Rerun

Cylinders3D

3D cylinders with flat caps.

This archetype is for cylinder primitives defined by their axial length and radius. For points whose radii are for visualization purposes, use archetypes.Points3D instead.

Orienting and placing cylinders forms a separate transform that is applied prior to archetypes.InstancePoses3D and archetypes.Transform3D.
