Re: gEDA-user: PCB+GL+3D (Z-coord) Eye-candy
Just proof of concept stuff... http://www2.eng.cam.ac.uk/~pcjc2/geda/pcb+gl_3d/ There isn't anything clever here.. just the same PCB+GL translucent rendering I had before, but with a 3D virtual trackball to rotate the viewport. Very cool! How do you set the origin for the viewport? One thing you might want to do is to provide a number box for azimuth, elevation, and z-angle, and z-distance (optional, for zoom) from the origin to the camera. That's the easiest way to reset your view when things get squirrelly from the oval graphic control or revisit an angle that you liked previously. -Ethan ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

Very cool! How do you set the origin for the viewport? The origin for rotation is the centre of the visible screen. The old pan and zoom actions (scroll bars etc..) are used to adjust the piece of the board being previewed. Still a bit of a mix of paradigms, (2D + 3D), but it seems to work well enough for a demo.

WOW, that looks nice! And having that might help me to remember that PCB keeps defaulting to putting the rat lines on the component side for a single sided board, so when I finally produce the board, I have to turn it over and flip all the components.

Mike Rat lines have no default layer, they are just drawn on top of which ever view is shown. I wonder if the issue you've noted is due to the fact that layer 1, the default selected drawing layer is component. Switching to layer 2 solder before drawing any tracks is probably what you need to do.

The other kludging for these demos is some code to guess at a Z-value for various rendered layers, repeat drawing of pins + vias on each layer etc.. this is really crying out for some better way of some extra information in the layer stack. Btw.. the white ellipse on the left-hand bar is my 3D trackball sphere - I left it as a separate control for now. Code is on repo.or.cz local_customisation_no_pours branch if anyone is interested. Also.. I've rebased my branches (including the more established PCB+GL code) on PCB's git HEAD. There was also a fix for a crasher bug which just went in, so anyone using PCB+GL might want to update. (before_pours branch). Best wishes, Peter C. ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

Sweet! I wonder if we can add some thickness and get a ben mode style 3-D image? ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
