I would like to know if there is a way of manually creating volume grids. Like the data we obtain from mantaflow simulations or import from external vdb files.
For example, is the creation of volume grids exposed in the API? What I would like to do in such case is to manually create a 3d matrix in python inside Blender and directly pass such matrix to a volume object to be rendered. Without having to create an openvdb file and inport it.
