Computer GraphicsAre graphics created using computers and, more generally, the representation and manipulation of image data by a computer.

 

What is shader?

A shader is a small program or set of algorithms that determines how 3-D surface properties of objects are rendered, and how light interacts with the object within a 3-D computer program. newergpus calculate shaders where previusly it was an algorithm calculated by the CPU.

Shaders are simple programs that describe the traits of either a vertex or a pixel. vertex Shaders describe the traits (Position, texture coordinates, colors, etc .) of a vertex, while pixel shaders describe the traits (color, Z depth and Alpha value) of a pixel.

As the major graphic software library: OpenGL, DirectX 3D, they provide three type shaders: vertex, pixel and geometry shader.

What is rendering?

RenderingIs the process of generating an image from a model, by means of computer programs. the model is a description of Three-dimen1_objects in a strictly defined language or data structure. it woshould contain geometry, viewpoint, texture, lighting, and shading information.

 

What is shading?

In computer graphics,ShadingRefers to the process of altering a color based on its angle to lights and its distance from lights to create a photorealistic effect. Shading is running med during the rendering process.
