NAME¶
triangle3d, triangle3d_f - Draws a 3d triangle onto the specified bitmap.
Allegro game programming library.
SYNOPSIS¶
#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);
DESCRIPTION¶
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.
