algorithmic modeling for Rhino

(Edit. David sez: Please append your (well explained) ideas/suggestions/wishes. I don't care much for what you want, I care why you want it.)

Perhaps this topic has been covered recently, but I don't see any active threads.  We're looking for a plugin project and I'd like to get some feedback from the power users before choosing something.


What is missing from grasshopper?  

What would you like to connect to that you can't already connect to?

What kind of bottlenecks do you run into?

What secret wish do you have for Grasshopper that doesn't even seem possible?

What project have you been meaning to undertake but haven't had/won't have the time?

Just trying to brainstorm a few ideas here.  There are so many great and useful plugins out there, it's hard to discover the gaps anymore.   

Looking forward to your thoughts!

I can't switch it without hiding the current component and introducing a new one. I think it will have to wait until GH2...

hi, I am an architect, designer and artist. I have suggestion for the next GH development. from designers point of view, I think GH should have a special Tab to utilize WACOM Tablet, I have created a post that explain about this issue,

as designers, we are more convenient working with primitive tools like Pen, stencils, knifes etc to draw or sculpt an object, whether it is an architectural masterpiece or a simple furniture, if you can feel the object on your hand, the design will always come up better.. and WACOM tablet is so far one of the best tool for 3d artist to work with, however Rhino+GH doesnt seem to have any of those function.

Imagine if you can incorporate WACOM tablet into GH, u can send complex input (pen pressure, tilting angle) in a matter of second and then GH component will process that input and  view the changes in real time.

-modifying complex control points would be just as easy as sculpting a clay (imagine Zbrush but added precision and Parametric control)

-multi slider can be adjusted all at a time, complex wacom input is much more powerful than standard mouse.

-wide range of workflow from NURBS and Parametric algoritm to variable and freeform deformation data with WACOM

Imagine the possibilities, WACOM tablet now has become an industry stardard for digital artist, so GH needs to grab that opportunity (u can attract more user too by doing this. more user = more money LOL)

Peace :)))))

Grasshopper is powerful , we take it for granted and there are always expectations such thing is loading grasshopper... loading multiple user objects and plugins takes time, I am not sure if anything can be done regarding this issue.  

I can probably speed up loading significantly by doing it lazily. The first time a plugin is loaded a "proxy" is made which contains only the names and icons of the components. Subsequent starts will only load the proxy, and either load the real plugin in the background or only once it's needed the first time.

I haven't actually written this bit yet in GH2 so I'm not sure how much faster it can get, but I'm hopeful it will speed up startup a lot.

Thank u ..David .

Here are my wishes for GH 2 in Rhino V6 :

-Full integration of Kangaroo in GH

-Allow the use of a 3D mouse to pan/zoom in the GH Canvas

-Detailed help for each component with simple examples of how input/output, similar to what is found in the Rhinoscript help.

-Full featured remote so that definitions can be used by non-programmers

-Single type of vector output, but with parametric control over all the characteristics (color, arrow style and shape, line thickness, "solid" option etc...) 

I guess that's it


-Allow the use of a 3D mouse to pan/zoom in the GH Canvas

Actually what would be really cool....

Having the possibility to use a separate space navigator just for Grasshopper. That would mean also a separate mouse for Grasshopper 

Another very small request:

Please let [Merge] start with D0 instead of D1 due to continuity. 


Add on: Also it would make sense to have [Entwine] by default in the simplified version to keep paths easy and readable.

I'm wondering if thought should be given to make GH2 a self contained program.

1. Being able to open multiple windows, of the same project at the same time would provide on the fly component cutting and pasting, with a Freeze wire option, and its own GH2 viewer.
2. Provide Export/Baking to various file formats.
3. Rendering, with GPU support, optional.

My 2 cents :)

Grasshopper relies heavily on the Rhino geometry kernel. Several really smart people have been working on that code for over a decade, so redoing that is not an option.

It's also not entirely clear what McNeel & Associates stands to gain from such an effort. At the moment Grasshopper is free but requires Rhino (which is not free). If Grasshopper is available separately, we'd have to charge for it to make it cost-effective. But is it a viable product? How much would we charge? Would be actually bring in more than the additional Rhino sales we get at the moment? Nobody knows, and it's risky to abandon the current solution, which works fairly well.

I understand the dilemma totally. Its not easy to abandon something in which one has invested so much time. 10 years ago I finally decided to cut my 20 year AutoCad Umbilical Cord. This was not an easy decision. It took me a long long time, I finally came to the conclusion that AutoCad users, thru AutoCad User Groups had become nothing more then Beta Testers while paying full software price. Then one day you discover Sketchup, and you are able to bang out quick 3d proposal, and now even working drawings, with blinding speed. Rhino is in serious need to simplify, look at capability of the Moi interface.
