A3DMiscCascadedAttributesPush(A3DMiscCascadedAttributes *pAttr, const A3DRootBaseWithGraphics *pBase, const A3DMiscCascadedAttributes *pFather) A3DStatusA3DMiscCascadedAttributesPush(A3DMiscCascadedAttributes* pAttr, constA3DRootBaseWithGraphics* pBase, constA3DMiscCascadedAttributes* pFather)Computes the result of cascaded attribute propagation from a parent node.
2.0In the context of a model file node hierarchy,*cascaded*describes the way an application using HOOPS Exchange will resolve conflicting attributes. Attributes are propagated downstream, by overriding current attributes with the parent node’s ones according to specific inheritance rules defined in:ref:Bit Field for Behavior on Graphics <group__a3d__graphicsbits>.
Although properties propagation can be manually applied if those rules are known, HOOPS Exchange provides``#A3DMiscCascadedAttributesPush``as a convenience function.
#A3DMiscCascadedAttributesPushcomputes the result of propagating attributes from``pFather``to``pBase``and writes them into``pAttr``, which data can then be retrieves using``#A3DMiscCascadedAttributesGet``.pBasecan be any instance of``#A3DTopoFace``#A3DTopoShell,``#A3DTopoConnex``,``#A3DRiRepresentationItem``,``#A3DAsmPartDefinition``or``#A3DAsmProductOccurrence``.Parameters
pAttr: A handle to the resulting cascaded attributes
pBase: The child node the attributes are computed from
pFather: The attributes held by the parent node
Returns
A3D_SUCCESSor an error code in case of failure.
