BroadLeaf: Real-Time Cinematic Rendering of Large-Scale Forests

Realistic real-time rendering of large-scale forests is an important, yet difficult, problem—due to the massive number of plant-leaf geometries. In this session, Yixin Hu, Senior Graphics Researcher at Tencent America, proposes a new method: BroadLeaf. For rendering large-scale plane leaves with cinematic quality in real time.

Their rendered plant leaves have explicit geometries (triangle meshes) and are single-leaf interactable. To reach this result, BroadLeaf generates and handles the Level of Details (LODs) of tree leaves automatically and provides a smooth and efficient LOD transition. The leaves from different levels are organized hierarchically, which accelerates and makes more precise the LOD selection and culling for reducing the rendering geometry complexity.

Learn more about how BroadLeaf is faster and more robust than existing methods, and how it can be easily integrated into game engines or directly used in real-time rendering applications.


Attendees will learn about a new method for realistic real-time rendering of forests, BroadLeaf, for rendering interactive forest scenes with cinematic quality.

Intended Audience

This is for game engine developers and developers—particular those working to render large-scale forests in real-time—as well as game scene designers.
