C++ (Cpp) R_ClearPlaneHash Beispiele

Beispiel #1

//
// R_ClearPlanes
//
// At begining of frame.
//
void R_ClearPlanes(void)
{
   int i;
   float a = 0.0f;

   // FIXME: borked in widescreen aspect ratios...
   int scaled_height = consoleactive ? video.x1lookup[Console.current_height] : 0;

   a = (float)(consoleactive ? 
         (scaled_height-viewwindowy) < 0 ? 0 : scaled_height-viewwindowy : 0);
#endif

   // opening / clipping determination
   for(i = 0; i < MAX_SCREENWIDTH; ++i)

   }

   R_ClearPlaneHash(&mainhash);

   lastopening = openings;

   // texture calculation
   memset(cachedheight, 0, sizeof(cachedheight));
   
   num_visplanes = 0;    // reset
}
