Detailed Description

The Amr source creates a dataset similar to VTK's vtkRTAnalyticSource.

This class generates a predictable structured dataset with a smooth yet interesting set of scalars, which is useful for testing and benchmarking.

The Execute method creates a complete structured dataset that have a point field names 'scalars'

The scalars are computed as:

MaxVal * Gauss + MagX * sin(FrqX*x) + MagY * sin(FrqY*y) + MagZ * cos(FrqZ*z)

The dataset properties are determined by:

• Minimum/MaximumExtent: The logical point extents of the dataset.
• Spacing: The distance between points of the dataset.
• Center: The center of the dataset.

The scalar functions is control via:

• Center: The center of a Gaussian contribution to the scalars.
• StandardDeviation: The unscaled width of a Gaussian contribution.
• MaximumValue: Upper limit of the scalar range.
• Frequency: The Frq[XYZ] parameters of the periodic contributions.
• Magnitude: The Mag[XYZ] parameters of the periodic contributions.

By default, the following parameters are used:

• Extents: { -10, -10, -10 } --> { 10, 10, 10 }
• Spacing: { 1, 1, 1 }
• Center: { 0, 0, 0 }
• StandardDeviation: 0.5
• MaximumValue: 255
• Frequency: { 60, 30, 40 }
• Magnitude: { 10, 18, 5 }
