Description
I wanted to draw this illustration using graphite, but ended up using desmos and screenshotting it, because they support parametric equations. It will be nice to have such a node.
I think that in this node we should be able to specify density of the geometry (amount of points), because different equations require different density, and it can affect performance.
I think there also should be density multiplier for the export rendering (if there is such a regime). So that at the editing stage we may see segmented geometry, and for the final render it will be smooth.
Also, unsolved problem: how to make this node accept any amount of variables (so that you can tweak behavior of your equation, like l in my example). This is also the problem for the Math node. Without this, this node will be not as useful is it might be. (#2462, and see also #2459)
