- NAME: ambient
-
- CELL CONTENTS:
- Each cell contains two facets. Neither facet contains
- per-vertex or per-facet attributes. Both facets are at the
- same Z value. HLHS_removal is always disabled. The two facets
- overlay. The upper left of these facets occludes the lower
- right one. The upper left facet is front facing while the
- lower right one is backfacing. Within a cell all attributes
- are constant, however some attributes will effect the
- frontfacing facet and others will effect the backfacing facet.
-
- Of the 14 variations of this test the output primitive used
- to create the facet is:
-
- | (ambient.v01 - ambient.v02) use "Polygon" as the facets.
- | (ambient.v03 - ambient.v04) use "Polygon3" as the facets.
- | (ambient.v05 - ambient.v06) use "Fill_area_set" as the facets.
- | (ambient.v07 - ambient.v08) use "Fill_area_set3" as the facets.
- | (ambient.v09 - ambient.v10) use "Triangle3" as the facets.
- | (ambient.v11 - ambient.v12) use "Quad_mesh3" as the facets.
- | (ambient.v13 - ambient.v14) use "Index_polygon3" as the facets.
- | (ambient.v15 - ambient.v16) use "Non_uniform_bspline_surface" as the facets.
