Some Ideas about the scanning effect in the project

I think of a solution to the problem with the scanning effect in the project. Use rendering and alpha channel technology. The specific ideas are as follows:
Since the background is black, I need to create a target image. The scan effect requirement, the target size, and the problem solving method of the middle depth and four sides are still textures, And the size change is controlled by transparency. The problem of excessive color can also be achieved through Alpha. The method is similar.

 

The d3dxcreatetexturefromfileex method must be used for transparency.
