How to add new images ?

Hi, how to add images and get coordinate in .txt file

[llisper]

There are many ways to get a triangulated image. I mainly use 2 ways to do it, it's very simple since the tools I used are open source tools.

1. Google for a tool call "ImageTriangulator", it can help you process a normal image into a triangulated image by setting discrete points on the image, after you've done, it will uses Delaunay Triangulation Algorithm to process the points you've set and generated the triangulated image. Since you've set all the points yourself so you already know the coordinates of them, and the tool can export the coordinates for you, that is where the "animal004.txt" file came from. Now you got the image and the points, you can use the same algorithm to acquire the triangulated date structure in unity, and you've got everything you need to finally generate the meshes. About Delaunay Triangulation Algorithm, which is a well-known algorithm and you can easily find papers on the internet explaining how it works. And here is a implementation on Github: https://github.com/PouletFrit/csDelaunay.git
2. Check out this website: https://snorpey.github.io/triangulation , this is a online image triangulation tool, you can play with it, it's also a open source project. It can export .svg file for you, which you can parse directly to get the coordinates information you need.

So as you can see, I didn't implement any of these tools myself, and the images in this project are all converted from normal images. If you have only an already triangulated image and you don't have any extra information about it(if it's not a .svg file), I think you need a much more complex algorithm to do that, I can't help you with that right now -.-
