| void Ogre::RotationalSpline::addPoint | ( | const Quaternion & | p | ) |
Adds a control point to the end of the spline.
| void Ogre::RotationalSpline::clear | ( | void | ) |
Clears all the points in the spline.
| unsigned short Ogre::RotationalSpline::getNumPoints | ( | void | ) | const |
Gets the number of control points in the spline.
| const Quaternion& Ogre::RotationalSpline::getPoint | ( | unsigned short | index | ) | const |
Gets the detail of one of the control points of the spline.
| Quaternion Ogre::RotationalSpline::interpolate | ( | Real | t, |
| bool | useShortestPath = true |
||
| ) |
Returns an interpolated point based on a parametric value over the whole series.
| t | Parametric value. |
| useShortestPath | Defines if rotation should take the shortest possible path |
| Quaternion Ogre::RotationalSpline::interpolate | ( | unsigned int | fromIndex, |
| Real | t, | ||
| bool | useShortestPath = true |
||
| ) |
Interpolates a single segment of the spline given a parametric value.
| fromIndex | The point index to treat as t=0. fromIndex + 1 is deemed to be t=1 |
| t | Parametric value |
| useShortestPath | Defines if rotation should take the shortest possible path |
| void Ogre::RotationalSpline::recalcTangents | ( | void | ) |
Recalculates the tangents associated with this spline.
| void Ogre::RotationalSpline::setAutoCalculate | ( | bool | autoCalc | ) |
Tells the spline whether it should automatically calculate tangents on demand as points are added.
| autoCalc | If true, tangents are calculated for you whenever a point changes. If false, you must call reclacTangents to recalculate them when it best suits. |
| void Ogre::RotationalSpline::updatePoint | ( | unsigned short | index, |
| const Quaternion & | value | ||
| ) |
Updates a single point in the spline.
