Dear all!
I am really lost looking for an idea how I can implement the effect similar to one shown on this snapshot:
- here light spots on the sea surface are not needed, the scene should look light the result of sunlight penetrating through water.
You can also google for “light beams under water” to see other sample images that explains the task.
The result scene should have the following features:
- Several light beams (the number of beams probably to be defined externally)
- Some areas on the seabed lit as shown on the image above
- Light beams should not penetrate through other 3D objects that can appear in the scene. A “3D objects” is a regular shaded or textured 3D mesh.
So far I have understood that there is some technique called “god rays” - but not really sure it is applicable in my case. It seems I need also some approach to simulate the lit areas on the seabed, not sure if it is the same algo that renders the beams.
So thanks a lot in advance for any hints or advices, recommended readings, etc.!
Cheers,
Sergey
