How to project a 2D image on its 3D surface?

Question

I have a 2D image and the suitable 3D model for it. And now I want to construct a 3D image. 

For excample the result should look similar to this.

 

Is there any way to do this with WPF? Thanks in advance.

Answer 1

Yes, WPF has the way to do it, but it is very very complex if you want to put the above image on the 3D object. We call it "stick texture" on the 3D model.

For example, we have a simple 3D surface, we want to stick one image on it, we have to do the following steps:

1. Split the surface to some triangles. Mark the points of these triangles as the index:

2. Map the points on this 3D surface to the points on the 2D image by its index:

3. You will view the 2D image on the 3D object as its texture.

This is a very simple texture sample. But your scenario is too complex and can be done manually. Please try to use the 3D building tools like 3D Max Studio, Blender or ZAM3D etc., then export the 3D models to XAML code.
