HyperViewer
Show objects rotating in hyperspace.
(Actually, it can handle two and three dimensions, too.)
At the moment the only controls are a pair of sliders -- the left-hand one controls the dimensionality, and the right-hand one selects the object. Currently only the simplex, octoplex, and cube are implemented.
Documentation
... is pretty sketchy at this point, but there is a narrative of the development process at Adventures in hyperspace (and JavaScript) and Further Adventures in Hyperspace | Stephen Savitzky.
To do
- Replace the object-selection slider with a dropdown selector.
- Add sliders to control the overall rotation rate (frames per second) and the perspective viewing angles (N-2 in N dimensions).
- Add custom controls for the rotations. They have to be fairly small: in N dimensions there are (N)(N-1) different rotations, each in the plane defined by two of the axes. For 6-D you need 30. Each control needs a selector for the axes (probably a drop-down) a delta, and an initial value.
- Fix the simplex; placement of the final vertex is wrong.
- Add the dodecahedron, icosahedron, 24-cell, 120-cell, and 600-cell.
- Add the ability to read and write objects (vertices, edges, etc.)
- Add the ability to color (some of) the faces. See the (HyperSpace Express)[https://hyperspace-express.com/] logo for the motivation.
Implementation notes
This project was bootstrapped with Create Inferno App, as a way of becoming more familiar with Javascript and Inferno, (a lightweight alternative to React).
