arbfp1 - OpenGL fragment profile for multi-vendor ARB_fragment_program extension arbfp1 This OpenGL profile corresponds to the per-fragment functionality introduced by GeForce FX and other DirectX 9 GPUs. This profile is supported by any OpenGL implementation that conformantly implements ARB_fragment_program. The compiler output for this profile conforms to the assembly format defined by ARB_fragment_program. Data-dependent loops are not allowed; all loops must be unrollable. Conditional expressions are supported without branching so both conditions must be evaluated. Relative indexing of uniform arrays is not supported; use texture accesses instead. Requires OpenGL support for the multi-vendor ARB_fragment_program extension. This extension is supported by GeForce FX and later GPUS. ATI GPUs also support this extension.

OpenGL Extension Specifications
http://www.opengl.org/registry/specs/ARB/fragment_program.txt Number of temporaries to use, 32 by default. Maximum allowable (static) instructions. Not an issue for NVIDIA GPUs. Maximum number of texture instructions to generate. Not an issue for NVIDIA GPUs, but important for ATI GPUs (set it to 32). Maximum number of math instructions to generate. Not an issue for NVIDIA GPUs, but important for ATI GPUs (set it to 64). Maximum number of texture indirections. Not an issue for NVIDIA GPUs, but important for ATI GPUs (set it to 4). When multiple draw buffers are used, use the ATI_draw_buffers syntax so the generated code says "OPTION ATI_draw_buffers". The default, if this option is not specified, is to use ARB_draw_buffers. When multiple draw buffers are used, use the ARB_draw_buffers syntax so the generated code says "OPTION ARB_draw_buffers". This option is the default. Maximum draw buffers for use with ARB_draw_buffers. Set to 1 for NV3x GPUs. Use up to 4 for NV4x or ATI GPUs. Maximum allowable local parameters. Boolean to enable integer pixel centers. Boolean to enable upper left pixel origin. to-be-written
