The spaceships of the future world visit the earth and feel the structure inside the spaceship. 1. Using high dynamic range images (HDRI) HDRI is an image with a very wide range of brightness, and its way of recording brightness is different from traditional pictures. It records brightness information in a direct corresponding way. It can be said to record lighting information in the picture environment, so we can Use this image to "illuminate" the scene. 2. Scan model Quixel software is used. Quixel series software is a game and film creation software based on the material and model library generated by real 3D scanning, which can provide super realistic model support for this project. 3. Distance field technology: is an approximate simulation of the model, which can simulate the information stored in the volume texture. It generates a texture for each model, which is equivalent to a volume texture, and uses this information to approximate the simulation model, which can be very realistic and accurate for shadows.
