POLY_MERGE Procedure
Merges two vertex lists and two polygon lists together so that they can be rendered in a single pass.
Usage
POLY_MERGE, vertex_list1, vertex_list2, polygon_list1,
polygon_list2, vert, poly, pg_num
Input Parameters
vertex_list1 — The first vertex list.
vertex_list2 — The second vertex list.
polygon_list1 — The first polygon list.
polygon_list2 — The second polygon list.
note | For more information, see the PV‑WAVE User’s Guide. |
Output Parameters
vert — A new variable consisting of vertex_list1 and vertex_list2 merged together.
poly — A new variable consisting of polygon_list1 and polygon_list2 merged together and modified so that it is compatible with vert.
pg_num — The total number of polygons in the merged list.
Keywords
Edge1 — A vector containing the edge colors for the first polygon list.
Edge2 — A vector containing the edge colors for the second polygon list.
Edge_List — The edge colors for the merged list.
Fill1 — A vector containing the fill colors for the first polygon list.
Fill2 — A vector containing the fill colors for the second polygon list.
Fill_List — The fill colors for the merged list.
Opaque1 — A vector containing the translucency factors for the first polygon list. (A translucency factor of 0 is completely clear. The higher the translucency factor, the more opaque the polygon.)
Opaque2 — A vector containing the translucency factors for the second polygon list.
Opaque_List — The translucency factors for the merged list.
Discussion
The merged lists returned by POLY_MERGE are suitable for input into
POLYSHADE or POLY_PLOT, where they may be rendered in a single pass.
