Derived classes are responsible for returning if a given type is an acceptable input.
Implemented in HeightToNormalNodeGlsl, and BlurNode.

Implemented in HeightToNormalNodeGlsl, and BlurNode.
|
overridevirtual |
Create shader variables needed for the implementation of this node (e.g.
uniforms, inputs and outputs). Used if the node requires input data from the application.
Reimplemented from ShaderNodeImpl.
|
protectedvirtual |
Get input which is used for sampling.
If there is none then a null pointer is returned.
