String art Visual comparison

String art Visual comparison

This is interesting. I have been working on android String art app(https://play.google.com/store/apps/details?id=com.shaktam.stringart) for a while. String art apps' has two challenges, first is the algorithm itself, 2nd is the visualizer. Even if the algorithm produces the best string art sequence, if the visualizer code(architecture) is not done correctly, the output looks bad. In my previous post, someone shared a github link. I ran the code as python script later. The middle image is the result at 200 nails and 6000 lines. From the visual I was blown away. later I converted the sequence format and imported to the mobile app(BTW you can import sequence in txt if the format is correct or supported). The right side image is the result. Now it looks different from the original python visual. Why they do look different? the answer is variable opacity per line used in the python script. The same sequence looks messy(soft edge) in the app. Even though my app let's user to change opacity, it's architecture doesn't support the variable alpha. The right side image is just for reference, It is generated at 200 nails 5500 lines. BTW which one looks better to you?

String art rendering

I have been working on an android app, it is one those, string art generators, one challenge, I am facing, is to make the preview or render same as the actual string art. In the app, I added the board size and string thickness option. The app calculates and shows the density (visual). I hope the math is correct and it mimics the physical one. Black/white works fine, but the issue is in the color mode, CYMK. The current architecture of color is layer method, first cyan, then yellow, magenta, Black. I used opaque lines, but with that, the output visual can't produce accurate color, like red(it looks dead). So I used blend_multiply mode with the opaque in the code, this way it shows vibrant color output. But what I am worried is, how accurate does this present a physical colored string art. This render is done at 70cm board size and 0.2 mm string thickness,
