3D mathematics is a subject related to computational geometry. 3D math is the technical basis of computer graphics and computer 3D game development, while computational geometry is a subject that studies how to solve geometric problems with numerical methods. Both 3D math and computational geometry are widely used in fields that use computers to simulate the 3D world, such as graphics, games, simulations, robotics, virtual reality, animation design, and more.

Torque 3D (full name: Torque Game Engine, TGE for short) is free, open-source and cross-platform 3D game engine developed by GarageGames (originally developed by Dynamix for the first-person shooter game Tribes 2 released in 2001) under the MIT license. It features powerful and complex rendering system, high-speed network transmission, authentic real-time editing, script editing system, as well as maximum flexibility and performance across a wide-range of hardware, and a full suite of tools for producing high-quality Windows and browser-based games development.

To make multi-platform 2D games, GameMaker Studio is definitely not inferior to the well-known and popular Unity which is one-size-fits-all to both 2D & 3D games development. Of course, as for merely 3D game development, AppNee suggests you choose the Unity instead. Because this task is beyond the strength and power of GameMaker Studio. This advice is especially suitable for non-professional and amateur enthusiasts of game development.

Unreal Engine (UE for short) is currently the most famous and widely authorized top 2D/3D multi-platform universal game engine for Windows and Mac OS X (written in C++) in the world, which has occupied 80% of the market share of the global commercial game engines. The great games developed based on it are numerous, including Unreal Tournament, Gears Of War, Mass Effect, BioShock, Borderlands, Mirror's Edge, and many other series of big game works.

As an OS platform leading the mobile application trends, Android released NDK to support the mixed developments of Java & C programming languages. This made it possible to port thousands of PC games (mainly written in C) onto Android platform and make them look more attractive by using a simple ARM Compiler.
