Samweow Posted July 25, 2020 Share Posted July 25, 2020 Is there any way to specify a gradient that spreads consistently from the center of a curved shape? Such that the gradient would be darkest along this red line and lightest at the edges of the shape? Here's a drawing example of what it would look like kind of.

Pšenda Posted July 25, 2020 Share Posted July 25, 2020 Try draw this with Pen, soft Brush and with pressure.

thomaso Posted July 26, 2020 Share Posted July 26, 2020 Gradients are just straight at the moment. They can neither be curved nor follow a path or more than an angle. Gradients lack Bezier. Curving gradients feels currently like infinity: I may come close but never reach it.

firstdefence Posted July 26, 2020 Share Posted July 26, 2020 You could use strokes and blurs.

firstdefence Posted July 26, 2020 Share Posted July 26, 2020 A softer blend can also be achieved, so I created the horn shape, added some coloured curves with a pressure profile applied so that the stroke tapered at the bottom and blurred them. that effect can be seen in the post above. To get a finer transition I duplicated the horn shape and deleted the the nested strokes, then placed the original horn shape with the nested strokes and their blur fx into the new duplicate horn shape, this acts as a container/clipping mask for the next level of blur that I added to the original horn shape that contains the blurred strokes. This sounds complex but actually isn’t. horns.afdesign Quote iMac 27" 2019 Somona 14.3.1, iMac 27" Affinity Designer, Photo & Publisher V1 & V2, Adobe, Inkscape, Vectorstyler, Blender, C4D, Sketchup + more...

GarryP Posted July 26, 2020 Share Posted July 26, 2020 In addition to the advice above, my attached video shows one technique that might be useful in some circumstances, maybe after some tweaking. (Apologies if I’ve accidentally copied techniques from above but some of those posts don’t show many details.) Putting a gradient along a curve within a shape is more difficult than it seems at first because to get the required result you have to be absolutely sure about what you want it to do at all points along the curve. In other words, how should the gradient ‘fall-off’ at each point along the curve within the shape at different widths of the shape and how should it reduce. Tricky to get right. 2020-07-26_08-39-24.mp4 Samweow 1 Quote Link to comment Share on other sites More sharing options...
firstdefence Posted July 26, 2020 Share Posted July 26, 2020 Never think to use the outline fx but good tip, the only concern I have is it’s constant width, even with a pressure curve applied the contour still stays a constant width. If there was a Pressure curve as part of the outline fx contour option, that would be an interesting option.

GarryP Posted July 26, 2020 Share Posted July 26, 2020 The idea just popped into my head but I agree that some kind of ‘pressure curve’ for the outline width could be useful, otherwise the technique I posted has limited utility for what I think Samweow wants. I guess the best solution probably depends on exactly what they want and how much thought they have put into what they want. (I often get ideas that I think should be easy but end up being difficult to do in practice because I haven’t thought enough about the details, especially when it comes to things like shadows – e.g. simulating 3D in 2D.)

firstdefence Posted July 26, 2020 Share Posted July 26, 2020 After some playing around the three nested curves creating the colour, highlight and shadow do not require blurring although it can add subtly to the effect, As with all of this trying out different techniques is half the creative fun. 😊 PS. It’s nice to bounce idea’s around and maybe come to a workable solution.

G13RL Posted July 26, 2020 Share Posted July 26, 2020 I tried another way, inserting a brushstroke with pressure into the original stroke. For a simple and regular shape (the crescent on the right) I proceeded in the same way. firstdefence 1 Quote Link to comment Share on other sites More sharing options...

GarryP Posted July 26, 2020 Share Posted July 26, 2020 (edited) Another quick bit of experimentation got me what’s in my attached image (and document) by using a Textured Image Brush (using the gradient-filled layer at the top-right as the brush). I’m sure it could be done better with some tweaking. brush-experiment-for-gradient-on-curve.afdesign Edited July 26, 2020 by GarryP Added document.

firstdefence Posted July 26, 2020 Share Posted July 26, 2020 Yes It’s the banding as the straight gradient curves that stands out although it’s an effect in itself 😊 Quote iMac 27" 2019 Somona 14.3.1, iMac 27" Affinity Designer, Photo & Publisher V1 & V2, Adobe, Inkscape, Vectorstyler, Blender, C4D, Sketchup + more...

GarryP Posted July 26, 2020 Share Posted July 26, 2020 Yeah, I didn’t like the banding either. Here are a few more experiments using different-width brushes which use an ellipse and no bounding curve (brush on the top, curve using brush on bottom). Still not quite what I would want, but getting there slowly. Samweow 1 Quote Link to comment Share on other sites More sharing options...
