Remarks
Three partial-precision floating-point numbers encoded into a single 32-bit value all sharing the same 5-bit exponent (variant of s10e5, which is sign bit, 10-bit mantissa, and 5-bit biased(15) exponent). There is no sign bit, and there is a shared 5-bit biased(15) exponent and a 9-bit mantissa for each channel. RGB9e5Float is implemented for Direct3D 11, Direct3D 12, Xbox One, PlayStation®4, OpenGL 3.0+, metal and Vulkan. The format is used for Precomputed Enlighten Realtime Global Illumination textures on supported platforms.
