Represent a continuous scalar range of values.
vtkm::Range
is a helper class for representing a range of floating point values from a minimum value to a maximum value. This is specified simply enough with a Min
and Max
value.
Range
also contains several helper functions for computing and maintaining the range.

inline 
Returns the center of the range.
Center
computes the middle value of the range. If the range is empty, NaN is returned.

inline 
Determines if a value is within the range.
Contains
returns true if the give value is within the range, false otherwise. Contains
treats the min and max as inclusive. That is, if the value is exactly the min or max, true is returned.

inline 
Expand range to include a value.
This version of Include
expands the range just enough to include the given value. If the range already includes this value, then nothing is done.

inline 
Expand range to include other range.
This version of Include
expands this range just enough to include that of another range. Essentially it is the union of the two ranges.

inline 
Determine if the range is valid (i.e.
has at least one valid point).
IsNonEmpty
return true if the range contains some valid values between Min
and Max
. If Max
is less than Min
, then no values satisfy the range and IsNonEmpty
returns false. Otherwise, return true.
IsNonEmpty
assumes Min
and Max
are inclusive. That is, if they are equal then true is returned.

inline 
Returns the length of the range.
Length
computes the distance between the min and max. If the range is empty, 0 is returned.

This is a nondestructive form of Include
