Stella4D Description

Stella4D expands on Great Stella to include four-dimensional polytopes, known as polychora. See 3D cross-sections animating in real-time, see complete polychora projected into 3D and try 4D rotation, and view 3D nets and vertex figures of 4D polytopes. Stella4D Features: - Includes all features from Great Stella (see above). - Built-in models (in addition to those from Great Stella): -All 16 regular polychora. - All 1849 known uniform polychora. This is the only place you can see all of these. -A separate category groups all the convex polychora together. -Any uniform duoprism or antiduoprism can be created. Various uniform fissaries, scaliforms, and com-pounds are also included. -Duals of any polychoron are available. -Compounds of polychora with their duals. -View 4D models projected into 3D (perspective or orthogonal, with or without back-cell or front-cell removal). Interactively rotate the projection direction, or choose cell-first, face-first, edge-first or vertex-first. The default auto setting usually finds the projection giving the greatest symmetry. -View 3D cross-sections of 4D polytopes. -Interactively change the slicing depth in real time. -Slice cell-first, face-first, edge-first or vertex-first. -Interactively rotate the slicing plane. -See how the cross-section fits into the 3D projection of the original 4D model. -Snap the cross-section depth to the nearest vertex, and step through the depths where the plane hits a vertex. -Show small spheres when true vertices are close to the slicing plane. -Color cells along the slicing direction to create more colorful slices. -View 3D nets of 4D polytopes. Manually rearrange the cells in the net. -View 3D vertex figures and individual 3D cells of 4D polytopes. -You may use the model from any view as the new 3D base model (for creating nets, stellations etc). This includes 3D cross-section, 3D nets, 3D projections of 4D models, 3D vertex figures, or individual 3D cells. -Truncate, rectify, and expand 4D polytopes. -Create convex hulls or convex cores of 4D polytopes. -Delete or keep just one part of a 4D compound. -Create 4D prisms from 3D polyhedra. -When displaying using spheres and cylinders, their size will vary correctly according to the 4D projection (spheres further away in 4D will appear smaller in a perspective projection). -Most of Great Stella's colouring and hiding options for faces are supported for cells in 4D. Undo/redo, memory slots and Measurement Mode are also supported. -Import any 4D model in 4D OFF format.
