Trying to animate an extrusion in 3D using curves generated by an equation over time.
I can create a 3D spiral pattern using python and animation nodes but how can I extrude the curves so they vary over time and in 3D?
The Python code I'm using is:
import math x1 = a*math.sqrt(t)*math.cos(t) y1 = a*math.sqrt(t)*math.sin(t) z1 = -t x2 = -a*math.sqrt(t)*math.cos(t) y2 = -a*math.sqrt(t)*math.sin(t) z2 = -t position1 = Vector((x1,y1,z1)) position2 = Vector((x2,y2,z2))
See attached animation of what I have:
The image I'm trying to recreate is the Lily Impeller and how it's created/growth pattern takes shape over time.
Here's a video of what I'm trying to model/animate the growth pattern of. https://youtu.be/by0JhirtO-0?t=224
I was thinking that the curves need to be extruded in the -Z direction at a 60 angle but I couldn't come up with a way of how to do this.
I'm open to other ideas or suggestions on how to do this.
