| − | {{documentation/modulename}} module allows to output a filtered transform node based on an tracker input (transform node). Tracking sensors are really usefull to track surgical tools, robots, patient motion, etc... . However, the data imported in 3D Slicer from these devices are often noisy. In order to reduce this noise and being able to smoothly control some object, such as 3D Slicer camera, the {{documentation/modulename}} module will apply a low-pass filter on input data. The cut-off frequency (i.e. the smoothing parameter) is adjustable by the user.
| |
| − | It is important to notice that filters induce delay, and the smoother the motion is, the bigger the delay between the raw data and the filtered position will be.

| − | Here comes a description what the module is good for. Explain briefly how it works and point to the [[documentation/{{documentation/version}}/Modules/{{documentation/modulename}}#References|references]] giving more details on the algorithm.

| − | If you are documenting a CLI, the description should be extracted from the corresponding XML description. This could be done automatically using the following wiki template:<pre>{{documentation/{{documentation/version}}/module-description}}

| |
| − | The {{documentation/modulename}} module could be used in any situation requiring stable tracking data and not requiring a "real-time" information. Indeed, applying a filter on raw data will induce a delay (depending on choosen parameters) on the filtered position/orientation.
| |
| − | An example could be to drive Slicer's virtual camera. Having some noise on the transformation driving the camera will cause the camera to "shake" which could be really distracting and make it difficult to see what is happening in the scene. By filtering this raw data, we could smooth the camera motion.

| − | The GUI of the {{documentation/modulename}} module contains 4 elements:
| |
| − | * Input Transform. This is the raw data, usually raw tracker data, represented by a vtkMRMLLinearTransformNode
| |
| − | * Output Transform. This is the filtered transform represented also by a vtkMRMLLinearTransformNode. This node can be created directly from the list
| |
| − | * Filter checkbox. This checkbox turn on/off the filtering
| |
| − | * Smoothing slider. This slider control the smoothing parameter. In the left, really smooth, with quiet important delay. In the right, faster (almost no delay), but noisier.
