I am using OpenGL in C++ to create graphics in a program of mine. In the window, there is the main section and a sidebar.
My problem is that I do not know how to relocate the vanishing point in my window. Currently, it is at (0, 0), which is the default. I want to make it shift to (-0.25, 0) so as to give the illusion that the sidebar is not part of the main section.
