Data transformation and clipping in a graphics display system |
摘要 |
A display processor in a raster graphics display system includes a transformation, clipping and mapping feature which controls the transformation, clipping and mapping of graphics data. A control byte contains 5 bits identified as: M-Window to viewport mapping; P-perspective projection; D-2D/3D mode; T-transformation; and C-clipping. Each bit in the control byte is tested to determine what operations are to be performed on the figure to be drawn.
