3D surface plot.
virtual void PrintSelf(ostream &os, vtkIndent indent)
Methods invoked by print to print information about the object including superclasses.
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.
vtkNew< vtkLookupTable > LookupTable
The lookup table used to color the surface by height (Z dimension).
float XMinimum

virtual void SetInputData(vtkTable *input, vtkIdType xColumn, vtkIdType yColumn, vtkIdType zColumn)
vtkTable * InputTable
The input table used to generate the surface.
std::vector< vtkVector3f > Surface
Surface to render.
void RescaleData()
Change data values if SetXRange() or SetYRange() were called.
virtual bool Paint(vtkContext2D *painter)
Paint event for the XY plot, called whenever the chart needs to be drawn.
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.
vtkIdType NumberOfVertices
The number of vertices in the surface.
virtual void SetInputData(vtkTable *input)
Set the input to the surface plot.
vtkNew< vtkUnsignedCharArray > Colors
This array indicates how the surface should be colored.
void SetYRange(float min, float max)
Set the range of the input data for the Y dimension.
vtkIdType NumberOfColumns
The number of columns in the input table.
int ColorComponents
The number of components used to color the surface.
