MAthmatical deformations of a line.

[eadint]

I dont even know where to start with this one so any tips would be greatly appreciated. what i want to do is create a line or a tube. and perform a mathmatical deformation to it. essentialy i want to deforme the tube or line to a sine wave over time is this possible and what plugin would i want to use.

Make your object in modeler then export to layout. Add the Mathmorph deformation plugin. Enter your equation...

There's a mathmatical displacement function in modeler too probably...

I applied a sin(f) to the y point in the formula and it just made the whole thing go up and down. any other sugestions.

Of course it did. It's taking each point's position and adding sin(f) to that point's position. Thus as f changes over time, the object as a whole will go up and down.

If you want a sin wave rippling through the object, you'll need to incorporate the x/z variable into your equation.

.5*(sin(x*4+f/10)*sin(z*4+f/10))

gives a nice ripple across a 1m mesh which has been judiciously subdivided.
