Documentation

class VectorAxis vector axis where Source

Class for generically reading/writing vector coordinates. Methods get_coord :: axis -> vector -> Scalar Source Read from the specified coordinate axis. set_coord :: axis -> Scalar -> vector -> vector Source Replace the existing value of the given coordinate axis. Instances VectorAxis Vector4 AxisW VectorAxis Vector4 AxisZ VectorAxis Vector4 AxisY VectorAxis Vector4 AxisX VectorAxis Vector3 AxisZ VectorAxis Vector3 AxisY VectorAxis Vector3 AxisX VectorAxis Vector2 AxisY VectorAxis Vector2 AxisX VectorAxis Vector1 AxisX

class Project lo hi where Source

This class relates two vector types having consecutive sizes. Methods orthographic_down :: hi -> (lo, Scalar) Source Reduce number of dimensions by one. (Return the dropped dimension as a Scalar.) orthographic_up :: (lo, Scalar) -> hi Source Increase number of dimensions by one. (Supply value for new dimension as a Scalar.) perspective_down :: hi -> (lo, Scalar) Source Perspective-project to N-1 dimensions. (Also return the distance from the camera as a Scalar.) perspective_up :: (lo, Scalar) -> hi Source Inverse-perspective project into N+1 dimension. (Supply the distance from the camera as a Scalar.) Instances Project Vector3 Vector4 Project Vector2 Vector3 Project Vector1 Vector2
