Anamorphosis

Hello everyone, I am new to grasshopper and I'm doing a project architecture.

I would imagine that for such a projection you'd need a shape to project onto, an outline you wish to project and a point representing the location of the eye:

Thanks for this definition David, maybe a little tip for the people who want to use it, put the lens length of their viewport propreties to 17mm that is the one of average human eye. It's useful to check how it can look in reality or in a render from person point of view.

cheers

Its quite simple, really, and no need for grasshopper (unless you want a dynamic preview). You just have to intersect your geometry with your projected "image", like below. If you then set your view to isometric from the point of view of the projection you get the result.
