TGSI_SEMANTIC_CULLDIST
|

""""""""""""""""""""""
|
||||
|
||||
Used as distance to plane for performing application-defined culling
|
||||
of individual primitives against a plane. When components of vertex
|
||||
elements are given this label, these values are assumed to be a
|
||||
float32 signed distance to a plane. Primitives will be completely
|
||||
discarded if the plane distance for all of the vertices in the
|
||||
primitive are < 0. If a vertex has a cull distance of NaN, that
|
||||
vertex counts as "out" (as if its < 0);
|
||||
The limits on both clip and cull distances are bound
|
||||
by the PIPE_MAX_CLIP_OR_CULL_DISTANCE_COUNT define which defines
|
||||
the maximum number of components that can be used to hold the
|
||||
distances and by the PIPE_MAX_CLIP_OR_CULL_DISTANCE_ELEMENT_COUNT
|
||||
which specifies the maximum number of registers which can be
|
||||
annotated with those semantics.
