HOW TEXTURE NODES WORK
|
||||
|
||||
In contrast to Shader nodes, which place a colour into the output
|
||||
stack when executed, Texture nodes place a TexDelegate* there. To
|
||||
obtain a colour value from this, a node further up the chain reads
|
||||
the TexDelegate* from its input stack, and uses tex_call_delegate to
|
||||
retrieve the colour from the delegate.
