| 18:34.17 | brlcad | starseeker: i'm working on a fix |
| 18:34.57 | brlcad | really need a way to set the tolerance, but that's an old API |
| 18:36.43 | brlcad | so I can either underlay a new set of calls that support tolerancing.. (with the old calling the new with the old tolerances), punt and mod the API with an additional parameter, or make libbn tolerancing stateful with a getter/setter to mod it |
| 18:37.32 | starseeker | is the cleanest way to mod the API? |
| 18:37.49 | brlcad | of course :) |
| 18:37.55 | starseeker | votes for that way |
| 18:38.07 | brlcad | the first is clean too (eventually), just takes a lot longer |
| 18:38.53 | starseeker | but once the calls supporting tolerancing are in, the ones without it become unnecessary except to support code that hasn't been updated, yes? |
| 18:42.19 | brlcad | right |

| 18:42.40 | CIA-28 | BRL-CAD: to a working state. there are v4 stored matrices that are within default |
| 18:42.40 | CIA-28 | BRL-CAD: computation tolerance (0.0005 -- actually around 1.0e16), but not nearly tight |
| 18:42.40 | CIA-28 | BRL-CAD: enough for SMALL_FASTF's 1.0e-77. still failing star regression though. |
| 18:42.48 | brlcad | wouldn't be able to remove the old api for about a year |
| 18:42.58 | brlcad | (3 minor releases) |
| 18:43.28 | brlcad | though arguably, there would be an alternative .. so could deprecate and remove after one release |
| 18:44.43 | starseeker | indeed - that fix should be quite simple for any external breakage - just stick in the previous hard coded default and the behavior becomes identical |
| 18:45.59 | brlcad | star is interesting.. just 75 pixels off by many |
