| |
| − | Most frequently Transform module is used for these scenarios:
| |
| − | | |
| − | * Manual Registration: You can insert a transformation node into your scene, and in the Data module drag a volume or a model under it,
| |
| − | making them children of the transformation node. After that any changes to the transformation matrix of this node will be applied to the display of children volumes and models.

| − | How to programmatically apply a transform to a transformable node:
| |
| − | vtkNew<[http://slicer.org/doc/html/classvtkMRMLLinearTransformNode.html vtkMRMLLinearTransformNode]> transformNode;
| |
| − | scene->AddNode(transformNode.GetPointer());
| |
| − | ...
| |
| − | vtkNew<vtkMatrix4x4> matrix;
| |
| − | ...
| |
| − | transform->SetAndObserveMatrixTransformToParent( matrix.GetPointer() );
| |
| − | ...
| |
| − | vtkMRMLVolumeNode* transformableNode = ...; // or vtkMRMLModelNode*...
| |
| − | transformableNode->SetAndObserveTransformNodeID( transformNode->GetID() );
| |
| − | | |
| − | Because a ''transform'' node is also a ''transformable'' node, it is possible to concatenate transforms with each others:
| |
| − | [http://slicer.org/doc/html/classvtkMRMLLinearTransformNode.html vtkMRMLLinearTransformNode*] transformNode = ...;
| |
| − | [http://slicer.org/doc/html/classvtkMRMLLinearTransformNode.html vtkMRMLLinearTransformNode*] transformNode2 = ...;
| |
| − | transformNode2->SetAndObserveTransformNodeID( transformNode->GetID() );
| |
| − | ...
| |
| − | transformable->SetAndObserveTransformNodeID( transformNode2->GetID() );
| |
| − | | |
| − | ===Events===
| |
| − | When a transform node is observed by a transformable node, [http://slicer.org/doc/html/classvtkMRMLTransformableNode.html#ace1c30fc9df552543f00d51a20c038a6a4993bf6e23a6dfc138cb2efc1b9ce43b vtkMRMLTransformableNode::TransformModifiedEvent] is fired on the transformable node at observation time.
| |
| − | Anytime a transform is modified, vtkCommand::ModifiedEvent is fired on the transform node and [http://slicer.org/doc/html/classvtkMRMLTransformableNode.html#ace1c30fc9df552543f00d51a20c038a6a4993bf6e23a6dfc138cb2efc1b9ce43b vtkMRMLTransformableNode::TransformModifiedEvent] is fired on the transformable node.
