Structure​

Although the algorithms are very straightforward, I know how hard it could be to learn and reproduce a research work. That's why I created this tutorial, designed with a smooth learning curve and providing the seamless development environment.

You should start with the Basic part, which covers the basics of the rendering methods. Remember to read the articles in the Basic part in its original order, or you may miss something important. Next, select your favorite topics to learn. I will list extra prerequisites at the very beginning of each article.

Wish you happy learning!

Research Tip

To demonstrate your research work about brush rendering, select vector drawings have variable radius or pen pressure data. Regular vector drawing datasets don't contain them.

Tessellation-based Rendering

There were works trying to tessellate a stroke and render it with GPU. -You can find them in several papers and online articles.

Paper and article list

To begin with, I would recommend Rye Terrell's Instanced Line Rendering to learn -several simple tessellation methods. -They may inspire some approaches to optimize the performance of the articulated algorithms.

In this article, I will compare the tessellation-based algorithms with articulated algorithms in detail.
