So, imagine you are an artist and you want to paint something on a canvas. You need different colors and brushes to do that, right? But what if you want to paint a 3D object on your computer screen? You cannot use regular paint brushes and colors for that.
That is where high-level shading language comes in. It is a computer language that helps artists (or programmers) to create 3D graphics by telling the computer how to shade different parts of the object.
It is like having a special set of brushes and colors made just for 3D graphics. The high-level shading language tells the computer things like, how shiny or smooth a surface should look, where shadows and highlights should be placed, and how light should bounce off surfaces.
By using different commands in the high-level shading language, you can create amazing 3D graphics that look almost like real-life objects. Just like how an artist can create a beautiful painting by using a set of special tools and techniques, programmers can create stunning 3D graphics using high-level shading language.
