Shader stage creation

data Stage

A shader Stage.

stageID :: Stage -> GLuint

createTessCtrlShader :: (HasStageError e, MonadError e m, MonadIO m, MonadResource m) => String -> m Stage

Create a new tessellation control shader from a String representation of its source code.

createTessEvalShader :: (HasStageError e, MonadError e m, MonadIO m, MonadResource m) => String -> m Stage

Create a new tessellation evaluation shader from a String representation of its source code.

createVertexShader :: (HasStageError e, MonadError e m, MonadIO m, MonadResource m) => String -> m Stage

Create a new vertex shader from a String representation of its source code.

createGeometryShader :: (HasStageError e, MonadError e m, MonadIO m, MonadResource m) => String -> m Stage

Create a new geometry shader from a String representation of its source code.

createFragmentShader :: (HasStageError e, MonadError e m, MonadIO m, MonadResource m) => String -> m Stage

Create a new fragment shader from a String representation of its source code.

createComputeShader :: (HasStageError e, MonadError e m, MonadIO m, MonadResource m) => String -> m Stage

Create a new compute shader from a String representation of its source code.

Error handling

newtype StageError

Error type of shaders.

'CompilationFailed reason' occurs when a shader fails to compile, and the String reason contains a description of the failure.
