I spent another handful of days extending and improving the rendering of 3D volume datasets in my path tracer. It now supports emission/temperature so that flames and heat can be used in conjunction with a volume's density channel (smoke, debris) to create explosions, smoking flames, and suchlike. It's no longer limited to just fog, smoke and clouds!
All images are raw outputs directly from the path tracer.
