Two other brilliant posts on Bézier curves (and other 2d&#x2F;3d curve types):<p>- Curves and Surfaces by Bartosz Ciechanowski: <a href="https:&#x2F;&#x2F;ciechanow.ski&#x2F;curves-and-surfaces&#x2F;" rel="nofollow">https:&#x2F;&#x2F;ciechanow.ski&#x2F;curves-and-surfaces&#x2F;</a> (His whole site is a treasure trove of incredible explanations!)<p>- Primer on Bézier Curves: <a href="https:&#x2F;&#x2F;pomax.github.io&#x2F;bezierinfo&#x2F;" rel="nofollow">https:&#x2F;&#x2F;pomax.github.io&#x2F;bezierinfo&#x2F;</a>

this video: <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=aVwxzDHniEw" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=aVwxzDHniEw</a> is quite instructive as well...

Is there a way to perform direct Bézier-path intersection, union and difference operations?<p>I lately tried to find some options for a hobby project. The only way I could find was to first break the path into a lot of line segments, then do the logical operations between paths and finally convert them back by trying to fit Bézier curves into the resulting line segments.<p>Conversions back and forth seem less than optimal and can lead to artefacts. There must be a better way.

This Bézier primer is really interesting too, one of the best resources if you need to implement anything related to Bézier curves. <a href="https:&#x2F;&#x2F;pomax.github.io&#x2F;bezierinfo&#x2F;" rel="nofollow">https:&#x2F;&#x2F;pomax.github.io&#x2F;bezierinfo&#x2F;</a>

Stumbled into this world trying to make pretty Sankey diagrams. Offsetting beziers is much more complex than I anticipated.

what is most interesting to me about bezier curves is how they introduce a &#x27;time&#x27; parameter.<p>referring to how they switch from two coordiates (function arguments) into just the one &#x27;time&#x27; argument.<p>this is most clear in Bartosz Cieachanowski explanation.<p>then the whole topic gets really going when they add multiple lines all parametrized with the one &#x27;time&#x27; argument.
