title: Any Free open source WebGL editors?
body: <p>At first, I do apologize for my bad English.</p>
  
  <p>Our development team is working on a project, written in GWT that provides users the collaborative environment. Users can work on different projects, including animation making, image editing, 3D structure modelling and so on. So we have to provide them proper editors. I just want to know, are there any free/paid open source editors, so that we can embed in our project?</p>
  
  <p>It would be much better if the following specifications, are met:</p>
  
  <p>·        Better to be html5 compatible to benefit from latest technologies</p>
  
  <p>·        Can be webgl</p>
  
  <p>·        Should be open source</p>
  
  <p>·        Better to be java and gwt / or we should be able to wrap and use it</p>
  
  <p>·        Be reliable</p>
  
  <p>·        Support standard file formats</p>
