What are the light sources in three.js?In Three.js, the light source has a base class of Three.light (hex), which accepts 16 binary colors as parameters to initialize the color of the light source, such as we want to define a green light source, which can be defined as:var New Three. Light (0x00FF00);And as the 3d engine three.js, this base class is difficult to meet our requirements, so we also need to inherit the base class of the more diverse light source:In addition to this base class light

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: Recommended reading: 3d Lighting Learning Basics 3d Lighting Explanation Target spot: Targeted spotlight. The way you create it is very similar to how you create a camcorder. The target spotlight has a target point in addition to a starting point. The starting point indicates where the l
