Hi, I am happy to announce my first asset has just been released on Asset Store. Check it out at https://www.assetstore.unity3d.com/en/#!/content/86803 Its an asset that will get you up and running with any Coloring project in a matter of minutes. Its a component I created for my coloring app (https://play.google.com/store/apps/details?id=pl.ayground.coloringbook). Well tested on both Android and iOS. There is no need to prepare coloring pages - any B&W PNG will do. On top of the Coloring script you will also get an implementation of Bradley Local Threshold to process a photo of a handmade coloring image. Sample App (Coloring Book Template) provided - give it a try at https://play.google.com/store/apps/details?id=pl.ayground.coloringalgorithm Add a set of pages, a color pallette of your choice and you are good to conquer the world with your coloring book. Any question - let me know here on the forum. PS. It works on Texture2D level so any Texture2D (and derivatives) usage ideas are possible.
