Once the mesh design has been completed, the mesh, properties, data and terrain are automatically exported to create each of the files required to run the UBC-GIF codes. Now I'm interested in doing the opposite, taking a polygon mesh and approximating it in a voxel grid. That is think of a thick pipe (the cladding) which is is filled by a cylinder of different material (the core). Export options make it easy to sketch out an idea on-the-go and finish it up later in Qubicle or any other desktop voxel editor supporting the. a voxel grid is a 3D matrix that subdivides the 3D space into occupied on occupied small volumes called voxels. Attributes are arbitrary value field assigned to a mesh. Supported voxel formats. Oftentimes it is desirable to convert data from this format to a triangulated mesh that represents the surface of the volume described by the oc-cupied voxels. Desktop Voxel Editors are the easiest way (but not the only way) to convert meshes into voxels. In order to make this primarily ngon mesh deform properly I had to use the knife and make some cuts before symmetrizing which got a more acceptable surface rendering.
