Shaders are written in OpenGL Shading Language and compiled. The compiled programs are executed on the GPU. The compiled programs are executed on the GPU. OpenGL Shading Language ( GLSL ) is a high-level shading language with a syntax based on the C programming language .
Shaders are most commonly used to produce lit and shadowed areas in the rendering of 3D models. Another use of shaders is for special effects, even on 2D images, (e.g., a photo from a webcam). The unaltered, unshaded image is on the left, and the same image has a shader applied on the right.
A plot of the smoothstep(x) and smootherstep(x) functions, using 0 as the left edge and 1 as the right edgeSmoothstep is a family of sigmoid-like interpolation and clamping functions commonly used in computer graphics, [1] [2] video game engines, [3] and machine learning.

Light that is reflected on a relatively smooth surface gives rise to a specular reflection. This kind of reflection is especially strong for metal surfaces. Models that describe the perceived brightness due to specular reflection include: Phong; Blinn–Phong; Cook–Torrance (microfacets) Ward anisotropic
Smooth Uses the same color for every pixel in a face – usually the color of the first vertex: Smooth shading uses linear interpolation of either colors or normals between vertices Edges appear more pronounced than they would on a real object because in reality almost all edges are somewhat round: The edges disappear with this technique
Conventional smooth lighting values are calculated for each pixel and then quantized to a small number of discrete shades to create the characteristic "flat look", where the shadows and highlights appear as blocks of color rather than being smoothly mixed in a gradient.
The Blinn–Phong reflection model, also called the modified Phong reflection model, is a modification developed by Jim Blinn to the Phong reflection model. [1]Blinn–Phong is a shading model used in OpenGL and Direct3D's fixed-function pipeline (before Direct3D 10 and OpenGL 3.1), and is carried out on each vertex as it passes down the graphics pipeline; pixel values between vertices are ...
