interpolate a series of cameras to update a new camera
This class is used to interpolate a series of cameras to update a specified camera. Either linear interpolation or spline interpolation may be used. The instance variables currently interpolated include position, focal point, view up, view angle, parallel scale, and clipping range.
To use this class, specify the type of interpolation to use, and add a series of cameras at various times "t" to the list of cameras from which to interpolate. Then to interpolate in between cameras, simply invoke the function InterpolateCamera(t,camera) where "camera" is the camera to be updated with interpolated values. Note that "t" should be in the range (min,max) times specified with the AddCamera() method. If outside this range, the interpolation is clamped. This class copies the camera information (as compared to referencing the cameras) so you do not need to keep separate instances of the camera around for each camera added to the list of cameras to interpolate.
- Warning
- The interpolator classes are initialized the first time InterpolateCamera() is called. Any later changes to the interpolators, or additions to the list of cameras to be interpolated, causes a reinitialization of the interpolators the next time InterpolateCamera() is invoked. Thus the best performance is obtained by 1) configuring the interpolators, 2) adding all the cameras, and 3) finally performing interpolation.
-
Currently position, focal point and view up are interpolated to define the orientation of the camera. Quaternion interpolation may be added in the future as an alternative interpolation method for camera orientation.
