use of octree with surface meshes

[otaolafranc]

Hello, I found by chance this repo, and would like to compare the quality of the resulting meshes to snappyHexMesh results, which takes as input a surface mesh (for the geometry) and a background mesh, in the examples in the unit test, I didn't saw anything similar, is this a possible workflow of this code? thanks in advance

Hi, My implementation is solely focusing on space partitioning.

There are at least two major issues:

• Child node creation: only the relevant child nodes are created. But you would need the empty children also, to get a continuous mesh.
• Bounding boxes of the contour elements are not detailed enough for the wanted meshes, It would require a manual finitization of the contour for small boxes.

Overall, with a lot of hacks and tricks, you may able to reproduce Figure 4.11, but my opinion is that not worth the hussle. You can easily find many free mesh generator libraries.
