Spiral

[joeleo]

Does anyone know of a good way to create a spiral in Wildfire 2?

Hi Joeleo


planar or 3d? anyway use an equation.. or if 3d Variable section sweep with trajpar and intersect with a cone


try a search..

Here is an equation for spiral curve. go to curve>>from equation>> and select a csys, use cartesian and write this equation.


x = ((d/ 2 + P * r * t) * cos ((r* t) * 360))


y = ((d / 2 + p * r * t) * sin ((r * t) * 360))


z = 0


where, d ----> Inner dia


p ----> pitch


r----> No. of revolutions


If z=t*360, a curve look like a spring will come.
