void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
vtkNew< vtkPoints > Surface
Surface to render.
bool DataHasBeenRescaled
true if user-defined data scaling has already been applied, false otherwise.
void SetXRange(float min, float max)
Set the range of the input data for the X dimension.

user-defined data ranges
vtkTable * InputTable
The input table used to generate the surface.
void RescaleData()
Change data values if SetXRange() or SetYRange() were called.
void SetInputData(vtkTable *input, vtkIdType xColumn, vtkIdType yColumn, vtkIdType zColumn) override
Set the input to the surface plot.
float ColumnToX(int columnIndex)
Map a column index to the user-specified range for the X-axis.
void GenerateSurface()
Generate a surface (for OpenGL) from our list of points.
void InsertSurfaceVertex(float *data, float value, int i, int j, int &pos)
Helper function used to setup a colored surface.
float RowToY(int rowIndex)
Map a row index to the user-specified range for the Y-axis.
