## Detailed Description

## Property Documentation

aspectRatio : real

Holds the current aspect ratio of the camera lens.

bottom : real

Holds the current bottom plane of the camera lens.

farPlane : real

Holds the current near plane of the camera lens.

fieldOfView : real

Holds the current field of view of the camera lens in degrees.

left : real

Holds the current left plane of the camera lens.

nearPlane : real

Holds the current near plane of the camera lens.

projectionMatrix : matrix4x4 `[read-only]`
