Grimoire.js acts as the bridge between WEB and CG.
WebGL development is typically hard due to the profound differences of the development flow between CG and WEB.
Grimoire.js provides a HTML-like markup to describe the scenes and DOM-like operation APIs to handle it. Web engineers will no longer take the cares of the graphics staff such as render loop, 3D mathmatics.
Grimoire.js provides a component system with APIs like Unity. CG engineers could focus on shader stuff to visualize better or complex graphics algorithm.
