Detailed Description

A spline superclass.

This spline can control several dimensions at once.

Member Function Documentation

void csSpline::InsertPoint ( int idx )

Insert a point after some index.

If index == -1 add a point before all others.

void csSpline::SetDimensionValues ( int dim,
float * d )

Set the values for some dimension.

'd' should point to an array containing 'num_points' values. These are the values that will be interpolated. The given array is copied.

void csSpline::SetTimeValues ( float * t )

Set the time values.

't' should point to an array containing 'num_points' values. These values typically start with 0 and end with 1. Other values are also possible the but the values should rise. The given array is copied.
