The common interface for SceneKit objects that support multipass rendering using SCNTechnique objects.
Mac Catalyst 13.0+Beta
Techniques let you specify approaches to rendering a scene that involves multiple drawing passes. For example, you might create a technique that uses a shader program to postprocess a rendered scene on the GPU, creating special effects such as color grading, screen-space ambient occlusion, or motion blur. Different SceneKit objects support techniques in different ways, summarized in Table 1.
Methods you can implement to use your own custom Metal or OpenGL drawing code to render content for a node.
