This is the main application of all games or real-time computer graphics . What is real-time , In computer graphics, real-time is generated every second 30 Sub picture or 30 frame . Reaching this level can be called real-time , Otherwise we will call him offline . This real-time graphics Institute is widely used in rasterization methods .

The geometric

How to represent a smooth curve ？ How to represent a surface ？ How to get more complex surfaces by subdividing simple surfaces

Ray tracing

Mainly used in animation and movies , It can generate higher quality pictures

◎ Light is emitted from the camera through each pixel

         Calculate intersections and shadows

         Continue to reflect light , Until they hit the light

Animation / simulation

Keyframe animation
