NAME
arbfp1 - OpenGL fragment profile for multi-vendor ARB_fragment_program extensionSYNOPSIS
arbfp1
DESCRIPTION
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.
3D API DEPENDENCIES
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

PROFILE OPTIONS
- NumTemps=n
- Number of temporaries to use (from 12 to 32).
- MaxInstructionSlots=n
- Maximum allowable (static) instructions. Not an issue for NVIDIA GPUs.
- NoDependentReadLimit=b
- Boolean for whether a read limit exists.
- NumTexInstructions=n
- Maximum number of texture instructions to generate. Not an issue for NVIDIA GPUs, but important for ATI GPUs (set it to 32).
- NumMathInstructions=n
- Maximum number of math instructions to generate. Not an issue for NVIDIA GPUs, but important for ATI GPUs (set it to 64).
- MaxTexIndirections=n
- Maximum number of texture indirections. Not an issue for NVIDIA GPUs, but important for ATI GPUs (set it to 4).
- ATI_draw_buffers
- 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.
- 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.
- MaxDrawBuffers=n
- Maximum draw buffers for use with ARB_draw_buffers. Set to 1 for NV3x GPUs. Use up to 4 for NV4x or ATI GPUs.
- MaxLocalParams=n
- Maximum allowable local parameters.
