POLY_MERGE Procedure

Merges two vertex lists and two polygon lists together so that they can be rendered in a single pass.

POLY_MERGE, vertex_list1, vertex_list2, polygon_list1,polygon_list2, vert, poly, pg_num

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 Vertex Lists and Polygon Lists in Chapter 7 of the PV-WAVE User's Guide.

---

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.

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.

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.
