Finding info on mapping a perlin texture into a 3D smoke inferno (volume texture)?

I have got one example from the web, but it is using the "Three" library and was written in Javascript, does anyone know where I can find info on how to put some perlin generated values, say it generates a nice 3D texture and I need to map it onto the lattice and it should generates a smoke inferno or some sort, maybe mapping out a IDirect3DCubeTexture thing into a lattice with U, V and W coordinates, I am looking for an example.. Thanks Jack
