IfcSurfaceStyleShading

Definition from ISO/CD 10303-46:1992: The surface style rendering allows the realistic visualization of surfaces refering to rendering techniques based on the laws of physics and mathematics.

Definition from IAI: The entity IfcSurfaceStyleShading allows for colour information used for shading, whereas subtypes provide data for more sophisticated rendering techniques. The surface colour is used for colouring or simple shading of the assigned surfaces.

NOTE Corresponding STEP entity: surface_style_rendering. Please refer to ISO/IS 10303-46:1994 for the final definition of the formal standard. No rendering method is defined for each surface style (such as constant, colour, dot or normal shading), therefore the attribute rendering_method has been omitted.

HISTORY: New entity in Release IFC 2x.
