Abstract
An input section inputs vertex data from a host CPU or a geometry process section to a rendering main process section. The rendering main process section performs a rendering process in accordance with the vertex data inputted into the input section. Therefore, the host CPU can directly write the vertex data, which does not require a geometry process, to a rendering process apparatus and a processing speed of an overall graphics system can be thereby improved.
Claims16
A rendering process apparatus connected to a host processor and a geometry process apparatus, comprising:
- a rendering main process section performing a rendering process in accordance with vertex data;
- an input section selectively inputting the vertex data from said host processor and said geometry process section to said rendering main process section as the vertex data for rendering process;
- and
- an input control section controlling output of the vertex data inputted into said input section, and controlling the rendering process performed by said rendering main process section.
A rendering process apparatus comprising:
- a rendering main process section performing a rendering process in accordance with vertex data;
- an input section inputting the vertex data from an outside to said rendering main process section as the vertex data for rendering process;
- and
- an input control section controlling an output of the vertex data inputted into said input section, and controlling the rendering process performed by said rendering main process section, wherein
- said input section includes:
- a pending register holding the vertex data inputted from said outside;
- and
- a plurality of vertex registers to which the vertex data held in said pending register is transferred.
