What is Shader?

Shader is a set of instructions that determine how an object will be rendered on a screen. It includes information about the object’s color, lighting, and other properties that affect its appearance.

Shaders are used in 3D visualization to create realistic images of objects. They are often used in computer games to give characters and environments a more lifelike look. Shaders can also be used to create special effects, such as explosions or fire.

There are many different types of shaders, each designed for a specific purpose. Some shaders are very simple, while others are quite complex. The type of shader you use will depend on the type of object you are trying to render and the effect you want to achieve.
