Instance Property


A dictionary of GLSL source code snippets for customizing the shader programs provided by SceneKit.


optional var shaderModifiers: [SCNShaderModifierEntryPoint : String]? { get set }


The dictionary’s keys must be from the set of constants described in Shader Modifier Entry Point Keys. Each key represents a possible entry point in SceneKit’s shader programs, whose corresponding value is an NSString object containing a shader source code snippet to be included in the shader program at that entry point.

See Use Shader Modifiers to Extend SceneKit Shading in the protocol overview for a complete discussion of shader modifiers.
