Record vector field #591

Closed bkfichter closed 2 years ago

bkfichter commented 2 years ago

Thinking out loud and I haven't fully thought this through. I'm wondering if there is a way to get a vector field snapshot for each (or some multiple) voxel per frame. Store along side the bake file. Maybe that can be used in geo nodes to apply a force to meshes to simulate buoyancy. When physics are added to geo nodes, all of this could work together. In the meantime, a file that contains the array for the vector field (per frame) could be fun to use in python to works towards something. Thoughts?

Hi, at the moment there is not a way for addons to import vector field data into Blender. The FLIP Fluids addon does not export this data as there is not a use for it yet.

We will need to wait and see how physics and nodes develop in Blender and if addons will have access to this system.

Sorry I thought I was posting under feature request. Plus that's why I was suggesting exporting a vector field file next to bake file. (Append python tuples to a file when the vectors are being calculated.) Then that data could be used.
