Detailed Description

Base class for all primitive types in the engine.

A Primitive is the unit of geometry exchanged between nodes. It holds primitive-level attributes (one value per object) and provides the attribute management API shared by all primitive types.

Point attributes are stored on the base class since many primitive types have points. Use hasPoints() to check before accessing them.

Subclasses (e.g. Mesh) add their own attribute owners and geometry.

The documentation for this class was generated from the following files:

src/Engine/Operator/Primitive.h
src/Engine/Operator/Primitive.cpp
