Shaders in Sprite Kit facilitate
SKScenenode to appear with a special, customized, drawing behavior. This can be achieved by creating the
SKShader objects and assigning a custom OpenGL ES fragment shader.
If a custom shader (the
SKShader object) needs to provide a uniform shader, then you need to create one or more
SKUniform objects and associate them with your shader objects. Shader programs are primarily divided into:
Let's discuss about both of these in detail:
