Constructor & Destructor Documentation
|
Create a spline with d dimensions and p points.
|
|
Destroy the spline.
|
Member Function Documentation
|
Calculate internal values for this spline given some time value.
Implemented in csCubicSpline, and csBSpline. |
|
Get the index of the current point we are in (valid after Calculate()).
Reimplemented in csPath. Definition at line 126 of file spline.h. Referenced by csPath::GetCurrentIndex(). |
|
Get the number of dimensions.
|
|
Get the value for some dimension.
Definition at line 112 of file spline.h. Referenced by csPath::GetForwardVector(), csPath::GetPositionVector(), and csPath::GetUpVector(). |
|
Get the values for some dimension.
|
|
After calling Calculate() you can use this to fetch the value of some dimension.
Implemented in csCubicSpline, and csBSpline. |
|
Get the number of points.
Definition at line 55 of file spline.h. Referenced by csPath::Length(). |
|
Get one time point.
Definition at line 89 of file spline.h. Referenced by csPath::GetTime(). |
|
Get the time values.
|
|
Insert a point after some index. If index == -1 add a point before all others. |
|
Remove a point at the index.
|
|
Set a value for some dimension.
Referenced by csPath::SetForwardVector(), csPath::SetPositionVector(), and csPath::SetUpVector(). |
|
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. |
|
Set one time point.
Referenced by csPath::SetTime(). |
|
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. |
