SgtSpamBoy Posted May 28, 2010 Share Posted May 28, 2010 Hi, I'm trying to develop a good method to make a tapered 3D spiral that can be easily modified. 1) Ideally, I would like it to taper into a consistent spiral, like a spring with an unraveling end. I've created the tapering part using expressions on a point SOP (any other method is welcome, as long as it can be easily customized), but I'm unsure how to get it to go into a consistent spiral. If you notice, it tapers in both amp and freq. 2) I would also like to taper the point density so that the curve would have fewer points where it is more straight, and relatively more points where it is coiled (see image). I've tried resampling, but the closest I've gotten is combining "even X segments" and "even Y segments" with two resamples - the result is close, but kind of ugly. Thanks for any help here. Again, any method of creating this is welcome (I also like using creep/sweep to make spirals), but I've attached my hip file as well. 3d_spiral_01.hip Quote Link to comment Share on other sites More sharing options...
mightcouldb1 Posted May 29, 2010 Share Posted May 29, 2010 Look at the refine SOP with "unrefine" to get less points in areas with less curvature based on the tolerance. Quote Link to comment Share on other sites More sharing options...

That works nicely. I played with that before, but didn't notice the "unrefine" tab until now. This solves issue #2. Quote Link to comment Share on other sites More sharing options...
