage.

<UL>What does new release adds?
<LI>OpenGL GLSL profiles</LI>
<LI>Direct3D9 SM3.0 profiles</LI>
<LI>Procedural API for Effect creation (COLLADA support)</LI>
<LI>Program combining for inter-program optimization</LI>
<LI>Rewrite of major portions of the Cg Runtime for enhanced performance</LI>
<LI>Cg 1.3 and 1.4 style Effects files supported</LI>
<LI>Cg 1.5 Beta 1 should be backward compatible with apps written against Cg 1.4.1.</LI>
<LI>Runtime now supports loading pre-compiled objects through runtime API (CG_OBJECT for cgCreateProgram)</LI>[/list]
New release of Cg became truly cross-platform product, covering: Win32, Win64, Linux (32-bit and 64-bit), MacOS 10.3 (Panther) and
10.4 (Tiger), Mac OS X: Universal or so-called "fat" binaries with both PowerPC and x86 code, Solaris x86. Anyone want to add OpenGL examples and check compatibility of FreePascal port on these additional OS'es?
