Volume rendering in WebGL [closed]

Question

I have:

1. a 3D array containing a 3d dataset to be displayed
2. a 4x4 matrix which defines spacing/scaling/orientation of the volume to be displayed
3. a opacity transfer function
4. a color transfer function

I would like to use ThreeJS to do volume rendering (MIP, RayCasting, etc.) of this data. Are there some shaders/demos available?

Should I work directly at the shader level or in javascript?

Any hint/code sample would be very much appreciated, Best
