Graphics processing systems


A tile-based graphics processing pipeline 1 comprising a rasteriser 3, a renderer 6, a tile buffer 10, a write out stage 13 and a programmable processing stage 14. The tile buffer 10 stores multiple render targets for a deferred shading operation and the programmable processing stage 14 is operable to, under the control of graphics program instructions, read data from two or more of a set of multiple render targets for a deferred shading operation stored in the tile buffer 10, perform a deferred shading processing operation using the read data, and to write the result of the processing operation to an output render target in the tile buffer 10, or to external memory..

Depth scanning with multiple emitters


Mapping apparatus includes a transmitter, which is configured to emit, in alternation, at least two beams comprising pulses of light along respective beam axes that are mutually offset transversely relative to a scan line direction of a raster pattern. A scanner is configured to scan the two or more beams in the raster pattern over a scene.

Fast high-fidelity flood-filling on vector artwork


Techniques are disclosed for performing flood-fill operations on vector artwork. In one embodiment, a region under a point of interest (poi) of vector artwork is rasterized and flood-filled, and an initial bounding shape around that area is used as a first guess as to the area to be filled.

Culling for higher-order motion blur rasterization


Efficient overlap tests between a screen space tile and a moving triangle with per-vertex motion following bézier curves report conservative time bounds in which the moving triangle overlaps with a tile. The tests can be used in designing efficient hierarchical traversal algorithms for higher order motion blur rendering..

Scalable geometry processing within a checkerboard multi-gpu configuration


Systems, apparatus and methods are described including distributing batches of geometric objects to a multi-core system, at each processor core, performing vertex processing and geometry setup processing on the corresponding batch of geometric objects, storing the vertex processing results shared memory accessible to all of the cores, and storing the geometry setup processing results in local storage. Each particular core may then perform rasterization using geometry setup results obtained from local storage within the particular core and from local storage of at least one of the other processor cores..

Apparatus for automated rastering of an end effector over an airfoil-shaped body


A mechanism for adjusting the orientation of an end effector (e.g., a non-destructive inspection sensor) during movement over a contoured surface, comprising: (1) a pneumatic or spring-loaded plunger shaft that facilitates positioning of an end effector onto a highly contoured surface by allowing a wide range of vertical motion; (2) a rocker pivotably coupled to a distal end of the plunger shaft, the rocker being pivotable about a horizontal axis to allow a pair of follower wheels coupled to distal ends of the rocker arms to follow the contoured surface and keep the end effector oriented correctly relative to the surface without tipping over; and (3) a hozzle (i.e., an end effector holder) attached to the rocker for rotation therewith, the end effector being coupled to the hozzle by an elastomeric gasket or a plurality of springs which allow the orientation of the end effector relative to the hozzle to change in response to contact forces.. .
