rendering. Some time ag= o I've tried to check if it is possible to

We have a working opengl HID in= pcb-rnd for more than a year by now.

If you m= ean incorporating more of Peter's 3d related patches: in pcb-rnd
<= div>we want to have a 2.5d editor, not a 3d editor, so the 3d parts shouldn= 't
be merged.

Instead we have an= openscad export plugin that lets openscad do very nice
3d re= nders.

Btw, merging anything forth and back be= tween pcb-rnd and mainline became
hard lately, beause around = summer 2016 I decided to change project
direction and really = go and fix our decade old bugs and desing problems,
see below= . This obviously made the code diverge a lot.

By the way I was comparing both versions and = I found some differences (not
sure if this is planned or not)= . With Peters openGL version I can draw
tracks on soldermask = layer (create holes in soldermask), while with mainline
pcb i= t is impossible.

In pcb-rnd we we= nt on cleaning up the code and replaced most of the data

mode= l during the past ~1 year. Thus we also have editable soldermask layer
<= /div>

-- but not as a patch or fix, but as a natural consequence of the= new data

model that doesn't have special cases for the mask = layer. And it's not in

a branch, but in production code, alre= ady tested on a number of fabbed

boards, thanks to our users.=

(The data model redesign solved a lot of our = decade old problems the same

way, without adding more kludges= on the existing kludges. We have editable

paste layer too, a= nd footprints can contain any of those edits: any object

on a= ny layer, including text on mask, polygon on paste or arc on outline.

Plus anything can become a "pad" and thermal works on any shape - = you

don't need to draw tiny lines manually to connect your sm= d pads to

polygons any more. And polygons can clear other pol= ygons so you don't need

to cheat with thick lines to draw a P= SU. Oh, almost forgot: we have

padstacks, which can be used a= s pins or pads or vias, and offer arbitrary

convex polygon sh= apes, don't force you to have the same pad shape on all

layer= s. And padstacks support blind/buried vias.)
