* | tgsi: adds tgsi utility to transform a shader to support point sprite | Charmaine Lee | 2015-09-01 | 1 | -0/+38 |
This adds a tgsi utility tgsi_add_point_sprite to transform a geometry shader to emulate wide points by drawing quads. This utility adds an extra output for the original point position if the point position is to be written to a stream output buffer. It also assumes the driver will add a constant for inverse viewport scale after the user defined constants. Reviewed-by: Brian Paul <[email protected]> |
