virtual |
Sends the Triangle to a FIG file format stream.
Warning! Because shading would generally require more colors in the colormap than allowed by the FIG file format, rendering a Gouraud triangle in an XFig file is the same as rendering a simple triangle whose filling color is the average of the vertex colors.
