Elevation (ElevationFilter)
Create point attribute array by projecting points onto an elevation vector.
The Elevation filter generates point scalar values for an input dataset along a specified direction vector.



The Input menu allows the user to select the data set to which this filter will be applied. Use the Scalar range entry boxes to specify the minimum and maximum scalar value to be generated. The Low Point and High Point define a line onto which each point of the data set is projected. The minimum scalar value is associated with the Low Point, and the maximum scalar value is associated with the High Point. The scalar value for each point in the data set is determined by the location along the line to which that point projects.

PropertyDescriptionDefault Value(s)Restrictions
High Point
(HighPoint)
This property defines the other end of the direction vector (large scalar values). 0 0 1

The coordinate must lie within the bounding box of the dataset. It will default to the maximum in each dimension.

 
Input
(Input)
This property specifies the input dataset to the Elevation filter.  

The selected object must be the result of the following: sources (includes readers), filters.

The selected dataset must be one of the following types (or a subclass of one of them): vtkDataSet.

 
Low Point
(LowPoint)
This property defines one end of the direction vector (small scalar values). 0 0 0

The coordinate must lie within the bounding box of the dataset. It will default to the minimum in each dimension.

 
Scalar Range
(ScalarRange)
This property determines the range into which scalars will be mapped. 0 1
