Is it possible to draw simple figures in a 3 dimensional Mat ?

I want to draw for example a rectangle bended backwards and project it to a 2D Mat to see effects of the perspective. If no, how can I create 3D Mats with simple shapes ? I have never used graphic engines, what is the simplest approach ?

cv::projectPoints can solve that problem. It computes the projection of 3d Points for a camera with given intrinsics. OpenCV 3.0 now also has the Viz-Module which can render simple objects like OpenGL but that could be a bit of overkill.
