triangle3d3alleg4
Draws a 3d triangle onto the specified bitmap. allegro game programming library.
Usage
#include <allegro.h>
void triangle3d(BITMAP *bmp, int type, BITMAP *tex, V3D *v1, *v2, *v3);
void triangle3d_f(BITMAP *bmp, int type, BITMAP *tex, V3D_f *v1, *v2, *v3);
Overview
Draw 3d triangles, using either fixed or floating point vertex structures. Unlike quad3d[_f](), triangle3d[_f]() functions are not wrappers of polygon3d[_f](). The triangle3d[_f]() functions use their own routines taking into account the constantness of the gradients. Therefore triangle3d[_f](bmp, type, tex, v1, v2, v3) is faster than polygon3d[_f](bmp, type, tex, 3, v[]).
Read the beginning of chapter "Polygon rendering" for a list of rendering types you can use with this function.
