My latest project is an App called "FiltSketch", which generate an sketched image from a picture.
The core algorithm is an image to vector converter based on a shape evolution using Hill Climbing method. It is a kind of pattern searching in a image by trial and error.
There is an already a famous App in the Mac App Store: Primitive for macOS. The App is well built and very impressive.
The author also has published the source code of the core algorihm: Rrimitive on GitHub (go lang)

My app is using the same algorithm and using the vector data to draw a paint like image. (TBD)

Anyway, here are some screenshots of my first attempt of implementing the algorithm in C++11, this is so far I have achieved and satisfied with as a first phase.

Galaxy Spatioplotter 1.04

Galaxy Spatioplotter (macOS) 1.04 is now available. More colorful Galaxy!

Galaxy Spatioplotter@Mac App Store

More color options to make it better looking, even though it might not reflect the actual color. I'm still struggling to create a "smoke" kind of effect of dust lane. The app uses GLSL for the volume rendering, thus it is kind of heavy program. The simulation itself should be stable.

Adobe Muse

I have started working on so called "cornerstone page" for my apps, and I chose to try to use Adobe Muse.
It's pretty easy to use, as long as you follow certain rule of the behavior of the software.
Here are the links:

Some thought:
  • Overall easy to use. Consistent UI throughout Adobe products.
  • "Assets" concept is important - prepare images beforehand, and use "Place" to put images.
  • If I use "Pin", then contents won't flow any more. This is a huge issue when I try to center any objects. I'm not sure what I'm doing wrong.
  • To make an image "pin" to the center of the page, use text box and paste an image as an inline image, and use "wrap"/'text align" to make it center. Regular "Pin to page" won't work, but this works.

Muse Essential Training by Dani Beaumont on was great and very useful/helpful.

Galaxy Spatioplotter improvement

I've been working on improving the appearance of galaxies generated by Galaxy Spatioplotter.
It was OK before using accurate B-V color, but not visually attractive.
So, I added a little more "color" to it.
I'm hoping to release this option soon.
