| 00:59.30 | brlcad | starseeker: nice link |
| 00:59.58 | starseeker | was poking around looking for stuff to help Richard |
| 01:00.26 | brlcad | he's stuck? |
| 01:00.39 | brlcad | he's certainly stopped committing |
| 01:01.07 | starseeker | he's looking for a really robust line-line intersection routine (or more correctly, closest distance between two 3D lines) |
| 01:01.18 | dli | brlcad, I'm reading the files in src/pro-db, need more time for understanding, but I can see the complexity of work done is still quite light, like 2,000 lines to me |
| 01:01.33 | brlcad | starseeker: and libbn's is insufficient? |
| 01:01.39 | starseeker | apparently |
| 01:02.07 | starseeker | he wasn't set up to take me through all the details tonight |
| 01:02.12 | dli | brlcad, also, the idea of "self-healing" I mentioned was already there, "linear perturbation" in the poster link you posted |
| 01:02.58 | brlcad | starseeker: if ours isn't sufficient, then he should be able to characterize how/why and fix it .. not duplicate the code with another function |
| 01:03.23 | brlcad | validating ours against an algorithm would be cool, but definitely shouldn't just be snarfing in another function |
| 01:03.46 | brlcad | rewriting ours would even be fair game -- that's the point of the testing framework |
| 01:03.49 | starseeker | nods - he can't do that with that link anyway, that's C++ code |
| 01:04.38 | dli | brlcad, I need to understand how it works now, then, I will try to see what is a good approach from here |
| 01:04.41 | starseeker | I think he's identified come failing test cases but isn't sure what to do to fix them |
| 01:04.48 | brlcad | http://www.geometrictools.com/Documentation/DistanceLine3Line3.pdf isn't c++ |
| 01:05.10 | starseeker | true - I sent him that link to see if it would help |
| 01:05.26 | brlcad | dli: sounds good |
| 01:05.58 | brlcad | dli: I'd hope it's not too heavy .. then people's brains shut off and they tend to start from scratch |
| 01:06.17 | brlcad | wasted effort |
| 01:07.22 | starseeker | I just ment he couldn't snarf the geometrictools code directly - he'll still need to figure out how to do it in our code |
| 01:07.47 | dli | brlcad, should be fine, I expected like 10,000 lines, it's not that bad, 2,000 lines, if comments not counted, and rewrite in C++ style (now, it's like C style C++), my guess is like 500 lines, fair for me to start |
| 01:09.58 | brlcad | dli: note that's just one function you're working on -- there's several other routines that will be needed later :) |
| 01:11.51 | dli | brlcad, okay, I will concentrate on that part |
| 01:12.33 | brlcad | surface,surface->curve is really surface,surface->surface|curve|point .. which is really also a parent case of surface,point->point + surface,curve->curve|point + surface,surface->surface|curve |
| 01:12.57 | brlcad | at least when you consider the grazing cases |
| 01:14.59 | dli | brlcad, I added this to my note, talk to you later |
| 01:30.19 | starseeker | huh http://code.google.com/p/poly2tri/ - I don't recall stumbling on that before |
| 01:35.50 | starseeker | this one too http://www.netlib.org/voronoi/hull.html |
| 03:50.40 | brlcad | the first is interesting, but doesn't look too much different than our current triangulation |
| 05:06.54 | CIA-62 | BRL-CAD: 03brlcad * r43209 10/brlcad/trunk/doc/deprecation.txt: SMALL was deprecated a long time ago, but is a minimally impacting change |
| 05:08.38 | CIA-62 | BRL-CAD: 03brlcad * r43210 10/brlcad/trunk/include/vmath.h: |
| 05:08.38 | CIA-62 | BRL-CAD: provide a ZERO() macro that corresponds with the EQUAL() macro. tolerance is |
| 05:08.38 | CIA-62 | BRL-CAD: defined at compile-time so it's not the best to use, but still more reliable |
| 05:08.38 | CIA-62 | BRL-CAD: than exact floating point comparisons. it'll also permit cleaning up numerous |
| 05:08.38 | CIA-62 | BRL-CAD: NEAR_ZERO() callers that arbitrarily use SMALL, SMALL_FASTF, and |
| 05:08.39 | CIA-62 | BRL-CAD: SQRT_SMALL_FASTF when the intent is just a nearness to zero. |
| 05:25.50 | CIA-62 | BRL-CAD: 03brlcad * r43211 10/brlcad/trunk/src/libbu/units.c: convert from NEAR_ZERO() to ZERO() |
| 05:26.54 | CIA-62 | BRL-CAD: 03brlcad * r43212 10/brlcad/trunk/src/libbn/ (9 files): lots of conversions from NEAR_ZERO() to the new ZERO() macro where the tolerance test is merely against SMALL_FASTF or used to test for zero-division. |
| 05:28.06 | CIA-62 | BRL-CAD: 03brlcad * r43213 10/brlcad/trunk/src/anim/ (anim_fly.c anim_hardtrack.c): start of larger covnersion over to new ZERO() macro. |
| 05:34.27 | CIA-62 | BRL-CAD: 03brlcad * r43214 10/brlcad/trunk/src/librt/ (49 files in 24 dirs): convert from NEAR_ZERO() to ZERO() where SMALL, SMALL_FASTF, and sometimes even where SQRT_SMALL_FASTF is used. simplify. reduction also made where intent seems to be a zero-test for a subsequent division. |

| 15:17.45 | CIA-62 | BRL-CAD: that look legit, lot of adding of UNUSED and removal of self assignments - if |
| 15:17.45 | CIA-62 | BRL-CAD: there was a reason to avoid UNUSED in these cases will have to revert and try |
| 15:17.45 | CIA-62 | BRL-CAD: something else. Somewhat mysteriously, bu_byte_offset didn't cause a compiler |
| 15:17.45 | CIA-62 | BRL-CAD: failure - that's probably incorrect and we still need to do some sort of #if |
| 15:17.48 | CIA-62 | BRL-CAD: defined(__clang__) specific logic there. |
