iCrosss Lite vs 4D Draw

iCrosss Lite is a free version of popular and unique educational application iCrosss which will help you learn solid geometry in an easy and funny way. iCrosss allows you to build a cross-section of each available polyhedra by your defined plane. The plane can be defined by three points (taps) on polyhedron faces. The application supports such kinds of polyhedra as regular polyhedra (Platonic solids), Pyramids, Prisms, Anti-prisms and Archimedean solids and duals. Polyhedrons are displayed in 3D representation, which allows you to rotate it in any direction. Cool chalkboard drawing style and fonts were used for awesome look’n’feel. To build a cross-section you have to put three points on polyhedron faces in order to define a section plane. There is two view modes that you can use for better cross-section experience: 3D mode and 3D cut mode. 3D cut mode is available only when you have already built cross-section. In this mode you can choose one of two solid pieces of initial polyhedron to continue work with. Available option for printing and sending via e-mail of the polyhedron or its section. You can access information regarding selected solid, which includes short description, number of faces, vertices, edges, web-link for more information and useful formulas. Polyhedra are organized in simple list divided by categories. A tutorial mode was designed for quick understanding. It will take you through the general application features. You can get access to few more polyhedra by making a post on your Facebook page. To display formulas custom rendering engine was developed. It visualizes a LaTeX formula format.

4D Draw is a simple vector-graphics app that lets you draw 4‑dimensional figures. It represents each point's first three coordinates in the usual way, while using color to represent the fourth coordinate. A built-in Help menu includes a “How to draw” page for an easy start, followed by a page of “4D construction ideas” to set you on your way towards visualizing 4-dimensional space. 4D Draw is intended for geometry students who want to learn to visualize 4‑dimensional space. People looking for a more recreational introduction to 4D should begin with 4D Maze instead. People looking for an even more recreational introduction to modern concepts of space and symmetry may enjoy the Torus Games or KaleidoPaint.
