~SimpleSpline () | |
void | addPoint (const Vector3 &p) |
Adds a control point to the end of the spline. | |
const Vector3 & | getPoint (unsigned short index) const |
Gets the detail of one of the control points of the spline. | |
unsigned short | getNumPoints (void) const |
Gets the number of control points in the spline. | |
void | clear (void) |
Clears all the points in the spline. | |
void | updatePoint (unsigned short index, const Vector3 &value) |
Updates a single point in the spline. | |
Vector3 | interpolate (Real t) |
Returns an interpolated point based on a parametric value over the whole series. | |
Vector3 | interpolate (unsigned int fromIndex, Real t) |
Interpolates a single segment of the spline given a parametric value. | |
void | setAutoCalculate (bool autoCalc) |
Tells the spline whether it should automatically calculate tangents on demand as points are added. | |

void Ogre::SimpleSpline::addPoint | ( | const Vector3 & | p | ) |
Adds a control point to the end of the spline.
const Vector3& Ogre::SimpleSpline::getPoint | ( | unsigned short | index | ) | const |
Gets the detail of one of the control points of the spline.
unsigned short Ogre::SimpleSpline::getNumPoints | ( | void | ) | const |
Gets the number of control points in the spline.
void Ogre::SimpleSpline::clear | ( | void | ) |
Clears all the points in the spline.
void Ogre::SimpleSpline::updatePoint | ( | unsigned short | index, | |
const Vector3 & | value | |||
) |
Updates a single point in the spline.
Returns an interpolated point based on a parametric value over the whole series.
t | Parametric value. |
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 |
void Ogre::SimpleSpline::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::SimpleSpline::recalcTangents | ( | void | ) |
Recalculates the tangents associated with this spline.
