| 00:20.36 | brlcad | yep! |
| 00:20.49 | brlcad | looks like it's quite usable, I have to do some more testing |
| 00:23.46 | konrado | Thank, good to know |
| 00:24.28 | konrado | Would brlcad be applying for gsoc this year ? |
| 00:32.01 | brlcad | have not yet decided |
| 00:34.38 | konrado | Ok |
| 00:34.44 | konrado | Is it possible to make uses of brlcad primitive like box and sphere instead of creating polygon |
| 00:38.31 | konrado | My doubt are actually getting proper orientation along with the other vrml polygonal representation |
| 00:40.37 | konrado | I have come across such representation within blender |

| 00:41.44 | konrado | but the orientation was not proper and some primitive were not supported |
| 00:50.18 | brlcad | konrado: absolutely -- you should create box and spheres ... if you can detect them :) |
| 00:50.49 | brlcad | detecting them can get pretty hard though in the general case, ask starseeker as that is exactly what he's working on right now |
| 00:51.08 | brlcad | he might be able to provide some functions you could use.. good testing |
| 00:53.03 | konrado | detecting them withing vrml file? |
| 00:55.27 | brlcad | that is what you said |
| 00:55.51 | brlcad | starseeker's routines could also simply run as a post-processor if he gets it all working |
| 00:56.20 | brlcad | but if there's some indication within the vrml format that something is a box or other shape, that'd be a better place |
| 00:57.32 | konrado | here is the example file i used for the snowman with mainly primitives http://pastebin.com/UyntJhjx |
| 00:59.19 | brlcad | can't get to pastebin.com from here (there are better pastebin's) |
| 01:03.12 | konrado | It the vrml-g converter read the primitive and get the primitives and their dimensions then does the splitting to polygon |
| 01:03.20 | konrado | link https://drive.google.com/file/d/0B8_3Ywn_DeDFMjk4c1puUGpvSms/view?usp=sharing |
| 01:06.17 | brlcad | heh, also cannot get to drive from here, but will check that out later |
| 01:09.04 | konrado | Just be sure I am not getting you wrong what do you mean by detecting the primitives |
| 01:09.12 | konrado | ? |
| 01:10.46 | brlcad | if they're already primitives in the vrml format, then you have your answer..... |
| 01:11.27 | brlcad | a sphere is a primitive, a box (a right-parallel piped aka rpp aka arb8) is a primitive, a torus is a primitive, ... |

| 01:12.11 | brlcad | so if vrml knows "sphere" and defines it as a point and a radius or something similar, then ABSOLUTELY you should be creating a sphere in brl-cad, not turning that sphere into a set of triangles |
| 01:12.18 | brlcad | mk_sph() :) |
| 01:12.33 | brlcad | mk_*() ... see include/wdb.h and include/rtgeom.h for all our entity types |
| 01:14.03 | konrado | This is how sphere not for the snowman is represented |

| 01:14.07 | konrado | <PROTECTED> |
| 01:14.07 | konrado | <PROTECTED> |
| 01:14.07 | konrado | <PROTECTED> |
| 01:15.41 | konrado | It start making the changes to code as soon as possible |
| 01:18.37 | konrado | The node are read and stored using a directed graph data-structure and they are retried using a depth-first search |
| 01:31.34 | konrado | I would need some help scaling getting orientation of the primitive right |
| 01:42.42 | konrado | brlcad: Thanks again for the directives. It has clarified some of my doubts and I am also learning a lot while working on this project. |
| 01:44.42 | konrado | Need to get some sleep :) |
