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...

Thanks Pilou, Al & Marco,

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

UPDATED:with 2D/3D switch

Have a great weekend

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!

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,
of a fascinating and particular surface in my opinion, Dupin Cyclide Ring -
how many interested people find the file at this link:

Good depth to everyone
Have a nice day to all

Hi Al et al,

That's very cool. I was impressed by door mechanism video on dezeen: https://www.dezeen.com/2014/02/11/door-reinvented-with-folding-mechanism-by-klemens-torggler/
but even better to see it animated in NE. Great work.


Maybe you can help me with a problem.
I have been trying to get my head around voronoi tessellation.
(I recognise that this may be a redundant exercise if/when Max converts his script to a node)

I have started with a mesh of triangles*, applied planar, extracted edges,
getStframe, generate 3ptCircle and find centers with BoundingBox node.

Now it is a matter of drawing lines between centers.
This involves incrementally taking pointDist for each point with the rest
and drawing the shortest (extract Min - compare - split),
then repeating for new minimum distance (2nd shortest) & again for 3rd shortest.

I have not included the nod file because frankly it is not even close to working as I desire.
Perhaps this is beyond NE as is, but I thought you or someone else might have an idea of how to proceed.

James

*Ideally, what I want to do is input a field of points and apply a Delaunay triangulation as my starting point;
though if that was possible, the same code could probably achieve voronoi meshing as well.
