AI Technical Summary

Technical Problem

Existing physically based atmospheric rendering formulas suffer from high computational costs and low rendering efficiency when simulating planetary atmospheres.

Method used

Using Billboard technology, the initial planet model, the first facet, and the light attenuation vector are obtained. The display parameters of the facet, including shape, transparency, color, and light emission pattern, are adjusted to determine the third facet. The initial planet model and the third facet are then moved to the same position and combined to obtain the target planet model.

Benefits of technology

While ensuring the rendering effect of the atmosphere, the number of calculations was reduced, rendering efficiency was improved, and performance consumption was saved.
