|
Base class for nodes in a visual shader graph.

|
Visual shader graphs consist of various nodes. Each node in the graph is a separate object and they are represented as a rectangular boxes with title and a set of properties. Each node has also connection ports that allow to connect it to another nodes and control the flow of the shader.
