11:17.39 *** topic/#brlcad is BRL-CAD || http://brlcad.org || logs: http://ibot.rikers.org/%23brlcad/ || GCI winners: Jacob Burroughs and Peter Amidon! || GSoC 2014 selections are announced! Thank you to all we got to work with. Remember that SOCIS is coming up right around the corner and you don't need a summer of code to get involved with open source.

13:07.35 starseeker brlcad: OK, if we're going to leave poly2tri as an external lib/algorithm rathern than "borg" it into our C libraries I can see that. However, that makes it *imperative* that someone who knows what they are doing with C++ error handling fix poly2tri the right way
13:07.49 starseeker which I freely admit is not me
13:08.42 starseeker I can try, but I'm starting from square one and the stakes are very high from a user perspective
13:28.37 Notify 03BRL-CAD:starseeker * 62392 (brlcad/trunk/doc/docbook/system/man1/en/g-tankill.xml brlcad/trunk/doc/docbook/system/man1/en/g-var.xml): xmllint fixes
13:28.44 Notify 03BRL-CAD:starseeker * 62393 brlcad/trunk/src/librt/primitives/hrt/hrt.c: set but unused error
13:47.36 Notify 03BRL-CAD:starseeker * 62394 (brlcad/trunk/src/other/poly2tri/README.md brlcad/trunk/src/other/poly2tri/poly2tri/common/shapes.cc and 8 others): All right - if we're going to keep poly2tri separate as opposed to eventually merging it into BRL-CAD's libs (and the work the bitfighter folks are doing combining clipper and poly2tri suggests that's a good idea) then we shouldn't be ripping out references for pointers.
13:47.39 Notify We need another way to make the error cases do something other than bring down the application.

17:41.14 pujaniS sir what is meaning of VGR?
17:41.27 pujaniS what is the use of VGR?
17:42.05 pujaniS VGR is any speed, running time or any thing else?

18:22.13 gurwinder brlcad: hello
18:24.13 gurwinder I want to export only x coordinate, which we get using (ell->a). But I want only x value of 'a' I searched in ell.c. But can't get appropriate solution. eg. in pov ray, sphere is give by center and radius. center is exported succesfully but radius not. (ell->a) gives x, y, z but i want only x.
18:26.21 gurwinder brlcad: sorry for mistake. We get x, y, z values using (ell->a) in case: ell. I want only value of x

20:48.42 brlcad starseeker: the ptr vs ref is completely irrespective of being snarfed in and borgified. c++ added refs because it explicitly makes one entire category of crashes disappear. the issue really is just how to 1) not let poly2tri decide when to halt an application and 2) how to let the callee know when something is wrong
20:48.58 brlcad removing the aborts is good for #1
20:50.56 brlcad could have also left the aborts and used sigaction() if we needed/wanted to keep them pristine
20:52.15 brlcad the more complicated of the two issues is #2, as there are many possible options
20:54.53 brlcad setting an int or enum code is probably the very simplest change possible, but then looking at the code, that may even already be happening, so removing the aborts/asserts (or setting up handlers) may be sufficient
23:33.55 clock brlcad, is there some paid job on brl-cad which can be done remotely by a non-us national%
