NEW NODE: Flip

Hi All,

I have found when flowing multiple patterns to polylofted surfaces,
that at times the different tile elements can have opposing surface normals.
Although this often can be reworked to avoid this problem, I have nevertheless
created a new, very simple, node that calls 'flip' factory.

To demonstrate its use, see also attached flip.nod and image:

A planar surface is copied & Moved, then Flipped.
The 2 resulting planes are offset by same distance
however in opposing directions due to reversed normals.


Also when applied to a curve it changes its direction
(i.e. flipping start pt and end point)

To use this node, replace construct2.js in extensions folder

P.S. Ideally, I would like to see this functionality incorporated into a tripartite node
that also replaced Marco's "ArrayFlipper"(flipping a point array) as well as
a Numbers option for flipping a numArray (reversing list order).

I lack the programming skill to do this, but if anyone is interested, it would be
a worthwhile exercise IMHO.


UPDATED:
Added dovetail.nod to demonstrate flipping curve

Hi All,

Here's a simple example of the use of "flip" node.

By flipping alternate facets surface normals, flowed geometry will flip according.

NB: construct2.js needs to be replaced at
C:\Users\<user name>\AppData\Roaming\Moi\nodeeditor\nodes\extensions\construct2.js

& interface.js at
C:\Users\<user name>\AppData\Roaming\Moi\nodeeditor\nodes\interface.js

Hi All,

Here's something I'm working on at the moment.
It is like a fisheye lens filter for spheroidal distorting of geometry.

Have a great weekend
James




UPDATED:
Also emulating Pinch filter for geometry.


UPDATED: FishEye.nod file attached.
Nodes in green can be adjusted, but be warned that highest magnification may cause long periods of lockup (spinning wheel) with focal point at the edges; best to stay towards the middle. With mid range magnification, there are no such issues. LENS TYPE switches from FishEye to pinch modes.

UPDATED: Also added switch for 2D or 3D bulging.

Or useful for car's tires design! ;)

Very cool
Can you post the nod file....?
Have a nice day,James...

Wonderful!!

Thanks Pilou, Al & Marco,

I have now posted FishEye.nod to my previous post:

UPDATED:with 2D/3D switch

Have a great weekend
James

James you're becoming a "true master" of this kind of "mathematical art"!

Congrats!

In this period of my life honestly this is not a CG topic that's so much interesting to me, but I want to tell you that your contribution to this particular area of Moi, the NodeEditor, is really amazing!
I think it's (almost) on the same level of what Max did with all his amazing scripts.

Thanks for your passion!

I can sign Marco's words!

Respect!

Mik

Hi Marco,

I have been buoyed by your kind words, although I don't
believe I am deserving of comparison with Max on any level.
Nevertheless, I'm greatly appreciative of your encouragement.

Thank you (& Mik)
James

You're welcome James! I think that you deserve due recognition :)

Ciao!

Hello Friends
An exploration, I think quite interesting,
