triangle3d(3alleg4) Allegro manual triangle3d(3alleg4)


triangle3d, triangle3d_f - Draws a 3d triangle onto the specified bitmap. Allegro game programming library.


#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);


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.
