I am creating an editor where I have "grabhandles" that can be dragged to transform a primitive object.
My problem is that I can't find the correct solution to show these grabhandles in a perspective view.
They need to have the correct position AND same size independent of where they are,how far away they are on the perspective viewport and independent of what the viewport dimensions are.
In orthographic mode I do not have this problem as I create the handle polygons by multiplying it with a zoom factor.
