Shape Information

\n Tesseract (4D Cube)
\n Vertices: 16
\n Edges: 32
\n Faces: 24
\n Cells: 8

\n The tesseract is the 4-dimensional analog of a cube. Each vertex connects to 4 edges, and the shape can be visualized as two 3D cubes connected through the 4th dimension.\n

Understanding Cross-Sections

\n A cross-section of a 4D object is created by intersecting it with a 3D hyperplane. \n This is analogous to how a 2D slice reveals the interior of a 3D object.\n

Position: Where the hyperplane cuts through the 4D space
Normal Vector: The direction perpendicular to the hyperplane
Result: A 3D shape that shows the \"interior\" of the 4D object
