Why Verge3D if we have Three.js?
It's not a secret that Verge3D is based on the cool and really popular WebGL framework called Three.js. Three.js is open-source, so you can download and use it completely free of charge. So what makes Verge3D worth the money?
Way better Blender, 3ds Max, or Maya integration
With Verge3D it's a completely different story. The framework was designed to be an artist-friendly tool. You just need to have some Blender, 3ds Max, or Maya skills to make any kind of 3D web content with Verge3D. Moreover it supports features of these modelling suites (cameras, lights, shadows, constraints, animation, etc) natively and strive to make Verge3D renderings look exactly the same.
