three

An orbit-camera viewer for three-dimensional fractal tilings. A cube grows from one of six designs - carpet, net, xtree, ytree, ztree, void - and is rendered as a lit mesh whose faces are stepped into four bands of shade. The camera turns, zooms, and pans freely, and the mesh can be handed to a GPU shader that re-uploads geometry only when the shape itself changes.

Playing

• Turn, zoom, and pan the camera; view snaps it back to iso, front, or top, and ortho toggles perspective.
• design, number (3, 5, 7, or 9) and level choose the fractal, capped at 32 cells per side.
• fill is any named color; alpha fades the faces toward glass.
• edges overlays the lattice lines, wireframe keeps only them, axes draws the reference frame.
• A census counts the grid, the filled cells, and the void.
