Abstract
A three dimensional (3D) graphics application programming interface (API) extension provides support for specifying images in a shared exponent format. The shared exponent format is used to represent high dynamic range textures in a compact encoding to reduce the memory footprint needed to store the image data compared with other high dynamic range formats. Image data is encoded to and decoded from the shared exponent format using a pixel processing pipeline. Image data encoded into the shared exponent format can be decoded and used as texture data during rendering.
