Detailed Description

A Camera defines how the content of the 3D scene is projected onto a 2D surface, such as a View3D. A scene needs at least one Camera in order to visualize its contents.

It is possible to position and rotate the Camera like any other spatial Node in the scene. The Node's location and orientation determines where the Camera is in the scene, and what direction it is facing. The default orientation of the Camera has its forward vector pointing along the negative Z axis and its up vector along the positive Y axis.

PerspectiveCamera is the standard Camera type. It gives a realistic projection of the scene, where distant objects are perceived as smaller. The frustum is defined by the fieldOfView property as well as near and far clip planes.

The following example creates a PerspectiveCamera at position [0, 200, 300] in the scene, a field of view of 90 degrees and with a 30 degree downward pitch.

 PerspectiveCamera {
     position: Qt.vector3d(0, 200, 300)
     eulerRotation.x: -30
     fieldOfView: 90
 }
