MeshcatCone Class Referencefinal

Detailed Description

Definition of a cone.

Its point is at the origin, its height extends in the direction of the frame's +z axis. Or, more formally: a finite section of a Lorentz cone (aka "second-order cone"), defined by

 sqrt(x²/a² + y²/b²) ≤ z;  z ∈ [0, height],

where a and b are the lengths of the principal semi-axes of the horizontal section at z=height().

This shape is currently only supported by Meshcat. It will not appear in any renderings, proximity queries, or other visualizers.
