A collection of functions to build spheres/ellipsoids, unions of spheres and test objects and voxel arrays or triangulated meshes.
meshSphereCreator.m - builds a single sphere or deformed sphere (ellipsoid) as a triangulated FV mesh struct.
voxelSphereCreator.m - adds a single sphere/deformed sphere to an input array (sets voxels inside the sphere to 1)
multiMeshElipsoidCreator.m - builds multiple spheres as FV mesh. overlapping spheres are united into a single object. Spheres can be deformed and rotated. Useful for building more complex objects from a union of spheres/ellipsoids
multiVoxelElipsoidCreator.m - builds multiple spheres as a binary array. overlapping spheres are united into a single object. Spheres can be deformed and rotated. Useful for building more complex objects from a union of spheres/ellipsoids
mulitiMeshToroidCreator.m - builds a set of tori (defined by major and minor radii and centre points) as FV meshes. Tori can be deformed and rotated to obtain different of toroids.
drawConnectingCylinders.m - draws a cylinders of user-defined width that connect sets of input points
starship.m/starship_voxel.m - apply the above functions to build a test object that loosely resembles a starship as an FV mesh or a binary array respectively.
