Patent number: 11861792Abstract: A method and apparatus are provided for tessellating patches of surfaces in a tile based three dimensional computer graphics rendering system. For each tile in an image a per tile list of primitive indices is derived for tessellated primitives which make up a patch. Hidden surface removal is then performed on the patch and any domain points which remain after hidden surface removal are derived. The primitives are then shaded for display.Type: GrantFiled: March 17, 2023Date of Patent: January 2, 2024Assignee: Imagination Technologies LimitedInventor: John William Howson

Patent number: 8446409Abstract: 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.Type: GrantFiled: April 18, 2007Date of Patent: May 21, 2013Assignee: Imagination Technologies LimitedInventor: John William Howson

Publication number: 20110254852Abstract: 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.Type: ApplicationFiled: March 18, 2011Publication date: October 20, 2011Inventor: John William Howson

Patent number: 6809730Abstract: Three dimensional computer graphic images are shaded by first supplying data which defines the objects to be inserted into the image, this data including depth data relating to the objects. A depth store (4) includes data for objects already inserted into the image and a depth comparison unit (6) compares the depth of an object to be inserted with the currently stored depth data for a particular pixel. The result of this is used to determine which of a number of depth operations is to be applied to the depth store (4). A blending value is selected for each pixel for combining the object with the image in dependence on the selected depth operation. A combining unit then combines the object with the image in proportions dependent upon the selecting blending value.Type: GrantFiled: February 14, 2003Date of Patent: October 26, 2004Assignee: Imagination Technologies LimitedInventor: John William Howson
