| 02:08.59 | abetusk | for { set i 1 } { i <= 5 } { incr i } { |
| 02:09.00 | abetusk | echo $i |
| 02:09.00 | abetusk | } |
| 02:09.21 | abetusk | gives: Error: invalid bareword "i" in expression " i <= 5 "; should be "$i" or "{i}" or "i(...)" or ... |
| 02:09.25 | abetusk | help? |
| 02:09.47 | brlcad | abetusk: what don't you understand? |
| 02:10.12 | abetusk | What the proper syntax is |
| 02:10.26 | brlcad | abetusk: the "i" in "i <= 5" is invalid |
| 02:10.34 | brlcad | it gives you suggestions |
| 02:10.40 | abetusk | substituting $i does not work.. |
| 02:10.40 | brlcad | what's the first suggestion? |
| 02:10.47 | brlcad | what does that do? |
| 02:10.56 | abetusk | it does not print out anything |
| 02:11.06 | brlcad | that's a different problem |
| 02:11.06 | abetusk | but runs without error |
| 02:11.10 | abetusk | true |
| 02:12.39 | brlcad | where are you running that script? |
| 02:13.06 | abetusk | I have a an mged command line window open |
| 02:13.11 | abetusk | is that what you're asking? |
| 02:13.37 | brlcad | yep |
| 02:13.42 | brlcad | change echo for puts |
| 02:14.14 | abetusk | thank you |
| 02:14.20 | abetusk | what is the difference? |
| 02:15.37 | brlcad | the tcl intepreter running within mged is running within a complex I/O framework |
| 02:16.17 | abetusk | Right, tcl. Haven't used that in over a decade. |
| 02:16.35 | brlcad | tcl's default behavior for commands doesn't output to channels we control -- we override the behavior for puts so it works, but not for echo |
| 02:17.01 | Skriptkid | brlcad: Where is SSE being used? Libbu? |
| 02:18.29 | brlcad | Skriptkid: grep _SSE include/* |
| 02:19.05 | brlcad | vector_x86.h in particular iirc |
| 02:20.57 | Skriptkid | Thank you. |
| 02:21.41 | brlcad | if you follow the preprocessor symbols and functions, those are part of a general interface used in a few places, but src/librt/test_dvec.cpp and src/libnurbs/opennurbs_fit.* come to mind |
| 02:22.34 | Skriptkid | I'll look at them too. |
| 02:23.38 | brlcad | the dvec interface is generalized |
| 02:24.01 | brlcad | it presently toggles over between vector_x86.h and vector_fpu.h depending on whether sse is available |
| 02:24.23 | abetusk | is there a way to 'select' the object from the command line instead of from the 'primitive selection' dropdown? |
| 02:25.33 | brlcad | skriptkid: instead of compile-time toggle, the goal is to make it toggle at run-time (several ways to do that) |
| 02:25.48 | brlcad | Skriptkid: but definitely not easy - don't bang your head for too long |
| 02:25.52 | Skriptkid | So that toggle needs to be done during runtime rather than at cMake. |
| 02:26.17 | brlcad | abetusk: absolutely, you can use the sed or oed commands to select primitives and combination objects |
| 02:26.21 | Skriptkid | Oh. I might need an extension. I haven't been able to work on it yesterday. |
| 02:26.31 | brlcad | Skriptkid: no worries |
| 02:26.55 | brlcad | abetusk: e.g., make sph sph; sed sph ; tra 10 0 0 ; accept |
| 02:27.29 | brlcad | or: r sph.r u sph ; oed / sph.r/sph ; tra -100 0 0 ; accept |
| 02:27.57 | brlcad | oed's a little tricky, but there's an entire tutorial on it on the website |
| 02:29.02 | abetusk | brlcad, I appreciate the help. I learn faster this way. As long as you can stand it, I would like to ask this way. |
| 02:31.13 | brlcad | abetusk: sometimes it takes seconds to respond, sometimes hours, but I always respond and absolutely don't mind |

| 05:58.16 | yukonbob | Anybody aware of brlcad being used for data visualization outside of CSG modeling or displacement maps? Examples? I'm aware of DSP for viewing eg USGS DEM data, and modeling objects for various illustrative purposes (show design, construction, measure mass and dimensions), but curious what other creative uses have been performed. |
