Gran Turismo 7 includes the feature of dynamic time and weather changes to create a more realistic driving experience and the excitement of dramatic racing action. To achieve this, the team at Polyphony Digital implemented a new sky dome rendering system.
Sky dome has two main parts: the sky and clouds. The team studied a highly accurate atmospheric model for sky rendering and developed a highly efficient run-time look-up table. Furthermore, they implemented noise-based modeling and lighting with ray marching for cloud rendering.
Through this session, attendees will gain insight into a method for rendering the sky dome based on a higher quality atmospheric model—compared to conventional methods and its use for real-time rendering. In particular, a fundamental technique of atmospheric scattering simulations, the importance of measurement-based atmospheric composition, and accurate Mie scattering will be discussed in detail.
The audience will gain insight into the real-time rendering of photorealistic skies based on physical atmospheric models, as well as problems and solutions when integrating them into real games.
This is for mid-to-experienced graphics programmers interested in rendering sky and atmosphere in real time.
