KnifeEdge¶

class poppy.KnifeEdge(name=None, rotation=0, **kwargs)[source]¶

A half-infinite opaque plane, with a perfectly sharp edge through the origin.

Use the ‘rotation’, ‘shift_x’, and ‘shift_y’ parameters to adjust location and orientation.

Rotation=0 yields a knife edge oriented vertically (edge parallel to +y) with the opaque side to the right.

Methods Summary
