lightpoint | directional | ambient | null — the scene light that will
be cast on the shape. Use null for no lighting - all surfaces will have
the defined color. ('directional')
copyCPY_Step | string | CPY_Step[] — Create copies the
shapes vertices to replicate the shape in space. Copies of normals, colors
(if defined) and texture coordinates (if defined) will also be made.
usageTypeGLBufferUsage — use 'DYNAMIC' if the shape's vertices
will be updated very frequently ('STATIC')
