## Detailed Description

generate scalars along a specified direction

Date:
  2002/01/22 15:29:18

Revision:
  1.37

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]`

| 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 vtkTypeRevisionMacro 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 vtkTypeRevisionMacro found in vtkSetGet.h. Reimplemented from vtkDataSetToDataSetFilter.

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

| 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 vtkDataSetToDataSetFilter.

vtkElevationFilter* vtkElevationFilter::New | ( |  | ) | `[static]`

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

| Specify range to map scalars into.

void vtkElevationFilter::SetScalarRange | ( | float | [2] | ) |

| Specify range to map scalars into.

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

| Specify range to map scalars into.

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

| Specify range to map scalars into.

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

| This method is the old style execute method Reimplemented from vtkSource.
