| 00:46.44 | hcurtis | I am converting some of the elements of BRL-CAD's fast4-g.c from stack allocated to dynamically allocated. Here is the latest version of my code: http://paste.lisp.org/+32BI |
| 00:47.14 | hcurtis | Any feedback is welcome. I can show you my entire revised version of fast4-g.c if you'd like. |
| 00:50.34 | hcurtis | While I wait for feedback, I'll do some reading to refresh my memory on how to make patches. |
| 00:57.13 | hcurtis | By the way, all occurrences of the variable called numberOfRegions in the code I've just posted should say numberOfGroups instead. |

| 01:26.02 | hcurtis | brlcad: Good news. I might be close to a usable patch. http://paste.lisp.org/+32BJ |
| 02:17.12 | hcurtis | I have made a fast4-g.c patch. It might not be usable because I used commit 56495 as my corrections base and will probably need to use commit 60592 instead. At least I know that I am able to do it. My best guess is that I will need to comment out the other person's corrections that Sean disliked, but I will need to confirm this. |

| 09:01.40 | pandrei | hello! |
| 09:02.02 | andrei_ | I was working on the Sketch "Get" implementation |
| 09:02.25 | andrei_ | and I don't understand this |
| 09:02.43 | andrei_ | the Get function is supposed to return a Segment pointer(which I create) |
| 09:03.00 | andrei_ | and gets that from rt_sketch_internal->rt_curve->segments |
| 09:03.03 | andrei_ | which is a void* array |
| 09:04.08 | andrei_ | from what I know, you can't find a variable type in C(and this is not an object) |
| 09:04.48 | andrei_ | how am I supposed to find out what type of segment m_internalp->curve.segment[index] this is |
| 09:08.04 | *** join/#brlcad teepee- (bc5c2133@gateway/web/freenode/ip.188.92.33.51) |
| 09:08.24 | d_rossberg | test the magic and cast the void* to the coresponding structure; there are many examples for this in the sketch code, even in my Sketch.cpp sample |
| 09:08.58 | d_rossberg | use this structure to create the right Line/Arc/etc. class |
| 09:10.30 | andrei_ | oh, I missed the line. thanks |
| 09:12.08 | andrei_ | in the sketch.h you've mentioned I should call Destroy() "after I'm done with it" |
| 09:12.18 | andrei_ | shouldn't I call the constructor in Get and return the objet? |
| 09:12.21 | andrei_ | object* |
| 09:14.28 | andrei_ | ah, nevermind, I think I figured it out. destroy shouldn't be called in get, but after it's no longer needed, and that's not something I need to do |
| 09:19.22 | d_rossberg | you can look at ConstDatabase: there is the same situation with the two Gets (one with a call-back and one returning an object) |
| 09:20.23 | andrei_ | yeah, found it, thanks |

| 12:50.17 | andrei_ | problem is, I can't write the =operator because I can't instantiate Segment |
