| 14:31.17 | brlcad | kanzure: we wrap all 2D into a single 'sketch' entity (which supports points, lines, arcs/circles, and bspline curves) |
| 14:32.07 | brlcad | kanzure: that actually wouldn't be a bad place to start and would be a unique capability by itself (our 2D editing support sucks) |
| 14:33.49 | brlcad | then you could move to 3D implicit entities next (ellipsoids, torii, paraboloids, ..), then the explicit entities last (meshes, nurbs, volumetric data, point clouds, ..) |
| 14:35.04 | brlcad | starseeker: you got me curious |

| 15:48.39 | kanzure | brlcad: where are those 2d primitives and manipulations located? which module? |
| 15:48.58 | kanzure | also are there constraint solving things in brlcad? |
| 15:52.08 | kanzure | yeah, ctypesgen is definitely having a problem with the mingw headers in python-brlcad on windows: https://www.dropbox.com/s/dpy3t0xwwx3gxlv/librt.py |
| 15:52.15 | kanzure | "__time64_t = long long # c:\\opt\\mingw\\include\\sys\\types.h: 49" is invalid syntax |
| 15:53.17 | kanzure | this is re: https://github.com/kanzure/python-brlcad/issues/4 |
| 16:11.07 | brlcad | kanzure: the 2d and 3d entities are in rtgeom.h |
| 16:12.20 | brlcad | rt_curve, line_seg, carc_seg, nurb_seg (mostly unused), bezier_seg, and rt_sketch_internal |
| 16:13.04 | kanzure | ah |
| 16:13.24 | kanzure | brlcad: is there an svg consuming component at the moment? i'd rather just import svg files, or draw using python svg things, and then dump in the data. |
| 16:13.30 | Notify | 03BRL-CAD:n_reed * 58359 brlcad/trunk/src/other/CMakeLists.txt: Hastily stuff dom2dox, an immature tool for rewriting c++ sources with Doc-O-Matic comments to use Doxygen comments, into the tree. The idea is to use it on openNURBS sources. Needs to be integrated, documented, completely rewritten... |
| 16:13.49 | kanzure | actually, i'm sure there's dxf support, so i could just draw dxf.. but yuck. |
| 16:13.50 | brlcad | basically a "sketch" is defined as a set of curves, curves are piecewise composed of lines, arcs, curves |
| 16:14.15 | brlcad | there is no svg component, that's been on a wish list for a while |
| 16:14.28 | kanzure | and constraint solving? |
| 16:14.39 | brlcad | that's under current development |
| 16:14.49 | brlcad | so nothing you can use just yet |
| 16:14.58 | kanzure | alright |
| 16:16.14 | brlcad | and yeah, our dxf-g importer will bring in 2D dxf entities as a sketch |
| 16:16.41 | kanzure | i should just do it using line_seg though |
| 16:16.41 | kanzure | or rt_curve |
| 16:17.00 | brlcad | what do you mean? |
| 16:17.19 | kanzure | well, i was going to use dxf or svg as a cheat to avoid having to implement 2d anything :) |
| 16:17.25 | kanzure | because there are many python svg libraries |
| 16:17.29 | brlcad | sure |
| 16:17.33 | kanzure | and lots of svg/dxf stuff |
| 16:17.36 | kanzure | but it will lose out on brlcad idioms |
| 16:17.45 | brlcad | read in the svg, translate to our data container |
| 16:18.07 | brlcad | http://brlcad.org/wiki/Sketch |
| 16:19.47 | brlcad | basically that page describes how to manually create and introspect a sketch object on the mged command line |
| 16:20.15 | brlcad | you can see how painful it is, but you can also hopefully see how it directly translates to those struct containers |
| 16:20.21 | kanzure | btw the reason i asked about constraint solving is that i would ideally like to make the python api layer in a way that- whenever constraints are working- that i wont need to refactor |
| 16:20.40 | brlcad | mk_sketch() in libwdb takes an rt_sketch_internal object, writes it out |
| 16:20.42 | kanzure | so this probably means object-oriented style geometry construction, with parameters that have signals or call handlers or something. not sure. s/call/update/ |
| 16:22.19 | brlcad | constraints are a complex issue, most cad systems treat them as separate entities |
| 16:22.28 | kanzure | hm! |
| 16:22.43 | brlcad | there are some implicit constraints, that might be more what you're thinking |
| 16:22.45 | kanzure | so you don't "register" constraints on an object? |
| 16:23.14 | brlcad | like if you're modeling a sketch and two line curves coincide an endpoint, that they have an implicit constraint that holds them together |
| 16:23.34 | kanzure | right, and a sphere has an implicit constraint of something something cubed |
| 16:23.50 | kanzure | uh, radius |
| 16:24.04 | brlcad | or in our case, that the three vectors that define the orientation of the sphere are equal in magnitude |
