Member Data Documentation

m_component_index

ON_COMPONENT_INDEX ON_ObjRef_IRefID::m_component_index

If this ON_ObjRef_IRefID is the first entry in the ON_ObjRef.m__iref[] array, then it references a "real" piece of geometry (not a nested instance reference).
If the reference is to a subobject of the real piece of geometry, then m_component_index records the subobject index. In all other cases, m_component_index is not set.

m_evp

ON_ObjRefEvaluationParameter ON_ObjRef_IRefID::m_evp

If this ON_ObjRef_IRefID is the first entry in the ON_ObjRef.m__iref[] array, then it references a "real" piece of geometry (not a nested instance reference).
If there is an evaluation parameter for the geometry, it is saved in m_evp. In all other cases, m_evp is not set.

m_geometry_xform

ON_Xform ON_ObjRef_IRefID::m_geometry_xform = ON_Xform::ZeroTransformation

m_geometry_xform is the transformation to map the base geometry to world coordinates. If the instance reference is not nested, then m_geometry_xform = m_iref_xform. If the instance reference is nested, then m_geometry_xform = m_iref_xform * .... * T1 where the Ts are the transformations from the children.

m_idef_geometry_index

int ON_ObjRef_IRefID::m_idef_geometry_index = 0

m_geometry_index is the index of the uuid of the pertinent piece of geometry in the ON_InstanceRef.m_object_uuid[] array. This index is identical to the index of the geometry's CRhinoObject in the CRhinoInstanceDefinition.m_objects[] array.

m_idef_uuid

ON_UUID ON_ObjRef_IRefID::m_idef_uuid = ON_nil_uuid

m_idef_uuid is the instance definition id stored in ON_InstanceRef.m_instance_definition_uuid and ON_InstanceDefinition.m_uuid.

m_iref_uuid

ON_UUID ON_ObjRef_IRefID::m_iref_uuid = ON_nil_uuid

m_iref_uuid is the CRhinoInstanceObject's uuid stored in its ON_3dmObjectAttributes.m_uuid.

m_iref_xform

ON_Xform ON_ObjRef_IRefID::m_iref_xform = ON_Xform::ZeroTransformation

m_iref_xform is the value stored in ON_InstanceRef.m_xform.
