Abstract

The present invention relates to a prediction system for determining a set of subregions to be used for rendering a virtual world of a computer graphics application, said subregions belonging to streamable objects to be used for rendering said virtual world, said streamable objects each comprising a plurality of subregions. The prediction system comprises a plurality of predictor units arranged for receiving from a computer graphics application information on the virtual world and each arranged for obtaining a predicted set of subregions for rendering a virtual world using streamable objects, each predicted set being obtained by applying a different prediction scheme, a streaming manager arranged for receiving the predicted sets of subregions, for deriving from the predicted sets a working set of subregions to be used for rendering and for outputting, based on the working set of subregions, steering instructions concerning the set of subregions to be actually used.

Claims19

Dependent claims

A system comprising:

one or more computer processors;
one or more computer memories;
and
a set of instructions incorporated into the one or more computer memories, the set of instructions configuring the one or more computer processors to perform operations, the operations comprising:
receiving data describing a virtual world;
analyzing the received data using a plurality of predictors, the analyzing including identifying a predicted set of subregions belonging to streamable objects to be used for a rendering the virtual world;
combining the predicted sets of subregions into a working set of subregions combining the predicted sets of subregions into a working set of subregions based on an analysis of output from one or more predictors of the plurality of predictors;
determining priorities of steering instructions for loading subregions of the working set into a streaming cache memory to be used for the rendering, the determining of the priorities based on a further analysis of the output;
modifying an output of one or more predictors using the output of at least one other predictor;
and
performing at least one of adjusting the combining of the predicted sets of subregions based on an analysis of the modified output and adjusting the determining of priorities based on an analysis of the modified output.
