Detailed Description

generate scalars along a specified direction.

Date:

2000/12/10 20:08:36

Revision:

1.32

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.

Member Function Documentation

virtual const char* vtkElevationFilter::GetClassName (    )  [virtual]

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkDataSetToDataSetFilter.

int vtkElevationFilter::IsTypeOf (  const char *    type )  [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkDataSetToDataSetFilter.

virtual int vtkElevationFilter::IsA (  const char *    type )  [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkDataSetToDataSetFilter.

vtkElevationFilter* vtkElevationFilter::SafeDownCast (  vtkObject *    o )  [static]

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkDataSetToDataSetFilter.

void vtkElevationFilter::PrintSelf (  ostream &    os, vtkIndent    indent )  [virtual]

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes. Reimplemented from vtkSource.

vtkElevationFilter* vtkElevationFilter::New (    )  [static]

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

virtual void vtkElevationFilter::SetLowPoint (  float   , float   , float    )  [virtual]

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

virtual void vtkElevationFilter::SetLowPoint (  float   [3] )  [virtual]

virtual float* vtkElevationFilter::GetLowPoint (    )  [virtual]

virtual void vtkElevationFilter::GetLowPoint (  float    data[3] )  [virtual]

virtual void vtkElevationFilter::SetHighPoint (  float   , float   , float    )  [virtual]

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

virtual void vtkElevationFilter::SetHighPoint (  float   [3] )  [virtual]

virtual float* vtkElevationFilter::GetHighPoint (    )  [virtual]

virtual void vtkElevationFilter::GetHighPoint (  float    data[3] )  [virtual]

virtual void vtkElevationFilter::SetScalarRange (  float   , float    )  [virtual]

Specify range to map scalars into.

void vtkElevationFilter::SetScalarRange (  float   [2] )

virtual float* vtkElevationFilter::GetScalarRange (    )  [virtual]

virtual void vtkElevationFilter::GetScalarRange (  float    data[2] )  [virtual]

void vtkElevationFilter::operator= (  const vtkElevationFilter &    )  [inline, protected]

Definition at line 87 of file vtkElevationFilter.h.

void vtkElevationFilter::Execute (    )  [protected, virtual]

Reimplemented from vtkSource.
