## Function Documentation

## ◆ PT()

PT | ( | Lens |  | ) |

Allocates a new Lens just like this one.

Returns true if the lens represents a linear projection (e.g. PerspectiveLens, MatrixLens), and therefore there is a valid matrix returned by get_projection_mat(), or false otherwise.

Computes the complete transformation matrix from 3-d point to 2-d point, if the lens is linear.
