Re: Decaying squiggle

[Andrew Bernard]

Hi Jacques,

Indeed yes. The complexity comes in when you realise that once you have the function and it’s derivative - that is the easy part - you need to compute a set of bezier spline segments that approximate the function in order to use them in Postscript path creation. This is decidedly Not Simple (TM).

The code that was posted here is remarkable and very nicely done in this respect.

Thanks for your input.

Andrew

They show how to draw a decaying wave with:

y_damped = sin(2*pi*330*t).*exp(-t/tau);

 

I guess this could be done in Scheme, couldn’t it?
