\qmltype OrthographicCamera \inherits Camera \inqmlmodule QtQuick3D
Defines an Camera with an orthographic projection matrix.
A \l 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 \l Camera in order to visualize its contents.
It is possible to position and rotate the \l Camera like any other spatial \l{QtQuick3D::Node}{Node} in the scene. The \l{QtQuick3D::Node}{Node}'s location and orientation determines where the \l Camera is in the scene, and what direction it is facing. The default orientation of the \l Camera has its forward vector pointing along the negative Z axis and its up vector along the positive Y axis.
The OrthographicCamera is a parallel projection \l Camera, in which parallel lines remain parallel and an object's perceived scale is unaffected by its distance from the \l Camera. Typical use cases for this type of \l Camera are CAD (Computer-Assisted Design) applications and cartography.
The following example creates a OrthographicCamera at position [0, 200, 300] in the scene, and with a 30 degree downward pitch.
