ICE - Sine Function Deform Object X-Axis - Help?!

[gl2748]

Hello. I am new to ICE and am having some trouble.

Objective: To make the blade of the sword deform along a sine wave, Ideally 1.5 wavelengths along the entire blade length. A similar objective might be to make a fish make a swimming motion with its body.


Problem: I am applying the ICE Tree as pictured. I cannot figure out why it is 'Crushing' The X values. The blade volume essentially collapses.


Request: Ideally a screenshot of the correct set up in an ICE tree. I have personally been working off:http://xsisupport.com/2009/11/17/sine-waves-in-ice/ And think my problems might stem from the geometry there being a grid...

THANKS!

I think you're off to a good start already,

you probably could go completely without the distance from center attribute

you'll want to add an offset to x depending on height y, so let y and z pass directly through like you did, but pass y also into your leftmost multiply node, adding it to the original x and then pluggin it into your scalars to vector's x

You'll need to add this sine deformation to point position, I think that's all. Let's say, convert output of sinus to 3d vector, leaving Y and Z components empty (or zero, exactly) - then just add this to self.pointposition.

Hi Mathaeus and RRay! Thanks for the speedy reply. My first ICE Compound. Thanks! Hope it's useful!

Congrats!

You can do a few things with this that might be interesting to you...

- You can remove the null entirely and just use point position. To control movement/position of the wave, add a phase shift value (just an 'add' node) prior to your frequency factor...



- You can also use a rescale node to make the effect fall off based on the y value. Try taking the "Y" and rescaling it from 1 to 0, and multiplying that with your amplitude or strength value and play with the rescale values. This way you can blend the effect to make the part where the sword nears the hilt stay as it was originally modeled.

- You can use a "case" node in your final compound to let the user choose between deforming on the x or z axis, or both, etc.

Always great to watch someone make their first tool, congrats and well done! Deformers are fun.
