/// \brief Compute the range of the data in an array handle.
|
|
///
|
|
/// Given an `ArrayHandle`, this function computes the range (min and max) of
|
|
/// the values in the array. For arrays containing Vec values, the range is
|
|
/// computed for each component.
|
|
///
|
|
/// This method optionally takes a `vtkm::cont::DeviceAdapterId` to control which
|
|
/// devices to try.
|
|
///
|
|
/// The result is returned in an `ArrayHandle` of `Range` objects. There is
|
|
/// one value in the returned array for every component of the input's value
|
|
/// type.
|
|
///
|
|
/// Note that the ArrayRangeCompute.h header file contains only precompiled overloads
|
|
/// of ArrayRangeCompute. This is so that ArrayRangeCompute.h can be included in
|
|
/// code that does not use a device compiler. If you need to compute array ranges
|
|
/// for arbitrary `ArrayHandle`s not in this precompiled list, you need to include
|
|
/// ArrayRangeComputeTemplate.h. This contains a templated version of ArrayRangeCompute
|
|
/// that will compile for any `ArrayHandle` type not already handled.
