|
Abstract base class of interpolants over parametric samples.<br /><br />
|
||
|
|
|
||
|
|
The parameter domain is one dimensional, typically the time or a path along a curve defined by the data.<br /><br />
|
||
|
|
|
||
|
|
The sample values can have any dimensionality and derived classes may apply special interpretations to the data.<br /><br />
|
||
|
|
|
||
|
|
This class provides the interval seek in a Template Method, deferring the actual interpolation to derived classes.<br /><br />
|
||
|
|
|
||
|
|
Time complexity is `O(1)` for linear access crossing at most two points and `O(log N)` for random access,
|
||
|
|
where *N* is the number of positions.<br /><br />
