Hello Brian,

<<<Yes, hoopsnake. I wonder if nodeeditor has "feedback" detection code?>>>

I think that's a general problem - no special code is needed. The nodeeditor needs startpoints/nodes to start the calculation from an independent node. In a closed loop we need a intial startpoint and initial value(chicken-egg-problem). At a minimum we need an independent node that defines the step in to the loop and gives the initial value. I think it's possible to solve.

Have a nice day
Karsten

Hello Ralf,

thanks for sharing. I have to study your nodes now.

Have a nice day

Hi All,
while searching for Hoopsnake came across these video's

Hi Barry,and Friends
in Grasshopper besides " Hoopsnake ", there is also
another Plug called "Anemone ", which also works maybe better,
and there is also the possibility of using " Kangaroo " a physics engine to move
rigid bodies, in various ways ,
but all these tools use a Button , True / False, and a connection Timer, to activate
or deactivate the action .......
and , the input data can all be adjusted by a Slider or direct links to the data in the Canvas-
I have not knowledge of Java Script, but I think it is not very easy
create a Collide / Repulsive tool
in any case, your attempts are very appreciable
do not give up......

Hi all,
is it possible to create a nod from existing node's that stores a count and would not be cleared till it is reset or create a new node that does that.
Cheers
Barry

Storing a value seems to be a problem...
I didnt find a way to do it with existing nodes and i created a extension with a memory node.




if you set it to 0 it gives the IN values to the OUT if you set it to 1 it stores the last value and gives this to out...

BUT: if you add a second one it doesnt work anymore...
Somehow both react like one.

Perhaps Karsten finds a solution...

2 fully interwoven screens.

Wanderful!

All these stuff are very useful for renderings of 3D concepts and/or geometric art to include into 2D works (after some post process elaboration)

Thanks a lot.

Intricated!

Thanks James.

Wanderful as usual!!

Math made art :)

Hello James,

great result. Thanks for sharing!

A nice day to all

New Camera nod..

Now setCameraAndTarget is working again in V4 i desided to play with the camera nod ... the original is not working like expected and i changed it a little.

Now its camera2 and it can circle around objects, render picts and even make a video out of them...

For Mac:
to enable video you need ffmpeg in /usr/local/bin/ffmpeg put this path in the encoder field
in the FilePath field write something like /users/ralfnaumann/Documents/CAD/camera/

You will find the camera2 nod in attached r2d3.js -> put this to the extension folder (there are also some other nods inside - but not all are working perfect...)

As example to use the camera2 you can open camera1.nod

Amazing node Ralf!!

Thanks a lot!!!

Hello Ralf,

thanks for playing and improving the node. I think you were the first that was really interested in. I have never finished the node really - zu wenig Zeit, zu viele Aspekte!

Bis dann
Karsten

Question about genious creators of nodes!

Have you a place on the Net where we can find your true gems ?

(French version of camera is pretty soon ready :)

Done! :)



where I must put the .js file (in extensions ? )

because now the only thing I have is the centering and blockage of the object in the 3 D view... :D
using cursors don't get nothing special!
What I miss ?

a pedagogic gif is need! :)
Tested in the V4 11 november...

There is just one more gem... www.esherpa.ch ... makes my life as a tandem pilot much more easier... with the help of MoI!
Winter time is not very busy for me and instead of SuDoKu i play with nodes...

Merci pour la traduction

You're right Ralf!

@You : "...instead of SuDoKu i play with nodes..."

Moi is really the "funniest 3D Cad" ever !!! A sort of video game into the CAD world ;)

And, above all, although it is so funny it's also awfully powerful for serious things!!

<<<where I must put the .js file (in extensions ? )

Yes, into the extensions.
than open the camera1.nod adjust the camera x/y/z and the target x/y/z
Hit run and the camera circles around the target (if speed>0 and its not on Stop)


EDIT: IMPORTANT: You have to use the last V4 the earlier Nov version has a bug in "setCameraAnd Target"
