It is a screenshot from the map editor of my 3D Engine, ming3D. The engine use Direct3D7 and is still under development. I have just finished the static light and shadow calculating part. The white cross is the light source and you can see the shadows on the floor and the wall.
Here are the features I would like to add to my engine:
Octree or Leafy BSP and PVS rendering
3D Object picking
Finally, thank you very much to Tobias Johansson for his excellent lightmap tutorial on http://come.to/polygone.
