20100238269 | SYSTEM AND METHOD FOR TRIDIMENSIONAL CARTOGRAPHY OF A STRUCTURAL SURFACE - System and method for tridimensional cartography of a structural surface. Two wires are extended in front and along the structural surface so as to define a reference surface. A measuring unit comprising a laser arrangement and a camera is moved in front of the structural surface so as to progressively scan the surface. Tow distinct light planes directed toward the structural surface are projected by means of the laser arrangement. Images of the structural surface containing lines resulting from an intersection of the light planes with the structural surface and four reference points resulting from an intersection of the light planes with the wires are captured by means of the camera. The images are processed to determine the 3D coordinates of the lines defining the mapping in a reference system bound to the reference surface considering the position and the orientation of the measuring unit based on the reference points. | 09-23-2010 |

20150317825 | GRAPHICS PROCESSING SYSTEMS - To simulate the effect of shadows in an image being rendered a light source bounding frustum is produced for a tile for a light source, and used to determine a set of geometry for the tile that could cast a shadow in the tile. The determined set of geometry is then used to determine a light source visibility parameter for each sampling position in the tile by determining for each tile screen space sampling position, whether rays cast between the tile sampling position and a set of sampling positions representing the light source would intersect occluding geometry or not. The determined number of visible light source sampling positions for each tile sampling position is used to determine a light source visibility parameter value for each tile sampling position, and the determined light source visibility parameters are then used to modulate the light source when shading the geometry. | 11-05-2015 |
