Index buffer block compression

A computer device, comprising:

• a memory;
• and
• at an application program interface (API) in communication with a graphics processing unit (GPU) in communication with the memory, wherein the GPU is configured to:
• determine whether at least one redundant index has been detected in a number of indices associated with a one or more primitives of a compressed index buffer block;
• in accordance with a determination that at least one redundant index has been detected in the number of indices, remove the at least one redundant index from the number of indices associated with the one or more primitives to form the compressed index buffer block as a set of one or more unique indices;
• and
• store, in an index buffer, the compressed index buffer block.

A computer-readable medium storing computer-executable instructions executable by an application program interface for rendering graphics in a computer device, comprising:

• instructions for determining whether at least one redundant index has been detected in an number of indices associated with an one or more primitives of an compressed index buffer block;
• in accordance with a determination that at least one redundant index has been detected in the number of indices, instructions for removing the at least one redundant index from the number of indices associated with the one or more primitives to form the compressed index buffer block as a set of one or more unique indices;
• and
• instructions for storing, in an index buffer, the compressed index buffer block.
