Smooth tool

[VectorStyler]

@Boldline I will fix these issues

@Boldline https://imgbox.com/uREIHee5 - There it is. There are two gifs. One done through percentages. The other through factors. Both are better than what's available in Illustrator.

I actually compared the curve smoothing algorithm across Vectorstyler, Illustrator, Inkscape, Affinity, PhotoLine and Xara. Here's how they performed:

1. Poorest of them all: Affinity. Affinity does not have a separate function for this. It is included into the node delete function. "Fit to curve delete node" Completely destroys the curve.

Here's the result. It is a completely different curve altogether.

2. Vectorstyler: The simplifier tool is very poor in it's current form. It does not do what it is supposed to do per the tool tip.

3. Inkscape: Simplify path produces erratic results. There's no way to compare before/after. It is comparable to Illustrator in performance.

4. PhotoLine: Curve Optimisation also destroys curve form if the factor is raised by more than a few points. Practically useless.

5. Illustrator: Smooth tool is again drag and pray. Hopeless for except the most simple scenarios. This is why Astute Plugins still sell. Astute Plugins do this brilliant.

6. Xara: It still has - after 30 years - the best algorithm for curve optimisation! https://imgbox.com/501rb5PJ - Here's the gif of my experiment. Reducing 50 nodes to a mere 4. Notice the ability to see before/after in real-time and course correct. I love that!

Send me some examples where this did not work.

[Daniel]

@VectorStyler: https://imgbox.com/KTPwu6su - Here's an example. The smoothing is rather weak. I didn't have a tablet at hand so it is done with a mouse. But still.

@Daniel Can you send me the file with that shape?

@Daniel The best brush tool for smoothing is Corel Draw. I even mentioned it to @VectorStyler - if it could do that, it would be perfect, both smoothing and smudging/pinching.

[Daniel]

@Yoshy: I tried it. And I have to say that Xara still beats it. It is quite intelligent in that it knows I am trying to retain the form of the curve, whilst removing the unnecessary nodes. Therefore, its able to insert a node at the average point and maintain curve form. It also gives a real-time preview of what is going to happen, something Corel does not do.

Most curves without inflection spots (point) should be approximated by a second degree Bezier. 1 inflexion → 3rd degree and then it should be arbitrary for a Smooth + Minimalistic function.
A Smooth function typically changes the shape. A Minimizing function should retain the shape.

Square has hard corners → Smooth → all corners get rounded but also the sides gets bulged for "smooth" to happen. It (smoothing) is not the same as just rounding the corners and it shouldn't be. Maybe moving the rounding corner outside (negative numbers) the corner should make that corner more like an 'Eifel tower' type of corner and the sides to go concave?

@Daniel very smooth and very control in corel draw https://sendvid.com/jylqv7jd

@Yoshy
I think we might be misunderstanding each other here. When I say smoothing, I mean creating the most optimal curve with the minimal number of nodes without sacrificing the overall form of the curve. What CorelDraw seems to be doing is to change the form of the curve itself based on the strength of the settings.

In that case, smoothing can still be done by factors like in PhotoLine. Because I don't think a brush is the best way to achieve this. You have to repeatedly parse the curve with the brush to do it. Whereas if you did via a dialogue box, you can opt to do this either for the whole curve, or sections of the curve: Like here below:

We might all be on different wavelengths! From what I see and understand, VS ( @VectorStyler is a genius) already has the two main tools we would use for simplifying and smoothing out paths: the "path simplifier tool" for direct use by the user scrubbing the curve and the "simplify path" panel for more broad smoothing of entire objects. With all respect to the developer, both tools still need some improvement to best work their different roles. From what everyone has contributed in this thread and in other related posts and @VectorStyler's focus on bugs and improvement, both tools will get to their best version

[Daniel]

@Boldline fair point.

[Boldline]

@Daniel I love the ideas you've shared for the "simplify path" tool. I may end up using it a lot more as those ideas get added as @VectorStyler sees fit.
I appreciate that VS has options for designers who need precise and exact edits to their curved paths and another option for those who are going for what looks good by sight for their art and are not needing something technical
