I'v solved my problem. I find the real coordinate (onscreen) with Xform, then change the world matrix to an Identity. I then use the coordinate I found to write it to the screen with 'actual' pixels. This is more like opengl than I thought it would be :P I agree, given 5 minutes more thought I could have saved $2000 and lotsa crap .... by using opengl. Altho there's quite alot of questions that popup like: Will they spend $X on a screen card. Who could maintain the thing after I'm done? Would they realy have payed me what it's worth ... Think I'll do it for fun and try to sell it to them anyway ;-) Thanks. Reyn Vlietstra.

There are quite alot of thing I would like to do if I move the thing to opengl. I think not having an accelerator would make it unusable. Qt is fast enough for a 2D representation ... I have a little problem I'll post later ... seams that moving objects' refresh regtangles merge(?) and to update the combined background get very slow.

Thay had to have loved reading that! ;-) How else could I work myself up in this world ? :P > EBo -- Reyn Vlietstra.

But is it worth paying this much when the main purpose of a project is to represent something in 3D ? Then again, the qsocket etc. prob. tips the scale. (just thinking out loud) Reyn Vlietstra.
