class VectorAxis vector axis where

Class for generically reading/writing vector coordinates.

Methods

get_coord :: axis -> vector -> Scalar

Read from the specified coordinate axis.

set_coord :: axis -> Scalar -> vector -> vector

Replace the existing value of the given coordinate axis.

class Project lo hi where

This class relates two vector types having consecutive sizes.

Methods

orthographic_down :: hi -> (lo, Scalar)

Reduce number of dimensions by one. (Return the dropped dimension as a Scalar.)

orthographic_up :: (lo, Scalar) -> hi

Increase number of dimensions by one. (Supply value for new dimension as a Scalar.)

perspective_down :: hi -> (lo, Scalar)

Perspective-project to N-1 dimensions. (Also return the distance from the camera as a Scalar.)

perspective_up :: (lo, Scalar) -> hi

Inverse-perspective project into N+1 dimension. (Supply the distance from the camera as a Scalar.)
