Sommaire

NAME

vp20 - OpenGL fragment profile for NV2x (GeForce3, GeForce4 Ti, Quadro DCC, etc.)

SYNOPSIS

   vp20

DESCRIPTION

This OpenGL profile corresponds to the per-vertex functionality introduced by GeForce3.

The compiler output for this profile conforms to the assembly format defined by NV_vertex_program1_1 (which assumes NV_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 NV_vertex_program and NV_vertex_program1_1 extensions. These extensions were introduced by GeForce3 and Quadro DCC GPUs.
