| Recalculating of point coordinates |
| The geometry engine will calculate the height, width, and depth for
every point, this process is called tessellation or triangulation. When the view
point is adjusted, the x, y, z index of each point is recalculated and those
cannot be seen (having a lower z-index) will be clipped. The engine will also
apply lighting effect. |
| As modern graphic
evolves tons of calculation due to lots of changes of view port and
object movements. The x, y, z coordinates have to be recalculated very
frequently. |
