Transformations

The glumpy.transforms module offers common transforms (interactive or not) that can be combined with other shaders and objects, espcially collections.

Warning

In all transforms, parameters must be passed by name (param=value) because positional arguments are reserved for the super class (Snippet).

A transform must be attached to a window such as to receive user events.
