Hy i write a plugin where i create a Spline connecting circles of different size as well as including their part in the new Spline too.
Till yet i have all needed Points for my Spline but when it comes to the Tangents of those Points the Bezier-Curve is still giving me a headache.
From normal circles i found that all 4 (90° to each other) Points have the Tangentlength of 0.415*Radius .. but if you cut the circle somewhere those values change ...
Can someone tell me how to calculate the lenght please ... the formula would be great ... perhaps there is already a way to get that ...
My idea yet is that it might be related to the arc of the circle but how to go on from there?
Thanks for any suggestions,
