Hello,

would someone post Al's last nodefile - Mediafire isn't working for me at the Moment.

Thanks in advance!

Hi Karsten.

Here is the file : http://take.ms/kAx7x

It is a modified version of the node based on your indications found in "Deviations.xls" that you posted of some days ago.

It works for me.

Ciao!

Hi All,
I don't know if I'm reinventing the wheel (it can probably be done with the existing nodes)
but I have managed to coded a simple Key Frames node to use for animation.
It as the following features.
1) Inputs: Time, action start and action end.
2) Output: Count and action length.
I'm new to javascript so if someone cares to have a look over it and tell where it can be improved
that would be great.
Many Thanks
Barry

Hello Friends
this my fifth Macro
- Bezier Curves by an open or closed polyline-
it is a great flexibility tool, and I also hope for usefulness
in the drawing

Input:
Open or closed polyline
Output:
Bezier Curve

the file is at this link:

Have a nice day to all
... (for my friend Marco, thank you for your appreciation )

Hello Barry,

Looks great. For the Keyframes-Node the mode:[ "Long",...] isn't used and not necessary. So you can remove that. It is only useful with multiprocessing.
If you want to make film sequences you can also use the camera node. It makes single Pictures from each step. After that you can join them together with ffmpeg or mencoder(command line).

Have a nice day
Karsten

Hi Karsten,
thanks will try the camera as you suggested.
Barry

---

p.s.: You can also use ImageJ to convert the pngs to an avi. For that use Import->Image Sequence , Then save as avi:-) For a not moving camera you have to Trigger the node with a constant value from the quartz node eg. a math node that gives allways a constant. Choose a path and Directory e.g D:\test\ for Windows systems.

---

Hi Karsten,
can you explain or post a simple nod file showing how to use the camera.
Also is it possible to do a fly thro with it.
Thanks
Barry

---

Hello Barry,

test the attached node file. Switch to 3D-Viewport and press run. Now stop. Double click the camera node. Insert a valid file path. And switch save to On. Press Run. Now every position of the camera will make a single screen shot. Starting with the start index up to Frames number.

Have a nice day
Karsten

Hi Karsten,
thanks for the camera nod file looks like I will have plenty of options for recording
animations with added camera movements to give walk thro and around.
So again many thanks for your help much appreciated.

I have a problem with the ObjToArray nod. It seems not to work (for me)...
With my nod i like to select a straight line and draw a circle around the start and th end point of this line...
But ObjToArray seems not to give any array of points.
What is wrong?

Hello R2D3,

The objToArray node converts point objects to a pointarray. So a better name would be Pt-ObjectsToPointArray but that's to long;-) I think that what you looking for is pathArray or mPathArray - to find under Points2. The node takes input curves evaluates an orientated frame at the start point and distributes orientated frames along the curve. The Div value defines the amount of frames/Points along the curve. The orientation option controls the orientation along the curve. The order option is only important if you have multiple curves: Along gives you an array with all points from the first curve followed by the points of second and so on. Across gives you an array with the first point of the first curve followed by the first point of the second curve and so on. The point array has an internal organization to cluster the points. Following nodes e.g. Curve can break this clusters to independent curves. Have a look to the attached node file. Don't forget to reselect your curve.

Have a nice day
Karsten

p.s.:
Circle can take also multiple centers - so there is a shorter way:

Ahaaa :-)

That makes it clear now - and it works!
I like the idea of the nodebundle project very much - playing around with them is fun (even without docs...)

Thanks a lot Karsten

Hello Ralf,

most of the nodes and the functionality of the extension are build by a user request or a missing functionality of the core. Max can't write everything by itself with respect to his time and work on the core. The different aspects of use for such an application is a wide field. So it's not only a tool for generative geometry creation, its also a generative process to get the tool. The documentation was not in the focus. I tried to start a wiki, but I was the only one who wrote something. Nevertheless there is also an outdated Excel sheet where you can look for some functionality:
http://moi3d.com/forum/index.php?webtag=MOI&msg=7777.200
Maybe the menu position had changed, but node names and functionality should still work.

Have a nice day

Hi,
I am playing with James surf to Pnt.nod and I am getting the result shown in photo.
The panelling is covering all the surface except for last line.
Is it possible to cover this ?
Cheers
Barry

Hello Friends

my sixth Macro
Rectangular grid;

Rectangular center
Rectangular points

For those interested , file at this link:

Have a nice evening to all

Hi Barry
maybe it depends on the surface
one should know if it is a single or Trimmed Surface ,
I think in the second case there may be problems
you should do some tests ..
Anyway my and only an impression, but I could check it out
that the Isocurve command, on which the James macro is based, sometimes gives the
problems, dependent on the Extraction Surface

UPDATED: "retop.nod" & image

Hi Barry,

Please find attached nod file with new macro for U&V isocurves
and points at their intersection.

Image below shows surface faceted & point mesh to extents.





Also Karsten mentioned that he had developed a "network" node that
combined with "retop" macro U&V outputs will retopologized input surface.
I will incorporate "network" node within the macro, once it is delivered.

James
