Synopsis

draw polytriangles

void GD2d_draw_polytri
(state, vcount, vert, fcolor, vcolor)
DDstate *state;
int vcount;
SHORT2 vert[];
FLOAT3 fcolor[];
FLOAT3 vcolor[];

Description

GD2d_draw_polytri draws a single polytriangle; that is, a series of connected lines, which the renderer forms into triangles.

Here's what a polytriangle looks like, with the polytriangle's vertices numbered:

{bmc \\Pcserver1\Public\Doc\Express4.xRefpages_nextRelease\gdapi_build\WINHELP\FH349067.TMP}

You set vcount to the number of vertices.

vert should specify vcount pairs of x and y values.

fcolor should be NULL. Or it should specify a color for each triangle; that is, ( vcount - 2) sets of red, green, and blue values.

vcolor should be NULL, or specify vcount sets of red, green, and blue values.
