Abstract

Methods and devices for real time texture compression may include accessing graphics hardware incompatible compressed textures in a format incompatible with the GPU, and a metadata file associated with the graphics hardware incompatible compressed textures, wherein the metadata file includes at least one hint that provides information to use for compression of decompressed textures from the graphics hardware incompatible compressed textures into hardware compatible compressed textures. The methods and devices may include converting the graphics hardware incompatible compressed textures into the decompressed textures. The methods and devices may include selectively compressing the decompressed textures into the hardware compatible compressed textures usable by the GPU according to the at least one hint from the metadata file. The methods and devices may include transmitting the hardware compatible compressed textures to the GPU.
