Documentation
loadShader :: Shader s => FilePath -> IO sSource
Load a shader program from a file.
loadGeoShader :: FilePath -> IO GeometryShaderSource
Specialized loading for geometry shaders that are not yet fully supported by the Haskell OpenGL package.
linkShaderProgram :: [VertexShader] -> [FragmentShader] -> IO ProgramSource
Link vertex and fragment shaders into a Program.
linkShaderProgramWith :: [VertexShader] -> [FragmentShader] -> (Program -> IO ()) -> IO ProgramSource
Link vertex and fragment shaders into a Program. The supplied
IO action is run after attaching shader objects to the new
program, but before linking. This supports the use of
bindFragDataLocation to map fragment shader outputs.
linkGeoProgram :: [VertexShader] -> [GeometryShader] -> [FragmentShader] -> IO ProgramSource
Link vertex, geometry, and fragment shaders into a Program.
linkGeoProgramWith :: [VertexShader] -> [GeometryShader] -> [FragmentShader] -> (Program -> IO ()) -> IO ProgramSource
Link vertex, geometry, and fragment shaders into a Program. The
supplied IO action is run after attaching shader objects to the
new program, but before linking. This supports the use of
bindFragDataLocation to map fragment shader outputs.
namedUniform :: Uniform a => String -> StateVar aSource
Work with a named uniform shader parameter. Note that this looks
up the variable name on each access, so uniform parameters that
will be accessed frequently should instead be resolved to a
UniformLocation.
uniformScalar :: UniformComponent a => UniformLocation -> SettableStateVar aSource
Set a UniformLocation to a scalar value.
uniformVec :: UniformLocation -> SettableStateVar [GLfloat]Source
Set a UniformLocation from a list representation of a
low-dimensional vector of GLfloats. Only 2, 3, and 4 dimensional
vectors are supported.
uniformMat :: UniformLocation -> SettableStateVar [[GLfloat]]Source
Set a uniform shader location from a nested list matrix representation. Only 3x3 and 4x4 matrices are supported.
namedUniformMat :: String -> SettableStateVar [[GLfloat]]Source
Set a named uniform shader parameter from a nested list matrix representation. Only 3x3 and 4x4 matrices are supported.
uniformGLMat4 :: UniformLocation -> SettableStateVar (GLmatrix GLfloat)Source
Set a uniform shader location with a 4x4 GLmatrix.
