Camera QML Type

Holds the current aspect ratio of the camera.

Holds the current bottom of the camera.

This property is only relevant when projectionType is CameraLens.OrthographicProjection.

Holds the current exposure of the camera.

The default value is 0.0.

The MetalRoughMaterial in Qt 3D Extras is currently the only provided material that makes use of camera exposure. Negative values will cause the material to be darker, and positive values will cause it to be lighter.

Custom materials may choose to interpret the value differently.

Holds the current camera far plane of the camera. Objects that are farther from the camera than the farPlane will not be rendered.

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

Along with aspectRatio, this property determines how much of the scene is visible to the camera. In that respect you might think of it as analogous to choosing a wide angle (wide horizontal field of view) or telephoto (narrow horizontal field of view) lens, depending on how much of a scene you want to capture.

fieldOfView is only relevant when projectionType is CameraLens.PerspectiveProjection.

Holds the current left of the camera.

This property is only relevant when projectionType is CameraLens.OrthographicProjection.

Holds the current camera near plane of the camera. Objects that are closer to the camera than the nearPlane will not be rendered.

Holds the current position of the camera in coordinates relative to the parent entity.

Holds the current projection matrix of the camera.

Holds the type of the camera projection. The default value is CameraLens.PerspectiveProjection.

• CameraLens.OrthographicProjection - Parallel lines appear parallel. Objects appear the same size regardless of distance.

• CameraLens.PerspectiveProjection - Parallel lines appear to meet in the distance. Objects appear to shrink the farther they are from the camera.

• CameraLens.FrustumProjection

• CameraLens.CustomProjection

Holds the current right of the camera.

This property is only relevant when projectionType is CameraLens.OrthographicProjection.

Holds the current top of the camera.

This property is only relevant when projectionType is CameraLens.OrthographicProjection.

Holds the current up vector of the camera in coordinates relative to the parent entity.

The up vector indicates which direction the top of the camera is facing. Think of taking a picture: after positioning yourself and pointing the camera at your target, you might rotate the camera left or right, giving you a portrait or landscape (or angled!) shot. upVector allows you to control this type of movement.

Holds the current view center of the camera in coordinates relative to the parent entity.

Intuitively, the viewCenter is the location the camera is pointing at.

Holds the camera's view vector in coordinates relative to the parent entity.

This vector decribes the displacement from the camera (position) to its target (viewCenter).

Adjusts the pan angle of the camera by angle in degrees.

Adjusts the camera pan about view center by angle in degrees on axis.

Adjusts the camera pan about view center by angle in degrees.

Adjusts the camera pan about view center by angle in degrees on axis.

Returns the calculated pan rotation in relation to the angle in degrees taken in to adjust the camera's pan or left/right rotation on the Y axis.

Adjusts the camera roll by angle in degrees.

Adjusts the camera roll about view center by angle in degrees.

Returns the calculated roll rotation in relation to the angle in degrees taken in to adjust the camera's roll or lean left/right rotation on the Z axis.

Rotates the camera with the use of a Quaternion in q.

Rotates the camera about the view center with the use of a Quaternion in q.

Returns the calculated rotation in relation to the angle in degrees and chosen axis taken in.

Adjusts the tilt angle of the camera by angle in degrees.

Adjusts the camera tilt about view center by angle in degrees.

Returns the calculated tilt rotation in relation to the angle in degrees taken in to adjust the camera's tilt or up/down rotation on the X axis.

Translates the camera's position and its view vector by vLocal in local coordinates. The option allows for toggling whether the view center should be translated.

• Camera.TranslateViewCenter

• Camera.DontTranslateViewCenter

Translates the camera's position and its view vector by vWorld in world coordinates. The option allows for toggling whether the view center should be translated.

• Camera.TranslateViewCenter

• Camera.DontTranslateViewCenter
