hello.
I must create a web site with a gallery of 3d model from sketchup and blender in collada format.
I would use webgl , but i'm not able to choose a good framework.
But what i would do is simple ;I wish use an orbit camera and custom shader and some default shader and may be transparency.
And , if is possible, compatible with ie 11
thanks.

http://threejs.org/ is a simple and powerful framework with alot of examples and tutorials on the web.

I would like to invite you to try out our Goo Engine:

www.gooengine.com

We have a very user friendly online 3D model importer supporting Collada.

When you export the 3D model you get a Goo project completely setup with an orbit camera.

And you can customize the shader to your hearts content. :-)

IE 11 is supported partially, but not completely yet. But we are working on it.
