Detailed Description

OrbitCamera action.

Orbits the camera around the center of the screen using spherical coordinates.

Member Function Documentation

static OrbitCamera* create ( float  t,
float  radius,
float  deltaRadius,
float  angleZ,
float  deltaAngleZ,
float  angleX,
float  deltaAngleX 
)
static

Creates a OrbitCamera action with radius, delta-radius, z, deltaZ, x, deltaX.

Duration in seconds. The start radius. The delta radius. The start angle in Z. The delta angle in Z. The start angle in X. The delta angle in X. An OrbitCamera.

void sphericalRadius ( float *  r,
float *  zenith,
float *  azimuth 
)

Positions the camera according to spherical coordinates.

The spherical radius. The spherical zenith. The spherical azimuth.

virtual void startWithTarget ( Node target)
overridevirtual

Called before the action start.

It will also set the target.

A certain target.

Reimplemented from ActionCamera.

virtual void update ( float  time)
overridevirtual

Called once per frame.

time is a value between 0 and 1.

For example:

  • 0 Means that the action just started.
  • 0.5 Means that the action is in the middle.
  • 1 Means that the action is over.

    A value between 0 and 1.

Reimplemented from Action.
