Add vertex split operation?

The opposite of an edge collapse.

What would be the difference with the current splitEdge? I'm not an expert here but I thought the inverse of an edge collapse would be to be splitting one of the edges left on the face of the edge that was collapsed.

Do you have pseudo code on how that would work?

Remi.

I don't have pseudocode handy. What I was thinking of was what's shown in Figure 1 of this paper: http://research.microsoft.com/en-us/um/people/hoppe/efficientpm.pdf Offhand, it doesn't seem to me like there is an edge-split operation that gives the equivalent mesh connectivity (but you could probably convince me I've missed it). For example, in that figure, which edge would I split to recover the same connectivity as in the left side of the figure?

Yes with the figure it's obvious now, you'd need a couple of operations to recover the edge collapse.
