3D scene in three-dimensional scene

Question

Consider a camera (on a plane) viewing a 3D terrain model. Imagine now that he takes a photograph of what he sees. I would like to see the relief from another camera (even move this camera around), and I would like to see an image made by a plane projected onto the landscape.

My current approach was as follows:

• Create a 3D scene representing the plan view.
• Create a three-dimensional scene representing the view of the observer.
• Inside the last scene there is a terrain model on which I project the entire three-dimensional scene from a plane.

This does not work properly - I will not go into details in detail yet, but can anyone tell if they think this will be the right approach?

Maybe one scene is enough with a mask of magic?

Answer 1

I think that the general way to do something like this is to visualize the planar appearance of the texture, and then impose this texture on the relief in the observer's view.

Unless, of course, is what you are already doing.
