[K3d-development] Render-able Annotation types - 2, 3, 4, 5...n point relations

[Daniel S. M. <dsm...@gm...>]

I'd like to be able to use a node type that took point selections
across one or more other nodes (mesh etc.) and output a set of
floating point values that described the relationships between the
points. These relationships would at a minimum include distance,
angle, normal and center. This data could then be used by special
annotation nodes that used established CAD standards to represent the
relationships numerically and diagrammatically. These annotations (and
ideally all annotations) would be render-able.

I have notices there is some code in the API to do some of this, is it
an existing WIP?
