Explore 4D world as viewed by the eyes of imaginary 4D creature that uses volumetric (3D) space for visual sensing instead of planar (2D) space like we do.A brand new 4D rendering engine was created for a Freespace-like game. Based on yet incomplete version of that engine, 2 modules were created and included into this package:Magic Manycell is a puzzle game inspired by Magic Cube. Just like a cube that has 6 square faces, each of which is split into 3x3 smaller squares, in 4D a tesseract has 8 cubic cells, each of which is split into 2^3 or 3^3 smaller cubic cells. Then, in Magic Cube, player can rotate 3x3x1 slice of the cube around single axis; in 4D, player can rotate 3x3x3x1 slice, but not around single - around any of 3 orthogonal axes! (note: Manycell is a term used to describe Polychoron that has its flat cells split into smaller cells which all stay in original cell's flat subspace).Currently 3 different Polychorons are supported for Magic Manycell game - Tesseract with 2^3 cells, Tesseract with 3^3 cells and a 16-cell which has whole cells but is such a special figure that it can be rotated like Tesseract 2^3 - by splitting it exactly in 2
