这是 OpenGL 课程的最终团队项目——互动式广告牌云。我们不仅实现了论文中的原始想法，还发展了自己的改进思路。通过使用多个广告牌来表示复杂的物体，例如树木，并采用三角形投影等技术细节，使算法更加高效和直观。

This is the final project for my OpenGL class, which is a group work.

We not only implement the original idea of the paper, and we also develop our own ideas as improvements.

The basic idea of Billboard Cloud is quite simple: using multiple billboards to represent a complex object, as a tree. The key to this algorithm is projection of triangles. The idea in paper is to project the nearest triangles to a billboard.

We have made our new algorithm interactive. You can indicate the ratio (num. of boards / num. of triangles) or board number, so that you can see the difference interactively. Of course, we have to eliminate the constrains for distance (nearest triangles).

The picture below shows our work:
