Not a bad thing IMO.. and the toporouter not only looks like it will be able to do excellent routing, its quality output will attract users to the software. That in turn helps attract development effort (or funding for it). > but we have rounding errors in the code as well. Are you thinking of the metric/imperial stuff, or the numerical issues present which keep causing the occasional bug with polygon intersections? If the latter, I've not got been able to implement the suggested snap rounding algorithm, but did have an attempt at getting some of the prerequisite Bentely Ottman intersection routines in place. (There's a branch for that ;)), No it doesn't work properly, and yes, I've virtually abandoned it for now.. other more pressing things to fix. > Which is important?

I just want you to see my point. 3D view came very very easily and cheaply from work I was doing which I would deem to be of VASTLY greater importance than negative layers. PCB's rendering is SLOW. Layers are OPAQUE, so working on multi-layer boards with lots of planes is near impossible. This barrier to use needs removing, and my pcb+gl branch addresses those shortcomings. Since GL is a 3D API, adjusting the projection / modelview matrices to present the board in 3D is _REALLY_ easy. (Granted, 3D models of components was just an amusing distraction) Still, this is the kind of thing which differentiates us (badly) from other packages which CAN model boards in 3D with components. If this costs us users, it costs the project. -- Peter Clifton Electrical Engineering Division, Engineering Department, University of Cambridge, 9, JJ Thomson Avenue, Cambridge CB3 0FA Tel: +44 (0)7729 980173 - (No signal in the lab!)
