Stella4D 4.4

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 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 compounds 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.
