Methods

hasVertexArrayObjects :: Ctx -> IO Bool

This extension is fundamental and Ombra won't work without it.

hasFloatTextures :: Ctx -> IO Bool

Required for using float textures and GBuffers.

hasDrawBuffers :: Ctx -> IO Bool

Required for using GBuffers with more than 4 GFloats.

hasStandardDerivatives :: Ctx -> IO Bool

Required for the dFdx, dFdy and fwidth shader functions.
