Changeset 2882 for trunk/packages/vizservers/nanovis/VelocityArrowsSlice.cpp

Timestamp:

Message:

Assume baseline requirement of NV40 GPU, which translates to Cg profiles vp40
and fp40, which in turn require NV_vertex_program3 and NV_fragment_program2
assembly shader extensions. Add explicit check for these extensions.
