Why You Should Learn Shader Development
For the visual arts, shading is a key technique. Shading creates the illusion of a 3D appearance on a 2D medium. The feeling of the artwork, which is created by the artist, is directly related to how it is shaded.
Shading in real life is a phenomenon that is the result of the interaction between light and matter. An artist uses this phenomenon in his or her artwork to create the atmosphere.
If you want to shade an object in computer screen, you need to use shaders. You may want to create photo realistic or unrealistic images or impressive visual effects. Then you have to deal with shaders.
Most game engines come with built-in shaders. And most game developers use these built-in shaders. If you cannot write your own shader code, then you are very restricted to create the visual experience you want.
Things That You Can Create with Shaders
Beyond the increase of photorealism of the images on the screen, you can create any kind of visual experience you would like to create like non-realistic looking images or special effects. In addition to them, you can use the power of the parallel design of GPUs to make expensive calculations very efficiently using compute shaders. You can manipulate the model geometry of the objects, also.
