Hello there!
So I’m here trying to get a double helix perfect circle.
I have the helix, make it double, not a problem, but then I ve tried using twist node without succes, I bent it in all possible ways and it never falls perfect on other tip of this helix.
Any clues how I can achieve this? THX
Depending on what you’re doing, you might want to check out the Houdini cookbook, with a bit of effort you can convert all the equations to TouchDesigner ones:
sidefx.com/docs/houdini/ref/ … kbook.html
Would give you more control over the design
Good idea! I’ll try that, great houdini and TD and slightly compatible.
Well on my side I found its actually called a ‘torus knot’ in shader toys (no perfect helix but will do). I I managed to isolate that one.
then I found this video

now that would be ideal! lol
I’m rubbish in math but we will persever.
last question;
got this helix which is basically a line connected to a pointsop
with these formulas; sin($TY*par(‘…/Frequency’)100) in x
$TY in y
cos($TYpar(‘…/Frequency’)*100) in z
how can I taper both sides of that helix , the idea is to make a path for a ball of particles so it can spin around a glob in shape of sphere instaed of shape of a tube. If you see what I mean. How can I set a limit to tha sin and cos pretty much (with a +50 at the end or something).
Twist node wont do it.
I know its a bit far fetched and badly explained.
