Hello all - I use PCB Editor on 3 different machines at various times of the week. I have my user preference for the display of my cursor set to "infinite". On two of the three machines I experience a "ghosting" of the cursor as I move it across the screen. A remnant of the cursor display is left until I pan or zoom. Any ideas what might be causing this? I'm guessing my graphics card. Thanks in advance.
Hi Roger, that fix I described works like a champ for me. I have a potent win7 box with a nice radeon graphics card and the infinate cursor was a got to have so I did a bit of research on gaming forums of all places. Many games use open gl still, anyway as I recall there was a post I read about this game that had ghosting problems on vista so the fix was what I wrote earlier. Needless to say I was delighted when it worked with allegro.
I think the 3D engine in Allegro is very much a work in progress, I recall one of the service packs causing issues for us here. It couldnt display the shapes on the board.. got to love that, BTW another way to get a jpg of the 3d view of the board is to just hit the print screen key and paste the buffer into your favorite picture viewer... that works kind of good for me at this end.
Today I found another wierdo with the 3d engine. Suppose you have a rectangle and another smaller rectangle on top of it with a 1 mil gap between them so you get a good rendition of a SOIC package, well it displays and looks great but in the 3d viewer if you set the Z-Scale to say 10 to expose the inner layers of your board your shape that is sitting on the larger shape gets exploded in the Z plane too so it is like part of your package is floating in air.. Dont believe this was the intent of the deigners of the 3d engine... LOL
