> # 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.

> # PROFILE OPTIONS

> None.
