Abstract
After learning, we can use ray tracing to implement some simple scenarios. Today we will discuss three basic light sources in graphics: Direction light source, point light source, and spotlight.
Different from the use of existing APIs, this time we will use C ++ to implement it step by step from theory to practice.
Prerequisites
At the teacher's suggestion, I replaced the graphic engine with SDL, and the final rendering effect was much better
In the Create Panel/create light panel, we can create five types of lights. As shown in the following illustration:
