| 03:04.58 | DanielFalck | hi brlcad, it's been quite a while since I have used brlcad. Is it now possible to extrude a dxf path into a solid? |
| 03:05.19 | DanielFalck | using some other program like qcad to generate the dxf |
| 03:19.41 | yukonbob | brlcad: :) |
| 03:21.25 | brlcad | DanielFalck: dxf's with closed-form 2D entities should now import as our sketch primitive |
| 03:22.03 | DanielFalck | ok, great |
| 03:22.07 | brlcad | sketches can be extruded (linearly) |
| 03:22.29 | DanielFalck | is there any way to generate taper? |
| 03:22.31 | brlcad | can't yet sweep them along an arbitrary spline path, though -- that work started this summer but wasn't completed |
| 03:40.34 | brlcad | depends on the shape of the taper and what's being tapered, you could use a separate boolean operation to cut accordingly |
| 03:40.45 | brlcad | alas, extrudes can't be tapered though |
| 03:40.59 | brlcad | at least not via a built-in taper value |
| 03:42.46 | DanielFalck | ok, no problem. thanks for the info |

| 14:26.29 | brlcad | -l is library to link with a preferential order for dynamic then static depending on the platform |
| 14:26.38 | brlcad | you shouldn't ever need to use full paths when linking unless you're doing something really wrong |

| 16:07.08 | kanzure | What's the difference between doing an mged command like "comb dome.c u part1.r part2.r part3.r" and "r mypartname.r u sphere1 sphere2" ? Is it just that g/comb doesn't operate on primitives? Seems like an extra layer of abstraction going on. |
| 16:07.37 | ``Erik | iirc, the onyl difference is that 'r' sets the region flag and 'comb' does nt |
| 16:15.03 | brlcad | kanzure: comb is for creating generalized combinations using any sort of boolean recipe; g creates combinations of only unions; r is for creating generalized combinations that are considered *regions* |
| 16:15.34 | brlcad | kanzure: regions are where something goes from being a pattern/shape/idea to physically occupying space |
| 16:20.27 | kanzure | The tutorial says that regions are just whatever it was before plus some material metadata. |
| 16:20.32 | kanzure | (the mged tutorial) |
| 16:20.47 | claymore | thats correct. |
| 16:21.37 | kanzure | Blah. I don't need tutorials. I need code :-). /me goes back to reading. |
| 16:25.23 | brlcad | kanzure: what's the difference between a blueprint for a car and a car? it's what it was befreo plus some material metadata (i.e. it occupies space) |
| 16:25.56 | clock_ | brlcad: the blueprint starts even in winter |
| 16:26.18 | kanzure | brlcad: Sorry, that doesn't work for me. I'm coming from a programmer's perspective; my "blueprints" usually contain some quite dense information, not just geometric primitives etc. |
| 16:26.29 | kanzure | has a strange background, so the terminology isn't synched yet. |
| 16:27.06 | brlcad | kanzure: one is an "idea", one physically occupies space -- organizationally, they're is no difference |
| 16:27.30 | ``Erik | just a 1 bit flag :) |
| 16:27.30 | brlcad | from a programmer's perspective, it's literally a boolean flag that is set |
| 16:27.35 | kanzure | Maybe it would help to know what other commands do when the region flagged is set/unset. |
| 16:27.44 | brlcad | but that flag changes the way things behave -- where overlaps exist |
| 16:27.48 | kanzure | ah? |
| 16:28.30 | brlcad | akin to "shape" vs solid |
| 16:29.25 | kanzure | So, I can (uselessly) have a shape that intersects itself, but if a region/solid had that sort of configuration it would be invalid? Is that's what's going on here? |
| 16:29.43 | kanzure | *intersects and goes through itself in a physically impossible manner, to be more precise |
| 16:30.09 | brlcad | right |
| 16:31.19 | brlcad | before it's a region -- if you union two objects together, it's the union of the sets they represent -- if it's a region and one is steel overlapping another object that is wood, that's invalid since you have two materials occupying the same space |
| 16:35.25 | kanzure | Neat, 'tree' shows me a boolean algebra tree. If I modify one of the primitives at some ridiculous depth in the hierarchy, is the entire tree modified, or is there a way for me to do versioning control on it? |
| 16:36.55 | brlcad | I don't know what you mean by the entire tree being modified, but there is no automatic versioning control |
| 16:37.02 | brlcad | at least not yet |
| 16:37.30 | brlcad | one of the features of the new geometry service is to provide automatic versioning control on all edits, comprehensive tracking |
| 16:38.14 | brlcad | or by versioning control, do you mean instantiation .. you have 20 crayons in a box and you want to make one have a bite taken out of it |
| 16:38.24 | brlcad | that's easily doable |
| 16:38.26 | kanzure | I think that's nearly the same thing |
| 16:38.56 | kanzure | that second case, of 20 crayons + a bite taken out could be done via copying the tree, but maybe I'm lazy and I do something "irreversible" and harm my precious tree |
| 16:39.05 | kanzure | I guess you already answered that though, it's generally irreversible at the moment :) |
| 16:39.08 | brlcad | no no, not at all the same thing -- by versioning control, I'm talking SVN/CVS style complete revision history of all edits |
| 16:39.23 | kanzure | yes me too, but I was thinking of an object-level for versioning control, not for the entire file. |
| 16:39.41 | brlcad | I mean per object too |
| 16:39.54 | brlcad | instantiation is a much different beast though |
| 16:40.43 | brlcad | in y our example, you could create a copy of the tree -- there are shallow (referential) copies and deep copies you can perform |
| 16:41.16 | brlcad | if you wanted to be safe, you could make a deep copy and do whatever you wanted, the original tree would be unmodified (as there is no association after the deep copy) |
| 16:41.22 | kanzure | but if I don't make a copy before I make a modification to a very integral component, then the overall tree is modified, even before I ask for the new tree to be recomputed? |
| 16:41.30 | brlcad | if it's a shallow copy, then it depends on the edits performed of course |
| 16:44.54 | brlcad | there is no "recomputation" that occurs, everything is instant -- but if I understand you correctly -- yeah, if you make a change, it's changed ;) |
| 16:45.18 | kanzure | ok, instant change propagation and such. |
| 16:45.34 | claymore | One must unlearn what they have learned... for there is no spoo..err, undo. |
| 16:45.39 | brlcad | much like the unix command line, very unforgiving -- modelers using the command line are expected to learn/know the implications of the various commands |
| 16:46.15 | brlcad | make copies of your .g when you're first getting started ;) |
| 16:47.30 | brlcad | kanzure: it's not so much that it propagates, either -- think of how the CSG hierarchy is stored in memory, it's a graph of nodes -- all you did was change a node, nothing to propagate/recompute |
| 16:47.55 | brlcad | something like the "tree" command just walks the graph and prints it while it walks |
| 16:48.52 | kanzure | right, and frankly I prefer the shell :) none of this engelbart mouse nonsense. |
| 16:50.17 | claymore | there are a few tasks in mged that can be accomplished *MUCH* faster via use of gui/mouse. The reverse is also true. Its a nice balance really :) |
| 16:50.45 | kanzure | Clicking a few thousand times with a mouse can get dull. |
| 16:51.31 | claymore | true dat. |
| 16:58.48 | DanielFalck | brlcad: I'm looking for a non-64 bit binary for linux on sourceforge- I don't see one |
| 16:59.10 | kanzure | DanielFalck: I ended up compiling one for myself the other day. |

