| Overview: | Graphics engineers from the Halo 4 team discuss the problem of generating and rendering high quality lighting from user-generated content (UGC). Visual features such as hemispherical occlusion and full-scene directional shadows (which may be too costly to generate in real-time) can be generated and compressed into lightmaps on the fly by utilizing UV space GPU rasterization. This talk will provide a general overview of the challenges that can be solved with just-in-time lighting, as well as a detailed explanation of how it was applied to Halo's map editor, Forge. |
