trimming surfaces

[JochemvanderSpek]

Hi, is there a way to trim surfaces and create holes in verb ?

[pboyer]

No, not at this point.

[JochemvanderSpek]

ok :) I looked at the adaptive subdivision algorithm, what would be your judgment, is this something that can be relatively easily added ?

I think, need here the constrained triangulation :)

A trimmed Surface is usually called a Face. An Edge usually is a Curve, often a pair of HalfEdge's. Many of these are defined in Martti Mantyla's "Introduction to Solid Modeling".

Face's would require a few things be added to verb:

1. A Face representation with Loop's defining the outer boundary, inner hole boundaries (easy)
2. A tessellation algorithm for Face's (medium)

For completeness, it would be nice to have:

1. Face-X intersection where X is Face, Curve(medium hard).
2. Closest point algorithms for Face's (medium).

I previously started on Face's here, but only for planar faces.
