Detailed Description

transform based on per-point or per-cell weighting functions.

vtkWeightedTransformFilter is a filter that can be used to "skin" structures and to create new and complex shapes. Unlike a traditional transform filter (which has one transform for a data set) or an assembly (which has one transform per part or group of parts), a weighted transform produces the weighted sum of transforms on a per-point or per-cell basis.

Each point or cell in the filter's input has an attached DataArray that contains tuples of weighting functions, one per point or cell. The filter also has a set of fixed transforms. When the filter executes, each input point/cell is transformed by each of the transforms. These results are weighted by the point/cell's weighting factors to produce final output data.

Linear transforms are performance-optimized. Using arbitrary transforms will work, but performance may suffer.

As an example of the utility of weighted transforms, here's how this filter can be used for "skinning." Skinning is the process of putting a mesh cover over an underlying structure, like skin over bone. Joints are difficult to skin because deformation is hard to do. Visualize skin over an elbow joint. Part of the skin moves with one bone, part of the skin moves with the other bone, and the skin in the middle moves a little with each.

Weighted filtering can be used for a simple and efficient kind of skinning. Begin with a cylindrical mesh. Create a FloatArray with two components per tuple, and one tuple for each point in the mesh. Assign transform weights that linear interpolate the distance along the cylinder (one component is the distance along the cylinder, the other is one minus that distance). Set the filter up to use two transforms, the two used to transform the two bones. Now, when the transforms change, the mesh will deform so as to, hopefully, continue to cover the bones.

vtkWeightedTransformFilter is also useful for creating "strange and complex" shapes using pinching, bending, and blending.

Warning: Weighted combination of normals and vectors are probably not appropriate in many cases. Surface normals are treated somewhat specially, but in many cases you may need to regenerate the surface normals.; Cell data can only be transformed if all transforms are linear.

◆ SetWeightArray()

virtual void vtkWeightedTransformFilter::SetWeightArray ( const char * )

virtual

WeightArray is the string name of the DataArray in the input's FieldData that holds the weighting coefficients for each point.

The filter will first look for the array in the input's PointData FieldData. If the array isn't there, the filter looks in the input's FieldData. The WeightArray can have tuples of any length, but must have a tuple for every point in the input data set. This array transforms points, normals, and vectors.

◆ GetWeightArray()

WeightArray is the string name of the DataArray in the input's FieldData that holds the weighting coefficients for each point.

The filter will first look for the array in the input's PointData FieldData. If the array isn't there, the filter looks in the input's FieldData. The WeightArray can have tuples of any length, but must have a tuple for every point in the input data set. This array transforms points, normals, and vectors.

◆ SetTransformIndexArray()

virtual void vtkWeightedTransformFilter::SetTransformIndexArray ( const char * )

virtual

TransformIndexArray is the string name of the DataArray in the input's FieldData that holds the indices for the transforms for each point.

These indices are used to select which transforms each weight of the DataArray refers. If the TransformIndexArray is not specified, the weights of each point are assumed to map directly to a transform. This DataArray must be of type UnsignedShort, which effectively limits the number of transforms to 65536 if a transform index array is used.
