Interesting.
Are you the developer of Sverchok?

Yes, I am.

Use it from GIT, current version much newer, than v0.2.0

Here what it doing:

Nice work. And nice to hear Blender joined the visual programming crew.

You even named it 'Grasshopper'... way to be subtle about it :)

I'm sorry but that's just not cricket :)

'You should consider that Imitation is the most acceptable part of Worship, and that the Gods had much rather Mankind should Resemble, than Flatter them' Marcus Aurelius 

or rather

'Imitation is the sincerest form of flattery'

I was just going for the play on words as Sverchok is Russian for cricket :) 

I think David has openly maintained that others will come along and it his responsibility to stay ahead of the game.

Competition is always catching up, that’s its job. You won’t defeat the competition by flailing around and yelling “Mine!”. The only way to get on top is to write better code than the competition and the only way to stay on top is to keep writing better code than the competition....

@Nikitron,

I like your approach to transparency of Nodes allowing the user to see manual settings and outputs at a glance. All thought I see a problem with lots more data. When you click on the Blue Header Arrow does it hide the info?

The Grasshopper name is on its way to become genericised. In the future we'll say, "I used to work on the original grasshopper" or even "I used to work on a really old grasshopper called XPresso, before there were grasshoppers."

I totally agree, and actually see a maybe overlooked advantage. Grasshopper users are becoming more valuable as their skill sets can now be extended to operate in revit, blender... or sketchup

@Vicente,

I've never used Cinema 4D. Interesting to see that their XPresso first appeared in 2002 with the release of Version 8 http://www.digitalpostproduction.com/2003/09_sep/tutorials/ko-8-xpr...

We thought about naming "toster", because of "blender" name ))

You all talking about name, something else, it doesn't metter. Instead, main feature is opensource.

Nobody will take it from you.

To patent the principle of visual programming is too late, as you know.

For those who talk about transparant nodes - it is blender at all.

We only realized good known features on blender base. And Sverchok at beginning of existance.

To patent the principle of visual programming is too late, as you know.

The way they are handing out patents now a days you never know.

Naming has to do with trademark, not with patents. In any case, copying aspects of Grasshopper will probably fall under copyright violation.

Many detractors of intellectual property are not necessarily against trademark since violating it can be seen as a form of fraud. For example, in the fashion industry you can duplicate a design  as long as the article doesn't have the name or label of the original designer.

Btw, this is not to criticize anything you are doing, personally I don't think current IP laws are conductive to innovation and generating net wealth. They seem more akin to a government granted monopoly rather than protection of actual property. So keep up the good work.

For those who talk about transparent nodes - it is blender at all.

I've not used Blender. Which bit is blender and which bit is Sverchok?

Is Sverchok to Blender in this case like Kangaroo to Grasshopper i.e a Set of Nodes for specific tasks?

@Danny Boyes,

Blender is 3D Sw as 3dsmax, and has node system for making materials and for making piscure post-processing, some time ago appeared posibility to use nodes just as you want with blender API and python/C libreries.

So, ours part is to make little programms/nodes that makes some math analisys and operate with universal data, as vectors, polygons (list of vertex' indexes) and matrixes (scale, location, rotation).

And we made OpenGL representation using OpenGL/blender API and we made text viewer using inner text editor of blender.

So, sverchok is something different than GH

It looks nice :) For me if it's open source for me is pretty fair what you are doing, just change the name and jump over the trademark stupid problem ;) 

Anyway...I woldn't post this here...is nothing about GH neither RH or related to Mcneel product ;)

I respect GH and RH. And want to tell again, in context of blender we couldn't achive same wide toolshelf as GH has, and have different approach sometimes, so sverchok can be used parallelly with GH, do not see anything brutal to post it here from this point. We are not opponents for GH.

Let it lay here.
