A (3, n) array containing the 3D coordinates of each vertex. Must be in device coordinates.
Renders a given list ofpolygons.
A (3, n) array containing the 3D coordinates of each vertex. Must be in device coordinates.
TIP: To obtain device coordinates from data coordinates, use the POLY_NORM, POLY_TRANS, and POLY_DEV functions, in that order.
An array containing the number of sides for each polygon and the subscripts into the vertex_list array. For more information on the above two parameters, see Vertex Lists and Polygon Lists in Chapter 7 of the PV-WAVE User's Guide.
pg_num
The total number of polygons to plot. The x and y dimensions, respectively, of the current plot window in device coordinates.
NOTE: The winx and winy parameters are ignored if the Image keyword is present.
The color(s) to fill the polygons with:
| 255 | Fill the first polygon with color 255. |
| 200 | Fill the second polygon with color 200. |
| -1 | Don't fill the third polygon. |
| 0 | Fill the fourth polygon with color 0. |
The color(s) to draw the polygon edges with. edge_colors works in the same manner as fill_colors.To suppress the plotting of polygon edges, set edge_colors to -1.
NOTE: Polygon edges are not plotted if the Image keyword is present.
The translucency factor to use for plotting each polygon:
NOTE: The Image keyword must be used for poly_opaque to take effect.
On input, a 2D array containing the image on which to plot the polygons:
ZClip
If this keyword is present and nonzero, then polygons that do not have at least one vertex in front of the view point are not plotted.
