Data representing a 3D object to be rendered is obtained, the data comprising: a mesh structure defining 3D co-ordinates for each of a plurality of object vertices; and a feature vector encoding visual characteristics for at least one object surface defined by the plurality of object vertices. Motion information indicative of motion of the object in a scene is received. Based on the motion information, the mesh structure is deformed by adjusting the co-ordinates for one or more of the plurality of object vertices. The deformed mesh structure is processed using a graphics pipeline comprising a vertex shader and a fragment shader to generate a rendered image of the scene. The fragment shader comprises an artificial neural network trained to output pixel colour values for the at least one object surface on the basis of the visual characteristics encoded in the feature vector.

A graphics pipeline reduces the number of tessellation factors written to and read from graphics memory. A hull shader stage detects whether tessellation factors for at least a threshold percentage of a thread group of patches are the same, and whether tessellation factors for a threshold percentage of the thread group of patches have the same value that indicates that the plurality of patches are to be culled or that the plurality of patches are to be passed to a tessellator stage of the graphics pipeline. In response to detecting that tessellation factors for at least the threshold percentage of the thread group are the same, the hull shader stage bypasses writing at least a subset of the tessellation factors for the thread group of patches to graphics memory, thus reducing bandwidth and improving efficiency of the graphics pipeline.

A graphics pipeline includes a first shader that generates first wave groups, a shader processor input (SPI) that launches the first wave groups for execution by shaders, and a scan converter that generates second waves for execution on the shaders based on results of processing the first wave groups by the one or more shaders. The first wave groups are selectively throttled based on a comparison of in-flight first wave groups and second waves pending execution on the at least one second shader. A cache holds information that is written to the cache in response to the first wave groups finishing execution on the shaders. Information is read from the cache in response to read requests issued by the second waves. In some cases, the first wave groups are selectively throttled by comparing how many first wave groups are in-flight and how many read requests to the cache are pending.

This invention provides a method and system for application graphics interface redirection and hardware acceleration in a heterogeneous computing environment, relating to the field of computer technology. First, the initial graphics instruction stream generated by the target application, conforming to a first graphics interface specification, is intercepted at the source computing node. Next, relevant information about the target computing node is obtained, and the initial graphics instruction stream is semantically parsed to obtain a sequence of instruction stream semantic units. Based on this sequence of instruction stream semantic units, an intermediate representation structure of the graphics pipeline is constructed and translated to generate a target hardware-executable graphics instruction stream. The target hardware-executable graphics instruction stream is transmitted to the target computing node via a cross-node transmission channel. At the target computing node, the graphics processing of the target hardware-executable graphics instruction stream is invoked to obtain graphics rendering result frame data, which is then returned to the source computing node via a return channel. This invention achieves graphics interface redirection and hardware acceleration in a heterogeneous environment.
