Description
set_object_model_3d_attribset_object_model_3d_attribSetObjectModel3dAttribSetObjectModel3dAttribSetObjectModel3dAttribset_object_model_3d_attrib sets the standard attributes or the
extended attributes given in AttribNameAttribNameAttribNameAttribNameattribNameattrib_name of a 3D object model
ObjectModel3DObjectModel3DObjectModel3DObjectModel3DobjectModel3Dobject_model_3d to the values in AttribValuesAttribValuesAttribValuesAttribValuesattribValuesattrib_values and returns
a 3D object model with the new attribute values in ObjectModel3DOutObjectModel3DOutObjectModel3DOutObjectModel3DOutobjectModel3DOutobject_model_3dout.
set_object_model_3d_attribset_object_model_3d_attribSetObjectModel3dAttribSetObjectModel3dAttribSetObjectModel3dAttribset_object_model_3d_attrib is identical to
set_object_model_3d_attrib_modset_object_model_3d_attrib_modSetObjectModel3dAttribModSetObjectModel3dAttribModSetObjectModel3dAttribModset_object_model_3d_attrib_mod with the exception that it creates a
new 3D object model and leaves the original 3D object model unchanged.
It is possible to attach the values of extended attributes to
already existing standard attributes of the 3D object model by setting the
parameter AttachExtAttribToAttachExtAttribToAttachExtAttribToAttachExtAttribToattachExtAttribToattach_ext_attrib_to. For standard attributes,
AttachExtAttribToAttachExtAttribToAttachExtAttribToAttachExtAttribToattachExtAttribToattach_ext_attrib_to is ignored.
If the attributes in AttribNameAttribNameAttribNameAttribNameattribNameattrib_name do not exist, they are created if
possible.
If already existing attributes are set, the length of AttribValuesAttribValuesAttribValuesAttribValuesattribValuesattrib_values
must match the existing attribute values. In this case the existing attribute
values are replaced.
If extended attributes are attached to already existing standard
attributes with AttachExtAttribToAttachExtAttribToAttachExtAttribToAttachExtAttribToattachExtAttribToattach_ext_attrib_to, the length of AttribValuesAttribValuesAttribValuesAttribValuesattribValuesattrib_values
must match the existing attribute values.

indices of the points of the first polygon. The next value
(input value n+1) contains the number m of the points of the

and height of the respective image. The following n
values (input values 2,3,..,n+1, with n being the number
of 3D points) represent the row coordinates of the n points
given in image coordinates. The next n input values (input
values n+2,n+3,..,n*2+1) represent the column coordinates of the

Extended attributes
Extended attributes are attributes, that can be derived from standard
attributes by special operators (e.g., distance_object_model_3ddistance_object_model_3dDistanceObjectModel3dDistanceObjectModel3dDistanceObjectModel3ddistance_object_model_3d),
or user-defined attributes.
The names of extended attributes are arbitrary, but must start with
the prefix '&'"&""&""&""&""&", e.g., '&my_attrib'"&my_attrib""&my_attrib""&my_attrib""&my_attrib""&my_attrib".
Extended attributes can have an arbitrary number of floating point
values.
Extended attributes can be attached to already existing standard attributes
of the 3D object model by setting the parameter AttachExtAttribToAttachExtAttribToAttachExtAttribToAttachExtAttribToattachExtAttribToattach_ext_attrib_to.
The following values of AttachExtAttribToAttachExtAttribToAttachExtAttribToAttachExtAttribToattachExtAttribToattach_ext_attrib_to are possible:
- 'object'"object""object""object""object""object" or []:
If this value is set, the extended attribute specified in
AttribNameAttribNameAttribNameAttribNameattribNameattrib_name is associated to the 3D object model as a whole.
The number of values specified in AttribValuesAttribValuesAttribValuesAttribValuesattribValuesattrib_values is not restricted.
- 'points'"points""points""points""points""points":
If this value is set, the extended attribute specified in
AttribNameAttribNameAttribNameAttribNameattribNameattrib_name is associated to the 3D points of the object model.
The number of values specified in AttribValuesAttribValuesAttribValuesAttribValuesattribValuesattrib_values must be the
same as the number of already existing 3D points.
- 'triangles'"triangles""triangles""triangles""triangles""triangles":
If this value is set, the extended attribute specified in
AttribNameAttribNameAttribNameAttribNameattribNameattrib_name is associated to the triangles of the object model.
The number of values specified in AttribValuesAttribValuesAttribValuesAttribValuesattribValuesattrib_values must be the
same as the number of already existing triangles.
- 'polygons'"polygons""polygons""polygons""polygons""polygons":
If this value is set, the extended attribute specified in
AttribNameAttribNameAttribNameAttribNameattribNameattrib_name is associated to the polygons of the object model.
The number of values specified in AttribValuesAttribValuesAttribValuesAttribValuesattribValuesattrib_values must be the
same as the number of already existing polygons.
- 'lines'"lines""lines""lines""lines""lines":
If this value is set, the extended attribute specified in
AttribNameAttribNameAttribNameAttribNameattribNameattrib_name is associated to the lines of the object model.
The number of values specified in AttribValuesAttribValuesAttribValuesAttribValuesattribValuesattrib_values must be the
same as the number of already existing lines.
Attention
If multiple attributes are given in AttribNameAttribNameAttribNameAttribNameattribNameattrib_name,
AttribValuesAttribValuesAttribValuesAttribValuesattribValuesattrib_values is divided into sub-tuples of equal length.
Each sub-tuple is then assigned to one attribute.
E.g., if AttribNameAttribNameAttribNameAttribNameattribNameattrib_name and AttribValuesAttribValuesAttribValuesAttribValuesattribValuesattrib_values are set to
AttribNameAttribNameAttribNameAttribNameattribNameattrib_name := ['&attrib1','&attrib2','&attrib3']["&attrib1","&attrib2","&attrib3"]["&attrib1","&attrib2","&attrib3"]["&attrib1","&attrib2","&attrib3"]["&attrib1","&attrib2","&attrib3"]["&attrib1","&attrib2","&attrib3"],
AttribValuesAttribValuesAttribValuesAttribValuesattribValuesattrib_values := [0.0,1.0,2.0,3.0,4.0,5.0],
the following values are assigned to the individual attributes:
'&attrib1'"&attrib1""&attrib1""&attrib1""&attrib1""&attrib1" = [0.0,1.0],
'&attrib2'"&attrib2""&attrib2""&attrib2""&attrib2""&attrib2" = [2.0,3.0],
'&attrib3'"&attrib3""&attrib3""&attrib3""&attrib3""&attrib3" = [4.0,5.0].
Consequently,
it is not possible to set multiple attributes of different
lengths in one call.
set_object_model_3d_attribset_object_model_3d_attribSetObjectModel3dAttribSetObjectModel3dAttribSetObjectModel3dAttribset_object_model_3d_attrib stores the input AttribValuesAttribValuesAttribValuesAttribValuesattribValuesattrib_values
unmodified in the 3D object model. Therefore, special attention must
be paid to the consistency of the input data, as most of the operators
expect consistent 3D object models.
