Detailed Description

Attribute storing Material definition for visualization purposes.

Visualization material provides extended information about how object should be displayed on the screen (albedo, metalness, roughness - not just a single color as in case of XCAFDoc_Color). It is expected to correlate with physical material properties (XCAFDoc_Material), but not necessarily (like painted/polished/rusty object).

The document defines the list of visualization materials via global attribute XCAFDoc_VisMaterialTool, while particular material assignment to the shape is done through tree-nodes links. Therefore, XCAFDoc_VisMaterialTool methods should be used for managing XCAFDoc_VisMaterial attributes.

Visualization material definition consists of two options: Common and PBR (for Physically Based Rendering). Common material definition is an obsolete model defined by very first version of OpenGL graphics API and having specific hardware-accelerated implementation in past (like T&L). PBR metallic-roughness model is closer to physical material properties, and intended to be used within physically-based renderer.

For compatibility reasons, this attribute allows defining both material models, so that it is up-to Data Exchange and Application deciding which one to define and use for rendering (depending on viewer capabilities). Automatic conversion from one model to another is possible, but lossy (converted material will not look the same).

Within Data Exchange, different file formats have different capabilities for storing visualization material properties from simple color (STEP, IGES), to common (OBJ, glTF 1.0) and PBR (glTF 2.0). This should be taken into account while defining or converting document into one or another format - material definition might be lost or disturbed.
