clamp a wiggle expression

[andrzejgoulding]

How do I go about clamping a wiggle expression?

I am using the mosaic effect with a wiggle expression on it. The only thing is that I never want the number to become 1, only 2 or higher as with 1 the mosaic effect make vertical lines that I don't want.

Cheers

You could use the linearize function to limit the numbers. You must remember that if you set wiggle to 3, 20 that the wiggle will happen 3 times per second and the value will be between -20 and 20. Also, since you're working with Mosaic you would probably want to round the number of columns. The expression would look like this:

t = wiggle(3, 20);

n = linear(t, -20, 20, 2, 10);

Math.round(n);

This would wiggle the horizontal or vertical block number between 2 and 10 three times a second.

Thank you for your reply, this is great.

Thank You.

Rick's linear is a good approach.

If you really just want to clamp you do it like this

var wiggleResult = wiggle(/*your parameters here */);
var clampedWiggleResult = Math.max(2,wiggleResult);
clampedWiggleResult
