Function g3_CheckAndDrawPoly

renderer/HardwareDraw.cpp:133–136

like g3_DrawPoly(), but checks to see if facing. If surface normal is NULL, this routine must compute it, which will be slow. It is better to pre-compute the normal, and pass it to this function. When the normal is passed, this function works like g3_CheckNormalFacing() plus g3_DrawPoly().

// is passed, this function works like g3_CheckNormalFacing() plus
// g3_DrawPoly().
void g3_CheckAndDrawPoly(int nv, g3Point **pointlist, int bm, vector *norm, vector *pnt) {
  if (DoFacingCheck(norm, pointlist, pnt))
    g3_DrawPoly(nv, pointlist, bm);
}
