The `Tangle` source would create a point field generically named `nodevar`. This name was not indicitive of the data or its source. Thus, the output point field has been renamed `tangle`. The `Tangle` source was also creating a cell field (named `cellvar`). This field was really just a mirror of the cell indices (counting from 0 on up). This field has been removed from the input. If you want such a field, you can now use the `GenerateIds` filter to add it to any data set.

* @brief The Tangle source creates a uniform dataset.
|
|
*
|
|
* This class generates a predictable uniform grid dataset with an
|
|
* interesting point field, which is useful for testing and
|
|
* benchmarking.
|
|
*
|
|
* The Execute method creates a complete structured dataset of a
|
|
* resolution specified in the constructor that is bounded by the
|
|
* cube in the range [0,1] in each dimension. The dataset has a
|
|
* point field named 'tangle' computed with the following formula
|
|
*
|
|
* x^4 - 5x^2 + y^4 - 5y^2 + z^4 - 5z^2
