This modifier is the opposite of the recently added Mesh to Volume modifier. It converts the "surface" of a volume into a mesh. The "surface" is defined by a threshold value. All voxels with a density higher than the threshold are considered to be inside the volume, while all others will be outside. By default, the resolution of the generated mesh depends on the voxel size of the volume grid. The resolution can be customized. It should be noted that a lower resolution might not make this modifier faster. This is because we have to downsample the openvdb grid, which isn't a cheap operation. Converting a mesh to a volume and then back to a mesh is possible, but it does require two separate mesh objects for now. Reviewers: brecht Differential Revision: https://developer.blender.org/D9141
