vtkElevationFilter - generate scalars along a specified direction

Super Class: vtkDataSetToDataSetFilter

Description:

vtkElevationFilter is a filter to generate scalar values from a dataset. The scalar values lie within a user specified range, and are generated by computing a projection of each dataset point onto a line. The line can be oriented arbitrarily. A typical example is to generate scalars based on elevation or height above a plane.

Methods:

• vtkElevationFilter ();
• char *GetClassName ();
• void PrintSelf (ostream &os, vtkIndent indent);
• vtkElevationFilter *New ();
• void SetLowPoint (float , float , float );
• void SetLowPoint (float a[3]);
• float *GetLowPoint ();
• void SetHighPoint (float , float , float );
• void SetHighPoint (float a[3]);
• float *GetHighPoint ();
• void SetScalarRange (float , float );
• void SetScalarRange (float a[2]);
• float *GetScalarRange ();
• void Execute ();

Detailed Method Descriptions:

• vtkElevationFilter *New ();

Construct object with LowPoint=(0,0,0) and HighPoint=(0,0,1). Scalar range is (0,1).

• void SetLowPoint (float , float , float );
• void SetLowPoint (float a[3]);
• float *GetLowPoint ();

Define one end of the line (small scalar values).

• void SetHighPoint (float , float , float );
• void SetHighPoint (float a[3]);
• float *GetHighPoint ();

Define other end of the line (large scalar values).

• void SetScalarRange (float , float );
• void SetScalarRange (float a[2]);
• float *GetScalarRange ();

Specify range to map scalars into.
