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()).
Definition at line 138 of file spline.h. Referenced by csPath::GetCurrentIndex(). |
|
Get the number of dimensions.
|
|
Get the value for some dimension.
Definition at line 113 of file spline.h. Referenced by csPath::GetForwardVector(), csPath::GetPositionVector(), and csPath::GetUpVector(). |
|
Get the values for some dimension.
|
|
Gets the values of the control point at index idx. Caller is responsible for invoking `delete[]' on returned array when no longer needed. |

|
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. |
|
Sets the values of the control point at index idx.
|
|
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. |
