"I've did some tests compiling a rhino 5 to rhino 4 backwards conversion tool; which worked quite fast and easy with adapting 3 lines of code. I used the instructions placed…"

"Cool, I'll have to check it out. Sounds like there is a lot of potential here."

David Rutten replied to Kendra byrne's discussion RhinoCommon access outside of Rhino visual environment

"Many parts of RhinoCommon rely on the Rhino C++ SDK, which is only available while Rhino is running. However as Jon pointed out, we have a special build that doesn't include any of the Rhino-specific stuff and this can be used as a…"

Jon Mirtschin replied to Kendra byrne's discussion RhinoCommon access outside of Rhino visual environment

"Here's my understanding (I haven't tested explicitly yet but plan to do so ASAP). I'm not sure if you're studied openNURBS, but it's the dotNET framework used in Rhino v4 (and earlier) that could be accessed outside the…"

RhinoCommon access outside of Rhino visual environment

Is RhinoCommon available to use as a library outside of the Rhino visual environment?If it was, it would open up the potential for the development of "Rhino powered" applications, which could be a powerful alternative to something like OpenFrameworks for comprehending geometry.It sounds like the idea may have been on the roadmap a while back.See More

"There's also the general Python copy functions. However I believe that those methods (particularly deepcopy) may be slower than what we've already covered, at least for lists.:D"

"Interesting! I didn't know that list() makes a copy of the list. I was only using it to convert tuple to list! Thanks Anders for posting. PS: Do you have a Python cheat sheet somewhere on your blog? You should post one if you haven't done…"

"In continuation of that, I'm not really sure if any memory benefits of modifying lists in place outweighs the potential problems this may cause (i.e. losing track of what's what ID-wise). It would be interesting to examine this more…"

"Got it. I should have mentioned that my most recent post was a more general observation of list behavior in python."

Mostapha Sadeghipour replied to Kendra byrne's discussion speed questions

"Kendra, What I was trying to say is how lists work in Python. My understanding from your description was that you see the changes in the original list that you don't want to happen. Is that right? What I mentioned above is why this is…"

"Thanks Mostapha, part of a generation of home schooled coders here. So, let's say I have a list of numbers called numberList, and I then pipe numberList through a definition that adds the value 2 to each number in numberList. From…"

Mostapha Sadeghipour replied to Kendra byrne's discussion speed questions

"Kendra, What you get is normal since in python both lists are referring to the same place somewhere in the memory (they are the same list!). You should make a new copy of the list if you want the changes not to effect the first list.…"

"That's all great to know, David, thank you for the post. I will look into the stopwatch class and see what I can learn. Is there also a way to keep track how much memory your using per definition or per array? I did run into an unusual…"

"If you are using the Rhinoscriptsyntax library this may substantially slow things down as compared to straight up RhinoCommon (see this thread). Beyond that it sounds like you might also have some "logical errors" in your scripts which are…"
