A bit late to the party, but since I am also interested in this subject I tried to do it myself and here's the result:
https://i.imgur.com/2SuAo6H.pnghttps://i.imgur.com/UXuXCqf.pngSome notes:
- The image was taken using view3dscene, which uses castle game engine as renderer.
- The room was exported using castle game engine's X3D exporter, with bump mapping disabled (I got a lot of errors if I enable it together with shadow mapping).
- Castle game engine doesn't support shadow casting from point light source so I changed all light sources in the room to spotlight.
- I removed 6 light sources so only 3 left (this is just my laziness, I didn't want to edit all of it using view3dscene).
- The lights were edited using view3dscene, but I couldn't save the scene (it saved but I got a lot of errors when I tried to load it). So the scene file attached here is the one without any major light modifications .
- Castle game engine doesn't support .tiff file format so in order to load the scene those .tiff files need to be converted to png.
Another one with only 1 light source + no shadow, but with bump mapping enabled
