Modeling curve scuplture
-
How would you model something like this accurately?
-
here's my Super rough first try... i went around the thing too many times... 2nd try should be easier and i'll try smoothing out the kinks..
-
Id try and do it by drawing and connecting arcs, you could draw the arcs on a plane so you could get the angles and stuff a bit more accurate, otherm than that im not sure. Quite a challenge.
p.s. use the arcs and stuff for a follow me path.
-
I was not even going to attempt that complicated shape, I did however do a little spiral and render it as glass.
-
solo, spill the beans already, are you beta testing v2.0?

The shape is a mathematical curve called a trefoil. I created one using using knotplot and shipped it into Sketchup.
In the render I forgot to smooth the skippy so it went a bit jazzy!

Nice one bob, far cleaner than anythign that could easily be produced in SU! cheers for sharing it.
edit: i was going to try and do a render of this in podium, but podium is struggling slightly (a lot!) with it.

It looks really good, but it lacks caustics...
-
Thanks Bob, nice find.
With caustics -
ha.. man, i was just starting to get my head around what's actually going on with this shape and was about to start trying out the proper curves... then i open up this thread... i'm throwing in the towel after seeing knotplot..
check out this project..

a non transparent version..

Solo,
Is that Vue you are rendering with?By the way, I wouldn't have a clue how to model a doodle like that in sketchup..
-
I am great fan of mathematical shapes. Nice model, did made a subdivision in KT. Take a look on k3dsurf, nice program for creation of mathematical models.
-
This is an amazing response, Thanks Bob! I'll try my rendering in K when I get a break in action and post my attempt. There is so much useful knowledge generated here
-
My attempt rendered with KerkyT.

tried one with cheetah.. just using the trial version for now (everything works normal and it doesn't expire - you just can't save anything.. this is a screen shot)..
