See attached example, I create some example geometry t work with.
I then create a VDB volume. I set the voxel size to 0.25, and I set the Exterior Band Voxels to 2.
I try two approaches:
- In one I create a signed distance field.
- In the other, I create an unsigned distance field.
I then use the Points from Volume SOP to generate a grid of points that are close to the geometry surface, with a tolerance of 0.2.
Neither seems to produce the right result. The unsigned field produces nothing, and the signed field produces some points, but many points are also missing.
I guess I must be doing something wrong…
