AISA

Build Status GitHub stars GitHub forks GitHub issues GitHub license Twitter

AISA is a Software 3D Engine written in TypeScript. The only prerequisite for AISA to run properly is a HTML5 compatible web browser and a fast CPU (as you can guess JavaScript is not as fast as native code still it is running with a decent frame rate on my mobile phone). No WebGL is required. AISA does all the computations needed to rasterize a 3D scene in pure JavaScript by rendering to an offscreen framebuffer. This framebuffer is then copied to the backing framebuffer of a HTML Canvas that is setup as a render target.

Why a Software 3D Engine in TypeScript / JavaScript?

In fact it does not make sense to write your own 3D Engine in TypeScript since there are much better alternatvis like WebGL and OpenGL. This project has a pure educational purpose. My initial intention was to teach me some TypeScript and since I love computer graphics and always wanted to write my own 3D Engine from scratch I used this opportunity. Hence this project contains a lot of elementary algorithms from then field of computer graphics including clipping, triangle rasterization, geometric transformations and so forth.
