Node Graph Interface

TC
Hi,
I made a Node Graph Interface for OpenSCAD as a hobby project (written in Java).  I have it working the way I imagined and thought I'd throw it out into the wild.  The concept was to make Nodes that are elemental parts of the language.  There are Nodes for atomic parts like numbers and variables and Nodes for typical statements like sphere, translate, union, etc...  It doesn't cover the complete language, but there is a "hack" for the rest.  The README.md at the project page should get you started. 

Project Source:

You can pull the jar file from here:

I started this project after reading a Hackaday article about choosing CAD software.  OpenSCAD got mentions in the comments, but I think people are intimidated by the typing part...  Like others, I have always wanted CAD on Linux and have looked into OpenSCAD (I'm only a windows person because I'm a Rhino user & ex AutoDesk user).  So, the thought struck me: what would a Node Graph interface like Rhino's Grasshopper or Maya's Shader Network look like in OpenSCAD?  This was my musing on that thought...

Cheers,
Tom

This is very cool  Anything that can appeal to more persons is a good thing.

But for me, already being comfortable with the typing aspect, the node interface looks intimidating!  :-)

Thanks
Kevin

Re: Node Graph Interface

William Adams-2
How does this compare to:


If one puts together a file and then opens it in OpenSCAD would the Customizer work as expected? (that's the major failing in graphscad for me at the moment)

Could this be adopted to other languages?

As a naïve user not accustomed to working with Java source, how would one start with this?

I've downloaded it and found \NodeGraphInterface-master\build.xml --- a brief search indicates this is usually an ant build script? Is that the case here?

Re: Node Graph Interface

Also, did you consider implementing this using an existing tool?

Blockly seems a likely option, or Drakon?

Thanks & LOL, Yes that is a bit of a spaghetti example I have up. Typing will always be more powerfull/expressive in the end - I tend to agree with what others have said regarding node graphs in that they have their limitations (especially when faced with complexity).

I saw that project after I got started on my own and felt we took different enough approaches that I wouldn't be stepping on their toes by releasing this one...
I have no idea about the Customizer - I've heard of it, but haven't looked at it.  I tried not to clutter up the output file - you should be able to mimic what you would normally  type.  I'm storing the node information in it's own Java Serialized file - not in  the SCAD output file.

The project was done in NetBeans IDE 8.2.  You could port it to a different language in theory (it's just a string concatenator).

Re: Node Graph Interface

William Adams-2
What I meant by language was taking this software and having it support something else in addition to OpenSCAD, say METAPOST.

How would one begin using it? Do you have to download NetBeans? Is there some command line command to either compile things or get them started?

Re: Node Graph Interface

William Adams-2
Okay, managed to puzzle things out. Quick start:

 - install Java
 - double-click on the .jar file: NodeGraphInterface-master\dist\NodeGraphInterface.jar
 - right-click to create nodes (e.g., Node | Geometry | Cube)
 - output is handled by the object Node | Output | SCADOutput --- right-click on the "f" to get a file dialog which will allow you to send the output to a .scad file which OpenSCAD will open

One thing which seems a bit odd to me is that everything collapses to the most concise possible expression, and no structure is preserved, so the graph:

Capture.PNG

is presented as: 

    cube([50, 100, 25], center = false );

It would be much more useful for my purposes if the parameter values and names were preserved and presented at the top of the file so that they would work in the Customizer in OpenSCAD. c.f., https://www.blockscad3d.com/

I can definitely see myself using it to work up code to include in modules in other projects.

Re: Node Graph Interface

TC
Oh, I think all you want to do is explicitly declare variables - just a few extra nodes... :)

The attached image produces this:
Width = 7;
Length = 5;
Height = 3;
cube([Width, Length, Height], center = true );


HTH,
Tom

It would be much more useful for my purposes if the parameter values and names were preserved and presented at the top of the file so that they would work in the Customizer in OpenSCAD. c.f., https://www.blockscad3d.com/

I can definitely see myself using it to work up code to include in modules in other projects.

Re: Node Graph Interface

William Adams-2
Thank you!

I see how that works, and I think I can grasp the logic of it, but it's not something I ever would've worked up from playing with the interface --- is there way to combine the Variable/Assignment/MergeBlock into a single node (which ideally also shows the value as I had in my previous example? I see that you can add a 4th Node for a Number to expose that value, but that gets even more spread out.

Re: Node Graph Interface

TC
I think this is as good as it gets for what you are trying to do. I'm not sure what you are describing when you want to combine  the nodes (you are still going to need to tie into a MergeBlock if you need generate multiple lines of code).  They are all separate for a reason and used for different contexts, i.e.: Assignment node is also used for Function and Module definitions when you want to specify an input with a default value (hence the semi-colon toggle). I don't have any immediate plans to address the displaying of static values in all nodes - it would take some tweaking of things (I've looked into it before).

Re: Node Graph Interface

Troberg
In reply to this post by TC
While I don't think I'd ever use this in my typical programming, I can still
see two great uses:

* Teaching tool. I would never be able to get, say, my wife to start writing
code, but this is something I could get her started on. Once the graphical
method gets restrictive, the transition is trivial, because the
understanding is already there, it just needs to be mapped to text instead.

* Debugging tool. If it could be made so that it can import a script as
well, it makes it very much more visible where I've messed up. Example: A
missed closing bracket can be hard to spot, but in the graph, it would be
obvious.

Keep going, it's a great project!

Even if there was some mechanism to group things together that would help a lot.

Currently I'm using Blockly/blockscad3d and it seems to be working well, but I'll certainly circle around to nodegraphinterface and graphscad when I run into limitations in it.
