Detailed Description

Containers for geometry data.

Attributes are the containers for geometry data in the engine. Each attribute is a single column in the spreadsheet that makes up your geometry. The column has a single name and type. Based on the attribute owner it will also have a value for each element. For example, if the owner is a point then your attribute might be Color, your type might be a vector, and the attribute will have a color value for each point in the mesh. Attributes own the underlying storage for their values, which is contiguous and strongly typed (e.g., ints, floats, vectors, bools). This allows a single attribute class to store data regardless of the type without templates. Attributes cannot be read or written from by themselves. For that an attribute handle is required, (see enzo::ga::AttributeHandle).

Note

Values are strongly typed; invalid type combinations are guarded both at compile time (via handles) and at runtime (defensive checks).
