I am trying to do a script which might be weird. Pls check the pics below as to explain what I wanna do. In short, I am thinking a way to transform the edges of geometries to a plane, where the 2D edges will perfectly match their parents in 3D scene:
The middle plane is where I want the 2D edges(shown in blue-ish) to be projected from 3D geometries.
As you can tell, the blue-ish lines are mismatched somehow and I figured the issue might be my projecting 3D wireframes directly to the plane JUST by sole vector, the Normal of the camera point plane.
So, I guess there must be an equation to transform wireframes of 3D models to a certain plane, which in 3D view port they two can be perfectly matched?
