    Default Re: Performance issues with many Samples and closestPoint()

    I wrote a funktion like closestPoint() now, but let it search from 'x-position - 250000 samples' to 'x-position + 250000 samples', instead the whole curve. This makes the cursor also snap to edges at huge amount of samples, when the cursor comes close to the curve.
    I am pretty happy with this now. Thanks Uwe for all the help!
