Hi I'm working on a project where we need a Volum Rendrer. We are using OpenGL and Coin with SoQT. But we are looking for a Volum Rendrer, that dos not cost to much. We know about Sim-Voleon. This is to expensive. No open source.
Volume renderer? Expand, please as there are about ten thousand different meanings to this.
Volume renderers can include ray tracers, voxels, shadows, fog, collision testers, etc., etc., etc.
Also try a search on Google if you have not already. I tried searching for Volume Renderers and got a lot of seemingly relevant results, but as Bubba pointed out, they may not be exactly what you are looking for.
Sorry we need it for voxels
