Sverchok experiments

nikitron

I wish to start thread with little examples of parametric stuff.

But i cannot upload blend file and 7z file appears fail with status code 413

nikitron

And i cannot edit thread. And remove posts.

Hi Nikita, cool stuff,

@Moult believes open source community should don't edit or delete posts, it helps transparency.

However, many of us are used to edit things most of the times.

Moult

Very cool! I've updated the server to allow uploads. Max file size is 80MB. I'd love to see the Blend files behind this!

I've also enabled editing of posts for up to 1 hour after the post is created. Deletion is still disabled.

It would be good to allow quotation of selection sentences rather than the whole post.

nikitron

i mean, this title post can be extended or butified.

Unic natural phenomenon.

Crickets equidistanced from collective center are generating scalar fields.

Such effect is reachable from sverchok extra nodes, that demand on some python libs, easily installed with sverchok extra extension from Illya Portnov: https://github.com/portnov/sverchok-extra

@nikitron you should totally join us for the next OSArch meetup, and perhaps present next month about your work on Sverchok?

Where can i watch on this meetings?

Zoom or what?

@nikitron is possible share those files since a external website? I am interested in trying.

Very cool! This stuff is awesome! Is there a website with a list of demos that people can download and learn from?

Ok, there are:
1. Examples inside Sverchok (upper example is also there)
2. Presets are also handy
3. Some github themes
4. vk theme
5. gist search can give result

nikitron

Good news.
CNC examples have for now 4 node trees
Among them k40 laser engraver tool preset to export SVG for engraver/cutter. This SVG is ready to cut and you can just plug it on k40whisperer programm. Maybe later on i will make some stuff for youtube on CNC production with Sverchok.

@nikitron have you had time to look at the Geometry nodes from 2.92? I see you keep developing new stuff for Sverchok, does it mean it is going to be developed parallel to Geometry nodes in the long term?

It is parallel, because we install some side stuff and run our core update mechanism. On the stage that GN will be usable i will look at it closely to make interaction.
BUT. GN is only modifier (!sic) for some geometry. It is not fully creating tool, only modifying. On future when blender will be rewritten to use nodes we will forward translation as addon for GN or everything nodes.

ReD_CoDE

@nikitron I asked a question on Geometry Nodes, and I want to share it with you too:
Can we export Blender Nodes (including GN, AN, ...) and Sverchok Nodes into trees/tries and graphs?
All geometry properties and its node properties, ...?

jtm2020hyo

Excuse me @nikitron , could you create nodes for LibreOffice and Gnu Octave? This could a great boost for every FOSS.

What kind of nodes? We have text out and text in for csv json import export. Is it enogh?

we have node remote control for this kind of things. it works with audio nodes, AN, sorcar and we can share this to GN. From side of GN we can manipulate also, but needed some node creation. Not at the moment, but it will be done.
viewer bmesh that creates objects in blender - objects can be modified from GN as usual with exec node modifier assignment. That assignment can be automated later on.

hello @bitacovir, regarding quotes, notice that any line starting with a "more than" symbol are shown as quotes

It would be good to allow quotation

... broken here by my interruption, can be continued by adding a new "more than" symbol

... of selection sentences rather than the whole post.

ReD_CoDE

@nikitron interesting! However, I don't see anything about graphs in your comment

Yes, is cool.

Anything about GNU Octave?

Feel free to add this functions to Sverchok. You can start with scripted node light
But it reads CSV:

https://opensource.com/article/20/2/python-gnu-octave-data-science

input_file_name = "anscombe.csv";
delimiter = "\t";
skip_header = 3;
column_x = 1;
column_y = 2;

@ReD_CoDE said: graphs

I see. there was problems with API. Noone can influence to graphs. We can read it.
