XPRESSO

XPRESSO is a node-based system to create custom expressions. The API is defined in c4d_graphview.h.

• GvOperatorData is a plugin hook for custom nodes.
• XPressoTag (Texpresso) stores a node system and returns the GvNodeMaster.
• GvNodeMaster represents a node system, gives access to the stored nodes and is used to create new nodes.
• GvNode represents a single node.
• GvWorld gives access to global utility functions.
• GvNodeGUI is a custom GUI element used to display XPRESSO node systems.
