Hi Michael,
>> I'd need to have an actual running example that I could test with over here, that would then enable me to profile it and see where most of the time is going.
It will be great if you implement object instances in new version of MoI. At the moment we need to run Clone factory for each object instance. Unfortunately this method is not fast enough.


P.S. Double click on background to show execution times of nodes.

Hi Max.

Thanks a lot for this example!

Cloning it's just one of the things that I had in mind :)

If I remember correctly right from the very first days of V4 announcement these were the "cornerstones" we ever agreed on :
1) 64Bit
2) Instancing
3) Grouping

I'm confident that during the V4 beta period Michael will give us 2 and 3 also :)

Ciao!

At some point I'd like to focus more on that. But unfortunately there's a lot of work involved especially detailed and time consuming support work for focusing on that area. One of my biggest limits in being a single person company is how much support is required by what I'm trying to do.

I should be able to make some progress though.

Thanks Michael for sharing.

@You : "...being a single person company...I should be able to make some progress though..."

I'm confident that you're doing your best :)

Thanks a lot for your support and best wishes for all your things!

Ciao.

Hi Max, yes instancing should help with making larger numbers of copied objects.

There is a kind of lightweight instancing built into the Transform factories currently, but it will only kick in if the factory is generating more than 1000 curves or more than 50 (setting from ProxyGenerationNumFactories in moi.ini) faces total. Also it's built around the regular transform commands where there's only one factory generating stuff and so when the command finishes it wipes out all proxies and not just the ones it made.

But I think it would not be difficult for me to refine this mechanism a little bit to give you a way to do a type of "preview mode" where you'd be able to generate a display of a lot of object copies more quickly.

That would be able to happen pretty soon, the full instancing is a bigger chunk of work.

Hi James
from now on, I worked using updated Karsten's NE,
but I still have many files to share with you, all made with previous versions of the latest update ....
so the advice I give you is to create a double folder, one with them
Old Extension and One with NE ...
in this way, you can open it from time to time, compatible Elephant
with everything....
Thank you for appreciation
Have a nice day
alberto

Hello Al,

good news! Please tell me: Are there problems to convert the files?

Thank's in advance
and have a nice day
Karsten

Hi Karsten (and others),

Attached is a file with macro that converts a Brep to Edges & points.



I have tried modifying your "Extract" node by making line 212 & 217-220 into comments so that it only outputs edge curves. It works perfectly however is no use for the sharing of .nod files, & hence convert.nod attached.

I wonder though, if it would be difficult to add an "Edges Only" option to your node. Perhaps, if this could be included, it might be an opportune time for a name change (to let's say "Derive"), so as to remove the redundancy of 2 nodes of the same name & not be confused with Max's Basic/Extract.

Anyway, this was just a thought

Have a great weekend
James

EDITED:
Better still, might be for Max to fold this functionality into a Brep option in his "Exract" node

Hello James,

what a surprise. I didn't planed to use the node in this way. It is pure coincidence, because no names are stored in the node and no names are given to the input. Typically it should be used in combination with the brepNameSubObj. So the node stores pre-selected names and filters it while running. I think there are different possible ways to solve it. You have already shown a way. Nevertheless it would be great when Max would integrate it in the next release of his extract node.
Brep - option on RMB and a filter/switch for edges and faces.

Have a nice day
Karsten

Hi Karsten

Thank you for getting back to me.

Can you tell me is Objects2/separateObj effectively identical to Objects2/Extract if it had a "Faces only" option?


Geometrical world trip: Welcome to Bruxelles:-) ??????
James

Hello James,

The seperate node is identical with the separate command in moi - same factory. It smashes objects. Joined curves in segments, solids and joined surfaces in single faces.

Have a nice day

RE:Atomium...Ahh now I get you

RE: SeparateObj
Cheers, thanks for info

Hi,
how can I enter an adjustable range ( from calcs using maths nodes ) into the points node other than with the range slider.
Cheers
Barry

Hi Barry,

<<enter an adjustable range.... other than with the range slider>>

Use objects2/concat2 node, with RMB option Numbers



Let me know if you need further clarification

James

Hello Barry,

of corse, you can. Start and end value can be calculated independent from each other. Then you have to concate them together as input for the points node.
Concate2 node can take numarray, pointarray and objects as input (RMB).

Have a nice day
Karsten

Hi James,
thanks can't tell you how long I've messed about trying different permutations.
Not sure if my memory is correct but did Karsten do a spreadsheet with node definitions on it ?
Cheers
Barry

Hi Barry

Spreadsheet can be found here:

Hi James.

Thanks you very much!
This is a very useful nod file!

Ciao!

Hi Marco (& others),

<<This is a very useful nod file!>>

Assuming you are talking about "convert.nod",
you may prefer to do what I have done,
which is to include new node in "objects2"
called "ExtractEdges"

It is simply Karsten's "Extract" node minus a few lines of code.

It achieves the same effect as convert.nod edges output
without issues that arise with multiple inputs & poly-surfaces.

Maybe you could look at it's code.
It is at the very end of the script.
I suspect that several more unnecessary lines
may be removed (or made into comments)


James

Hi James.

Thanks a lot for the "ExtractEdges" new node !

I will be very useful also for my "2D workflows" :)

Asap I'm going to look at its code.

Thanks!
