public class PerspectiveCamera extends Camera
This camera defines a viewing volume for a perspective projection;
a truncated right pyramid.
The fieldOfView
value can be used to change viewing volume.
This camera is always located at center of the scene and looks along the
positive z-axis. The coordinate system defined by this camera has its
origin in the upper left corner of the panel with the Y-axis pointing
down and the Z axis pointing away from the viewer (into the screen).
In the default camera, where fixedEyeAtCameraZero is false, the Z value
of the eye position is adjusted in Z such that the projection matrix generated
using the specified fieldOfView
will produce units at
Z = 0 (the projection plane), in device-independent pixels, matches that of
the ParallelCamera.
When the Scene is resized,
the objects in the scene at the projection plane (Z = 0) will stay the same size,
but more or less content of the scene is viewable.
If fixedEyeAtCameraZero is true, the eye position is fixed at (0, 0, 0)
in the local coordinates of the camera. The projection matrix is generated
using the specified fieldOfView
and the projection volume is mapped
onto the viewport (window) such that it is stretched over more or fewer
device-independent pixels at the projection plane.
When the Scene is resized,
the objects in the scene will shrink or grow proportionally,
but the visible portion of the content is unchanged.
We recommend setting fixedEyeAtCameraZero to true if you are going to transform (move) the camera. Transforming the camera when fixedEyeAtCameraZero is set to false may lead to results that are not intuitive.
Note that this is a conditional feature. See
ConditionalFeature.SCENE3D
for more information.
