-Currently the engine only supports particles and triangles/quads with flat colors. The aim is to keep the code as simple and modular as possible.
-
-At the moment the engine can render using <canvas> and <svg>. WebGL rendering would come at a later stage but feel free to fork the project and have a go.
-
-Although this allows 3D for iPhoneOS and Android platforms the performance on these devices is not too good.
+This project is work in progress. Before using it in a project be aware that the syntax may change from revision to revision without being backwards compatible. Currently there is no documentation, feel free to use the demos as a reference and/or read the source code. The engine can render using <canvas> and <svg> so far. WebGL renderer coming soon.
