So I’ve been having a problem for a while now (with multiple pieces of code) where the left hand edge of my vieport seems to be clipping weirdly. The clear color fills in just fine, but anything that I render close to the edge of the viewport dissapears. Sometimes. Resizing the window changes the amount that is clipped oddly, but it’s not a uniform change. One movement will have no effect, the same movement again might make the problem go away (or become unnoticably small…).
I have a picture of what I’m talking about at http://www.geocities.com/hloew/edge.html
That particular example happens to be an Ortho projection into a pane of an MFC app, but it could just as well be perpective in a normal window.
I’ve done some searches looking for similar problems on the forum, but honestly I’m not even sure what to call this… At first I thought I might be doing my viewport sizing calculations wrong (in some very odd way) but I’ve confirmed all of them as good. I also figure that if it were a vieport size issue then the clear color wouldn’t be drawn into the “dead” spot.
Oh… this only happens on the left edge. I’ve never seen it anywhere else, and believe me, I’ve been looking!
End of Edit
Anyone have any ideas what the heck this might be?
