"NPR" non-photorealistic rendering lab

Write in front

A few days ago I saw a question--about non-realsense graphics or stylized rendering what good books or paper, I just touched some and went inside to answer a bit. After the answer, you suddenly want to do a collection of this in unity, and some simple NPR papers or tutorials are implemented in unity. So these two days to do a bit. I put this project on GitHub (HTTPS://GITHUB.COM/CANDYCAT1992/NPR_LAB) and interested students can go and have a look.

What NPR has implemented

In this two-day work, my main choice is about cartoon rendering some of the earliest papers, such as 1998 's a non-photorealistic Lighting Model for Automatic Technical illustration, This article was first presented in cartoon rendering using tones to simulate the style of illustration. Because the unity package is great, some of the results in the paper I didn't do in unity, and I'll update it when the Unity update is open and more functional.

I will always update this item if you want to see the NPR effect that you can tell me that there is time I will try to achieve.

Every time you update a project, if you add a new render effect, I will also indicate it in the project's README. For example, when I wrote this article, I implemented five simple NPR:

• antialiased Cel Shading

The principle behind

Most of these experiments refer to papers, and a few are based on some tutorials. Most of them use only shader. In the project's readme, I gave the information for each effect reference and the scene name in the project. I was going to write a blog about every effect, but lately I've been writing books and there's a lab work to do, and it's not that much time, so the update will be slow. But in the current realization of several effects, we can find the realization principle from the paper, and shader is not complex.

Written in the last

This project is also purely interested, if you have any comments and suggestions welcome to my message. If you find my implementation is wrong, be sure to tell me.

Finally, I hope you can hava fun~
