Multiple "Viewports" in a SDI interface
I am using MFC and OpenGL to create a 2D (and later 3d)visualization program, and the only problem I am having is with "layering" or having a separate view which is always fixed for example where as I am zooming in and out of another viewport. And I need this fixed viewport to always stay at a certain pixel coordinate (scaled of course).
Also I need to add border/plot/ticks to the viewport which I am using glOrtho to zoom in and out. I am not sure how I will go about doing that. Your help will be greatly appreciated, Thanks.
