Abstract: When a shader program is to be executed by a graphics processor, the graphics processor is caused to execute at least two variants of the shader program and the operation of the graphics processor when executing execution threads for the different variants of the shader program is monitored. A variant of the shader program to be executed by subsequent execution threads that are to execute the shader program is then selected based on the monitoring of the operation of the shading stage when executing the execution threads for the different variants of the shader program.

Abstract: When a graphics texture mapping apparatus is to perform a texture filtering operation that uses the data values of a plurality of texels, the texture mapper first determines whether any of the data values of the texels to be used for the texture filtering operation are the same, and then selects a texture filtering operation to be performed using data values of the texels based on the determination. The texture mapper then performs the selected texture filtering operation using one or more of the data values of the texels to provide the required texture filtering operation output result.

Abstract: This disclosure relates to various systems and methods related to preventative laser-based treatment of a dental tissue; for example, to prevent a patient from forming cavities. In some instances, a laser-based treatment system can generate a laser beam pulse with a fluence profile at a treatment site that results in either an increase in acid resistance of the tissue or removal of carbonate from the tissue, without melting or ablating the tissue. In some instances, the laser-based treatment system can direct the laser beam to various locations within a treatment site according to a temporal and/or spatial pattern, that results in either an increase in acid resistance of the tissue or removal of carbonate from the tissue, without melting or ablating the tissue. Many other systems and techniques for preventative and other laser-based treatment are also described.

Abstract: A dental laser treatment system includes a treatment laser beam and a pilot (e.g., aiming/marking) laser beam sharing a collinear beam path, where the beam path is guided by a guidance system through a handpiece/main chamber assembly having a beam exit. A laser beam presence detector is removably affixed to or within the handpiece/main chamber assembly. The laser beam presence detector provides feedback to a computer which can control actuation of the treatment laser beam and the pilot laser beam, and the beam guidance system. The computer performs a search for determining the center location of the beam exit based on the feedback and controls the beam guidance system to guide the beam path approximately to the center of the beam exit, thereby providing automatic alignment of the laser beam with the beam exit or an optional hollow waveguide.

Abstract: A target system has a splatter pack attached to a target panel. The splatter pack acts as a receptacle for a fluid that provides visual confirmation that the target has been hit as the pack bursts upon impact by a projectile. The splatter pack is formed by an array of chambers that are arranged in a staggered pattern. As the pack bursts, the fluid explodes out and leaves a splatter pattern on or about the target panel. The burst and residual splatter allow the marksman to see whether or not an accurate shot was delivered without having to closely examine the target. The splatter pack is removably secured to the target panel by one or more fasteners. Each one of the chambers in the interior portion of the splatter pack are intersected by at least one of the channels that are formed between adjacent chambers.

Abstract: A graphics processing system sorts graphics primitives for rendering into lists corresponding to different sub-regions of a render output to be generated, each list indicating primitives to be processed for the render output. A primitive list building unit divides a render target into various sub-regions, determines which sub-regions a primitive falls within and adds the primitive to the primitive lists corresponding to those sub-regions. The primitive list building unit also records the positions of the primitives in a pair of histograms which show the distribution of primitives across the render output. Once all primitives for the render output have been sorted into lists, the histograms are outputted to a predictor processor. The predictor processor then determines a set of sub-region sizes to be used when sorting primitives for the next render output to be generated into lists, based on the histograms.
