Expand description

The Format enum represents a sized internal format of texture storage. The naming convention closely follows that of Vulkan, but it has a close correspondence with OpenGL.

The ‘_UNORM’ suffix denotes unsigned normalized formats. They are represented as unsigned integers internally, remapped to the [0.0, 1.0] floating point range in shaders. These are equivalent to the constants with no suffix in OpenGL.
The ‘_SNORM’ suffix denotes signed normalized formats. They are represented as signed integers, remapped to the [-1.0, 1.0] floating point range in shaders. This suffix is the same as in OpenGL.
The ‘_SFLOAT’ suffix denotes floating point formats, equivalent to the OpenGL ‘F’ suffix.
The ‘_SINT’ suffix denotes signed integer formats, exposed to shaders unmodified as integers. This is equivalent to the OpenGL ‘I’ suffix.
The ‘_UINT’ suffix denotes unsigned integer formats, exposed to shaders as unsigned integers. This is equivalent to the OpenGL ‘UI’ suffix.
The ‘_SRGB’ suffix denotes sRGB formats, which are all unsigned normalized integers. Textures in this format are assumed to be in the sRGB color space. Shaders reading from this format will automatically convert the color components to a linear color space, so the shader will only see linear values. Because GL_FRAMEBUFFER_SRGB is enabled by default in grr, when outputting from a shader to a render target with an ‘_SRGB’ format, OpenGL will convert the color components to an sRGB color space automatically. Alpha components, if they exist, are treated as linear throughout.
