18:25.35 callmemrpurpose hello?
18:26.29 callmemrpurpose anyone there?
18:30.05 CIA-4 BRL-CAD: 03johnranderson * 10brlcad/src/librt/g_arbn.c:
18:30.06 CIA-4 BRL-CAD: When an arbn is raytraced, the surface normal reported is whatever was provided
18:30.06 CIA-4 BRL-CAD: by the arbn creator, even if it is not a unit vector. This produces a scaling
18:30.06 CIA-4 BRL-CAD: effect on shading. The prep routine now unitizes the normal vector. This fixes
18:30.06 CIA-4 BRL-CAD: bug #1800161.
18:31.47 callmemrpurpose is this an auto cad room?
18:31.57 callmemrpurpose I have a question
18:32.30 *** join/#brlcad Z80-Boy (i=clock@77-56-76-66.dclient.hispeed.ch)
18:33.21 callmemrpurpose say you are given the number .50x.25 that represents something to do with the angle ofa line. How exactly would you write this in cad?
18:33.37 callmemrpurpose beginner here
18:41.10 Z80-Boy locals only. split.
18:41.22 Z80-Boy No, just joking. What does the 0.5 and 0.25 mean?
18:41.38 Z80-Boy Is it a line whose direction is given by a vector (0.5, 0.25)?
18:52.17 callmemrpurpose I dont know, there is an "X" there also and I have no idea
18:53.32 callmemrpurpose I think it is a line whose direction is given by that.
18:54.19 callmemrpurpose Lets say it is. How, if I already have a starting point, would I enter that vector in cad?
19:09.20 Z80-Boy Hmm I never put a vector into BRL-CAD
19:09.25 Z80-Boy But I know how to put a plane there
19:09.37 Z80-Boy or more precisely a body made from planes
19:09.56 yukonbob callmemrpurpose: it's likely implementation dependant -- in brl-cad to make a cylinder, one indicates a vertex, then the vectors for the endpoint; those are in three dimensions, though, not 2.
19:10.29 yukonbob in mycyl rcc 0 0 0 0.5 0.25 0 0.1
19:10.40 Z80-Boy callmemrpurpose: yeah, you could make a thin cylinder instead of vector
19:10.49 yukonbob where the first set of "0 0 0" == startpoint
19:11.02 yukonbob "0.5 0.25 0" == vectors
19:11.13 yukonbob and last "0.1" == radius of cylinder.

19:12.22 yukonbob regarding autocad and brlcad, though, you'd arguably have a bigger list of differences than similarities.
19:14.17 yukonbob Z80-Boy: are you involved with ronja?
19:14.25 Z80-Boy yukonbob: yes
19:14.57 yukonbob nice -- very cool drawings; are those yours?
19:16.18 Z80-Boy yukonbob: yes

22:03.39 IriX64 heh im a losy gemoetry artist
22:03.45 IriX64 lousy too
22:04.31 yukonbob you can do a table, though -- top, legs, wheels on bottoms of legs.
22:04.53 IriX64 ill think about it :)
22:05.08 IriX64 dinners here ill be back
