Faster drillEdge()

[baburton]

Currently Triangulation<3>::drillEdge() is slow, because it does a second barycentric subdivision. It would be very nice to make this faster, perhaps by subdividing a little less aggressively.

Does Triangulation<3>::pinchEdge() solve this issue?

Does Triangulation<3>::pinchEdge() solve this issue?

Almost, but not quite: pinchEdge() is not monotonic, so it’s not a suitable drop-in replacement when monotonicity is required (such as in the intelligentSimplify() code). - b.

A note: drillEdge() is deprecated, and will be removed completely after the 6.0 release. If anyone needs to go back and examine the source code of the slow drillEdge() that does a second barycentric subdivision, look at the 6.0 sources, right at the top of the file engine/triangulation/dim3/subdivide.cpp .
