The Voxel Mesh SOP is a shortcut for the common VDB from Polygons > Convert VDB workflow. It also has some extra features like projecting to the original mesh and dilating/eroding the volume.

Houdini 16.5 Update

Added Sharpen Features to the Voxel Mesh SOP, Which allows users to get better hard edge models.

    would be nice to have Dilate + Smooth + Erode + Final Smooth options like in particlefluidsurface/Filter Tab instead of just single erode
    or if the plan is to keep it simple, maybe just Close/Open slider (before Dilate/Erode) that would open or close holes of SDF as that is pretty useful operation and keeps the original shape better than Dilate + Mesh + Reproject

      Good suggestion! The idea is definitely to keep it simple though. How do you picture the Close/Open slider to work, I didn't see it in the particlefluidsurface node

      • tamte 6 years, 1 month ago  | 

        Open operation is Erode by N followed by Dilate by N
        Close operation is Dilate by N followed by Erode by N

        advantage of having them as Dilate/Erode combo is that you can insert smoothing inbetween, and that's what particlefluidsurface does
        however for simplicity when not inserting any operation inbetween it can be done as a single VDB Reshape set to Open or Close
        so it will just open/close holes, and smooths out sharp corners, so one opeen/close slider can do open in negative range and close in positive or something along those lines

          Oh Nice! Learnt something new today

          Yeah I think the single slider should work. I can also add a smooth in there anyways and just happen to keep it in between the dilate/erode so you can smooth it, or smooth it in the right place when opening/closing.

    I see that the " bounding box relative" checkbox is missing in the newest version of the toolset. How do I standardize the voxels over multiple pieces without this option?

    how i can get the same uvs????????????????????????????

    Can this tool make quad mesh ? As far as i know making vdb from polygon and convert it back to geo makes triangle geo. How does is make the geo quad?

    The sharpen feature saved my butt 2 weeks ago. Thanks!

    Is it possible to add the option to transfer the UVs to the new voxel mesh?
