Tip to speed up your plug-in if you have to walk along a long Path

[trandoductin]

it's been so long since I visited this forum.
Just wanted to share this here if anyone has slow code due to having to walk along a path.
That's all for now, cheers.

Never had the problem. How many calls are you doing in a single path?

Too many,
to get all the points based on user option to specify speed to walk along the path while applying 3D wobble.

If you apply a wobble, you don't need much accuracy. I would look into pdb.gimp_vectors_stroke_interpolate(path ,stroke,precision). This gives you [length / (2 *precision)] points that approximate the stroke with a polygon (for  instance, a 800px stroke with precision 5 yields about 80 points, spaced 10px **on average**). So you get a very fast (even if less accurate) point_at_dist by getting the point in the array (or interpolating between two points in the array).

Thanks for the details...I'll look into it when I feel up to it..
right now I am too excited about something else
