Name

arbvp1 - OpenGL vertex profile for multi-vendor ARB_vertex_program extension

Synopsis

  arbvp1

Description

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.
