Hi Michael.

@You : "...Hi Marco, so the problem is that as I wrote earlier it's far more difficult to write multi-core code than single core code..."

Ok. I really didn't want to start a "philosophical" debate on "why" multi core operation are really a hard thing to treat in the computer science in general.

Anyway, clearly, I agree with you and with your clarification although I already knew these things.

Thanks anyway.
It's always a pleasure for me to talk to you about software developing :)

It's true (unfortunately) that the intrinsic structure of many operation is not easily compatible with a multi core environment and it's really hard to brake their "atomic" structure.

Fortunately there are some kind of operations that, even in a "consumer" software, can be easily crunched by the modern GPU in a "super multi core" fashioned way.

Just to close this interesting topic with a "developing" curiosity...

I don't know if you already know this, but some times ago the guys at "Solid Iris", (the author of TheaRender now aquired by Altair)
were able to create a very efficient UNBIASED render algorithm that runs superfast on both CPU and GPU simultaneously.
This is one of the very rare cases where you can buy a software that will use ALL the computing power of your PC and in this case
for example really worth to buy a superfast multicore CPU and a powerful GPU and you will not waste not even a "penny" :)

I have TheaRender and it's a pleasure to see how it crunches data simultaneously with my i7-7700K and the Gtx 1080 Ti at the maximum speed.

Just a final side note....some times ago I was studying a really interesting programming language called "Erlang", a language that is especially designed
for developing scalable systems. Anyway I think it's not very suitable for developing "desktop" CG software. The unique software that I know that uses Erlang is Wings3D.

Have a nice day and thanks a lot for giving me the chance to talk about these things.

Ciao!

Hi All,

It seems that I was mistaken about the reason for long generation time for my last .nod file.

As it turns out the culprit was excessive number of boolean operations.
By instead using mLoft2 node it was possible to dramatically reduce waiting time.
This substantially more complex form draws to screen in just a few seconds.



James

James,

Respect!
Greate Job!

Karsten

This structure has it's mesh truly intersected ? (no edges ("tubes") intersected)

Karsten,

It hardly needs to be said, but it was your mLoft2 node that resolved it.

Are you working on anything...node-wise?

I don't want to sound like I'm never satisfied, but I was hoping for
a couple of new nodes after to you posted the following:

<<Yep! It seems that we are missing a Network node;-)
And rebuild curve would also help for a complete toolchain!>>

And of course you work on form-finding is beyond my wildest dreams
<<these are the things that drive me>>

So back to you: Respect!
:) James

Pilou,

Can you please rephrase; I don't understand your question.

:) James

Hello James,

At the Moment I don't work on nodes. I've already written a Network node, but it's very unstable caused by the orientation of the Input curves. I didn't figured out how the Standard function solves this Problem. It's the same Problem like the radius factory.
For the form finding I figured out the stability Problem, but it will take some time to solve it. The code is quick and dirty and the biggest issue was the meshing. Maybe I have to rewrite alot of things in it. I'm not a Software developer and in the past sometimes I used C/C++ for short programms. With this Background JavaScript is sometimes a mystery for me.

Have a nice day
Karsten

p.s.:And I have still some private Problems.

As you can see there is no intersection of the material itself! :)

here with 2 grides surfaces intersection but that will be the same with volumes!

a very interesting Scientific comics free books in some subjects of Sciences (Maths Geometry etc...!!! (40 books PDF !!! --- 36 languages )

Hi Pilou,

<<This structure has it's mesh truly intersected ?>>

The grids do not intersect, it is just a pattern mapped to surface of the solid.
If you run the .nod file, you'll see that any appearance of intersection is an
optical illusion in portraying 3d model in 2d image.

Does this make sense?
James

Yes perfectly! :)

Hi James!

Thanks a lot for this amazing node !!

Had some fun with it...

(the 3dm file is pretty big...almost 80MB)

The picture is from a Moi screen export at 3x the original screen size and retouched in Affinity Photo, then scaled down.





Ciao!

Marco (mkdm)

WOW! Marco,

Your graphic is beautiful!
Did you apply subD & shell prior to export to Affinity?

Thanks for sharing
ciao
James

Hi Pilou,

Thank you for the link:
http://www.savoir-sans-frontieres.com/JPP/telechargeables/free_downloads_transit.htm

At first I did not pay the website any regard, because the layout/design is so appalling.
However I did return to it & am glad I did.

It is a wonderful resource, and right up my alley.
My favourite topics delivered for easy consumption (comic form) for the lazy geek.

Thanks again
James

Hi James!

@You : "...Did you apply subD & shell prior to export to Affinity?..."

Oh yeah James!

It took a consistent amount of time to compute on my i7-7700K and I almost get Moi blown up reaching up to 3.5 GB of used memory !!!

:) LOL !

Ciao!

Hi Friends ,
this is an exploration of the various surfaces
Topologically related to that of the Taurus-
I think the Height Torus and some variations are
very interesting
how many interested in the subject find the file available
at this link;
http://www.mediafire.com/file/mbvxj8k8qh688dv/Heigt_Torus_Variation.rar
Good in-depth
Have a nice day to all
best
alberto

Ciao Alberto.

What a wanderful node!!

You rock!!!

I would really like to have your math skill :)

But...unfortunately this wasn't my area of expertise... :(

Thanks!

ASAP I will make some CG elaboration with your node...

Ciao.

Hello,

would someone post Al's last nodefile - Mediafire isn't working for me at the Moment.

Thanks in advance!
Karsten

Hi Karsten.

Here is the file : http://take.ms/kAx7x

It is a modified version of the node based on your indications found in "Deviations.xls" that you posted of some days ago.

It works for me.

Ciao!

Hi All,
I don't know if I'm reinventing the wheel (it can probably be done with the existing nodes)
but I have managed to coded a simple Key Frames node to use for animation.
It as the following features.
1) Inputs: Time, action start and action end.
2) Output: Count and action length.
I'm new to javascript so if someone cares to have a look over it and tell where it can be improved
that would be great.
Many Thanks
Barry

Hello Friends
this my fifth Macro
- Bezier Curves by an open or closed polyline-
it is a great flexibility tool, and I also hope for usefulness
in the drawing

Input:
Open or closed polyline
Output:
Bezier Curve

the file is at this link:
http://www.mediafire.com/file/a6cq469wyhkaq1x/M_-Bezier_Curve_from__Polyline.rar
Have a nice day to all
... (for my friend Marco, thank you for your appreciation )
best
alberto
