Hello, I have been playing Noise, Signed Distance Field (SDF), & Raymarching for while, thanks the excellent pack, FieldTrip, contributed by Kyle McLean/everyoneishappy. Now I would like to convert solid Mesh to SF3D in the coming project, but it seems to be difficult.
1.) I tried to render Geometry to Texture3D by Renderer (DX11 Volume), then change to SF3D by VolumeSDF (SF3D.source). However, the result seem to be an engraving on a cube.
2.) I know that SDF could be saved in Volume Texture. Thus, is importing texture an alternative way? Is there modelling software support rendering volume texture? I found that Houdini seemly can do it However, it also depends on VolumeSDF to read the DDS file.
Is the problem caused by fDistVolume function in Happy.fxn? Or I have missed something?
I was planning on updating the noodles & fieldtrip contribs pages sometime this month- they are both a fair bit ahead in the github versions now. The MeshToSDF node belong in noodles imo because it produces a discrete volume.
