I need to convert my loaded vdb file to a signed distance field using their fast sweeping algorithm. As input I have 3D grids with zeros and ones. I want to fill the rest of the area with SDF. To create the input vdb file, First I created a 3D numpy file then I converted it to vdb file. I have attached a slice of my 3D numpy file that I converted to vdb to create sdf from that. enter image description here
I have tried openvdb::v10_0::tools::fogToSdf(*grid, ISO value= 0) which is not working.
Please let me know if the post is not clear enough or if you have any more questions for the clarifications. I have tried openvdb::v10_0::tools::fogToSdf(*grid, ISO value= 0) which is not working.