| 16:59.52 | DanielFalck | ok, will do |
| 17:05.38 | brlcad | DanielFalck: look at the previous releases |
| 17:06.03 | DanielFalck | I found 7.10, but I think I'll build from svn |
| 17:06.08 | brlcad | a version or two earlier should work just as well unless there's some specific feature you know you need |

| 17:06.30 | brlcad | should have another release up shortly |

| 17:56.32 | DanielFalck | it's making right now |
| 18:00.01 | kanzure | Is there a way for me to serialize everything I've done into a set of commands and scripts? |
| 18:00.40 | kanzure | ah, I guess just having the .g file means I can go back and modify objects with a script, so nevermind |
| 18:01.37 | kanzure | was writing a filter generator in python a few weeks ago that generated STL files, to link up to OpenFOAM for CFD, but this is looking like a better deal :) |
| 18:01.59 | brlcad | yeah, or if you run g2asc, it'll turn it into an "mged script" i.e., a brl-cad database in ascii form |
| 18:02.17 | kanzure | Thanks. |
| 18:03.09 | brlcad | mged itself is pretty heavily scriptable in a variety of ways too, an example of a few of them at http://brlcad.org/wiki/SGI_Cube |
| 18:03.58 | kanzure | yeah I found that page a few moments ago when I was about to start complaining about Tcl (I've been able to avoid it so far, you see) |
| 18:06.44 | brlcad | basically amounts to mged supporting single-command invocation, commands over piped or redirected input, commands loaded via the 'script' command, or a serialized subset using the ascii storage format |
