    摘要： A method and an apparatus provided for rendering three-dimensional computer graphic images which include both translucent and opaque objects. A list of objects which may be visible in the images is determined and for each pixel in the list a determination is made as to whether or not the object in the list may be visible at that pixel. A data tag is stored for a transparent object determined to be visible at the pixel, and the data tag and object data are passed to a texturing and shading unit when the translucent object is determined to be overwriting the location in a tag buffer already occupied by another data tag.

    摘要： A method and apparatus are provided for shading and texturing computer graphic images in a tile based rendering system using dynamically rendered textures. Scene space geometry is derived for a dynamically rendered texture and passed to a tiling unit which derives scene space geometry for a scene which references the textures. Scene space geometry for a scene that references the dynamically rendered texture is also derived and passed to the tiling unit. The tiling unit uses object data derived from the scene space geometry to detect reference to areas of dynamically rendered textures, as yet un-rendered. These are then dynamically rendered.
