NAME
arbvp1 - OpenGL vertex profile for multi-vendor ARB_vertex_program extension
SYNOPSIS
arbvp1DESCRIPTION
This OpenGL profile corresponds to the per-vertex functionality introduced by GeForce3. This profile is supported by any OpenGL implementation that conformantly implements ARB_vertex_program.
The compiler output for this profile conforms to the assembly format defined by ARB_vertex_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 supported; but texture accesses are not supported.
3D API DEPENDENCIES
Requires OpenGL support for the multi-vendor ARB_vertex_program extension. These extensions were introduced by GeForce3 and Quadro DCC GPUs. ATI GPUs also support this extension.
PROFILE OPTIONS
- NumTemps=n
Number of temporaries to use (from 12 to 32).
- MaxInstructions=n
Maximum allowable (static) instructions.
- MaxLocalParams=n
Maximum allowable local parameters.
