| 00:54.43 | CIA-28 | BRL-CAD: 03starseeker * r34368 10/brlcad/trunk/src/libged/tire.c: Try a different approach to getting the trimming cyl height for tread side clipping. |
| 00:55.09 | starseeker | ``Erik: see what that does for your tire dimensions |
| 00:55.35 | starseeker | here it seems to at least produce something reasonable, although I'm sure the tread is still not up to your standards |
| 01:00.37 | starseeker | begins to understand the fundamental limit on the tall and narrow tires - beyond a certain point, even the elliptical torus becomes self intersecting at the origin |

| 01:25.50 | starseeker | brlcad: So the best way to count size is to figure out how much information is required to store the minimal number of parameters necessary to represent the various primitives, and then count? |

| 02:40.17 | starseeker | brlcad: I see the report of faces as part of the opennurbs object summary, but it's not immediately clear how much information is really needed per face |
| 02:40.36 | starseeker | what's the best way to estimate something like that? |
| 02:41.19 | starseeker | each trim seems to need a fair bit of info, and the number of trims per face varies |
| 02:51.50 | starseeker | anybody know how to edit bots in mged? |

| 03:26.23 | starseeker | attempts to work around the issue... |
| 03:27.26 | starseeker | <grin> tire creation in Rhino: http://www.toxiclab.org/tutorial.asp?ID=122 |
| 03:50.24 | starseeker | grr. ok, that's enough failed tesselations for one night. :/ |
| 04:07.21 | brlcad | starseeker: there have been a few sketch changes but nothing that should affect a RT_SKETCH_CK_MAGIC check |
| 04:14.50 | brlcad | and yes, you need a basic 'value' count per primitive type -- the implicits are a constant, bots are minimally constant*numfaces, sketches are (minimally) count of 2d points plus 4 |
| 04:15.02 | brlcad | e.g., eto looks to be 11 values |
| 04:17.31 | brlcad | a sphere would be 4 or 6 or 12 depending on how you count |
| 04:17.44 | brlcad | (4 for the sake of the poster) |
| 04:19.10 | brlcad | i think bots are simply 9*numtriangles |
| 04:23.42 | brlcad | for nurbs 'faces', if you find the approximate face count, we can probably determine a minimum bound (e.g., 12 per surface) |
| 04:25.02 | brlcad | you should be able to approximate the surface count |
| 04:25.20 | brlcad | (without having an actual count) |
| 05:08.08 | starseeker | counted faces for nurbs |
| 05:08.48 | starseeker | around 2562 |
| 05:09.28 | starseeker | for the default treaded tire |
| 05:10.21 | starseeker | assuming you don't break the tire surface up into individual chunks due to the tread |
| 05:12.44 | starseeker | the implicit model I'm coming up with 916, not counting the extrude needing the sketch name, the matricies used to rotate the tread pattern around the tire, or the combination storage |
| 05:13.50 | starseeker | triangles... I've got 2684 faces for the wheel, 11902 for a non-treaded tire (no wheel) and I'm still working on the tread |
| 05:14.36 | starseeker | should be easily over 20000 |
