BoxGenerator

class cee.utils.BoxGenerator()

Helper class to tesselate a box with 6 faces

Useful when result values need to be mapped onto a set of 3D points defining a box. See the method createCuttingSolid in the example in Examples/DemoAppUg on how to do that.

Arguments:

origin (Vec3) – None
extent (Vec3) – None

Specify the box by providing an origin (min x,y,z of the box) and the extent in x,y and z direction.

Return type:: void
