Detailed Description

Provides tools to store and retrieve attributes (visualization materials) of TopoDS_Shape in and from TDocStd_Document.

This attribute defines the list of visualization materials (XCAFDoc_VisMaterial) within the whole document. Particular material is assigned to the shape through tree-nodes links.

Visualization materials might co-exists with independent color attributes (XCAFDoc_ColorTool), but beware to preserve consistency between them (it is better using one attribute type at once to avoid ambiguity). Unlike color attributes, list of materials should be managed explicitly by application, so that there is no tool eliminating material duplicates or removing unused materials.
