Detailed Description

A model geometric object.

Parent class of model geometric objects.
Inheritors are:
local coordinate system of MbAssistingItem,
MbPointFrame point-frame,
MbWireFrame wireframe,
MbSolid solid,
MbMesh polygonal planar object,
MbInstance instance of object in the local coordinate system,
MbAssembly assembly of objects in the local coordinate system,
MbSpaceInstance instance of three-dimensional object,
MbPlaneInstance instance of a two-dimensional object in the XY-plane of a local coordinate system.
Object contains MbTransactions sequence and ways to construct itself.
Object contains non-geometric properties as MbAttributeContainer attribute container.
The name of an object of a geometric model is represented as a container of simple names. In the beginning of the container there is a SimpleName simple name assigned to object by MbModel geometric model.
If the object doesn't contain other objects, then the container contains one SimpleName simple name. If the object contains other objects (MbAssembly or MbInstance), then the internal objects name is represented as a container with at least two simple names. Number of the elements of an object's name corresponds to the number of levels of objects inclusion relative to the model.

Member Function Documentation

◆ Duplicate()

virtual MbSpaceItem& MbItem::Duplicate ( MbRegDuplicate iReg = NULL) const
pure virtual

Create a copy of the object.

Create a copy of an object using the registrator. Registrator is used to prevent multiple copy of the object. If the object contains references to the other objects, then nested objects are copied as well. It is allowed not to pass registrator into the function. Then new copy of object will be created. While copying of single object or set of not connected objects, it is allowed not to use registrator. Registrator should be used if it is required to copy several connected objects. It is possible, that objects connection is based on the references to common objects. Then, while copying without using of registrator, it is possible to obtain set of copies, that contain references to the different copies of the same nested object, that leads to loss of connection between copies.

Parameters
[in]iReg- Registrator.
Returns
A copy of the object.

Implements MbSpaceItem.

Implemented in MbSolid, MbMesh, MbPointFrame, MbAssembly, MbCollection, MbWireFrame, MbSpaceInstance, MbInstance, MbPlaneInstance, and MbAssistingItem.

◆ Transform()

virtual void MbItem::Transform ( const MbMatrix3D matr,
MbRegTransform iReg = NULL 
)
pure virtual

Convert the object according to the matrix.

Convert the original object according to the matrix using the registrator. If object contains references to the other geometric objects, then nested objects are transformed according to the matrix. Registrator is needed to prevent multiple object copying. It is allowed to use function without registrator, if it is needed to transform single object. If it is needed to transform a set of connected objects, then one should use registrator to prevent repeating transformation of nested objects, because of the possible situation when several objects contain references to the same common objects, that require to be transformed.

Parameters
[in]matr- Transformation matrix.
[in]iReg- Registrator.

Implements MbSpaceItem.

Implemented in MbSolid, MbMesh, MbPointFrame, MbAssembly, MbCollection, MbWireFrame, MbSpaceInstance, MbInstance, MbPlaneInstance, and MbAssistingItem.

◆ Move()

virtual void MbItem::Move ( const MbVector3D to,
MbRegTransform iReg = NULL 
)
pure virtual

Move an object along a vector.

Move an object along a geometric vector using the registrator. If object contains references to the other geometric objects then the move operation is applied to the nested objects. Registrator is needed to prevent multiple copying of the object. It is allowed to use function without registrator, if it is needed to transform a single object. If it is needed to transform a set of connected objects, then one should use registrator to prevent repeating transformation of nested objects, because of the possible situation when several objects contain references to the same common objects, that require to be moved.

Parameters
[in]to- Shift vector.
[in]iReg- Registrator.

Implements MbSpaceItem.

Implemented in MbSolid, MbMesh, MbPointFrame, MbAssembly, MbCollection, MbWireFrame, MbSpaceInstance, MbInstance, MbPlaneInstance, and MbAssistingItem.

◆ Rotate()

virtual void MbItem::Rotate ( const MbAxis3D axis,
double  angle,
MbRegTransform iReg = NULL 
)
pure virtual

Rotate an object around an axis at a given angle.

Rotate an object around an axis at a given angle with the registrator. If object contains references to the other geometric objects then the rotation operation is applied to the nested objects. Registrator is needed to prevent multiple copying of the object. It is allowed to use function without registrator, if it is needed to transform a single object. If it is needed to transform a set of connected objects, then one should use registrator to prevent repeating transformation of nested objects, because of the possible situation when several objects contain references to the same common objects, that require to be rotated.

Parameters
[in]axis- The axis of rotation.
[in]angle- Rotation.
[in]iReg- Registrator.

Implements MbSpaceItem.

Implemented in MbSolid, MbMesh, MbPointFrame, MbAssembly, MbCollection, MbWireFrame, MbSpaceInstance, MbInstance, MbPlaneInstance, and MbAssistingItem.
