Camera3D¶
Inherits: Node3D < Node < Object
Inherited By: XRCamera3D
Camera node, displays from a point of view.
Description¶
Camera3D is a special node that displays what is visible from its current location. Cameras register themselves in the nearest Viewport node (when ascending the tree). Only one camera can be active per viewport. If no viewport is available ascending the tree, the camera will register in the global viewport. In other words, a camera just provides 3D display capabilities to a Viewport, and, without one, a scene registered in that Viewport (or higher viewports) can't be displayed.

Enumerations¶
enum ProjectionType:
ProjectionType PROJECTION_PERSPECTIVE = 0
Perspective projection. Objects on the screen becomes smaller when they are far away.
ProjectionType PROJECTION_ORTHOGONAL = 1
Orthogonal projection, also known as orthographic projection. Objects remain the same size on the screen no matter how far away they are.
ProjectionType PROJECTION_FRUSTUM = 2
Frustum projection. This mode allows adjusting frustum_offset to create "tilted frustum" effects.
enum KeepAspect:
KeepAspect KEEP_WIDTH = 0
Preserves the horizontal aspect ratio; also known as Vert- scaling. This is usually the best option for projects running in portrait mode, as taller aspect ratios will benefit from a wider vertical FOV.
KeepAspect KEEP_HEIGHT = 1
Preserves the vertical aspect ratio; also known as Hor+ scaling. This is usually the best option for projects running in landscape mode, as wider aspect ratios will automatically benefit from a wider horizontal FOV.
enum DopplerTracking:
DopplerTracking DOPPLER_TRACKING_DISABLED = 0
Disables Doppler effect simulation (default).
DopplerTracking DOPPLER_TRACKING_IDLE_STEP = 1
Simulate Doppler effect by tracking positions of objects that are changed in _process
. Changes in the relative velocity of this camera compared to those objects affect how audio is perceived (changing the audio's AudioStreamPlayer3D.pitch_scale).
DopplerTracking DOPPLER_TRACKING_PHYSICS_STEP = 2
Simulate Doppler effect by tracking positions of objects that are changed in _physics_process
. Changes in the relative velocity of this camera compared to those objects affect how audio is perceived (changing the audio's AudioStreamPlayer3D.pitch_scale).
Property Descriptions¶
CameraAttributes attributes
void set_attributes ( CameraAttributes value )
CameraAttributes get_attributes ( )
The CameraAttributes to use for this camera.
int cull_mask = 1048575
The culling mask that describes which 3D render layers are rendered by this camera.
bool current = false
If true
, the ancestor Viewport is currently using this camera.
If multiple cameras are in the scene, one will always be made current. For example, if two Camera3D nodes are present in the scene and only one is current, setting one camera's current to false
will cause the other camera to be made current.
DopplerTracking doppler_tracking = 0
void set_doppler_tracking ( DopplerTracking value )
DopplerTracking get_doppler_tracking ( )
If not DOPPLER_TRACKING_DISABLED, this camera will simulate the Doppler effect for objects changed in particular _process
methods. See DopplerTracking for possible values.
Environment environment
void set_environment ( Environment value )
Environment get_environment ( )
The Environment to use for this camera.
float far = 4000.0
The distance to the far culling boundary for this camera relative to its local Z axis.
float fov = 75.0
The camera's field of view angle (in degrees). Only applicable in perspective mode. Since keep_aspect locks one axis, fov
sets the other axis' field of view angle.
For reference, the default vertical field of view value (75.0
) is equivalent to a horizontal FOV of:
~91.31 degrees in a 4:3 viewport
~101.67 degrees in a 16:10 viewport
~107.51 degrees in a 16:9 viewport
~121.63 degrees in a 21:9 viewport
Vector2 frustum_offset = Vector2(0, 0)
The camera's frustum offset. This can be changed from the default to create "tilted frustum" effects such as Y-shearing.
Note: Only effective if projection is PROJECTION_FRUSTUM.
float h_offset = 0.0
The horizontal (X) offset of the camera viewport.
KeepAspect keep_aspect = 1
void set_keep_aspect_mode ( KeepAspect value )
KeepAspect get_keep_aspect_mode ( )
The axis to lock during fov/size adjustments. Can be either KEEP_WIDTH or KEEP_HEIGHT.
float near = 0.05
The distance to the near culling boundary for this camera relative to its local Z axis.
ProjectionType projection = 0
void set_projection ( ProjectionType value )
ProjectionType get_projection ( )
The camera's projection mode. In PROJECTION_PERSPECTIVE mode, objects' Z distance from the camera's local space scales their perceived size.
float size = 1.0
The camera's size in meters measured as the diameter of the width or height, depending on keep_aspect. Only applicable in orthogonal and frustum modes.
float v_offset = 0.0
The vertical (Y) offset of the camera viewport.
Method Descriptions¶
void clear_current ( bool enable_next=true )
If this is the current camera, remove it from being current. If enable_next
is true
, request to make the next camera current, if any.
RID get_camera_rid ( ) const
Returns the camera's RID from the RenderingServer.
Transform3D get_camera_transform ( ) const
Returns the transform of the camera plus the vertical (v_offset) and horizontal (h_offset) offsets; and any other adjustments made to the position and orientation of the camera by subclassed cameras such as XRCamera3D.
bool get_cull_mask_value ( int layer_number ) const
Returns whether or not the specified layer of the cull_mask is enabled, given a layer_number
between 1 and 20.
Plane[] get_frustum ( ) const
Returns the camera's frustum planes in world space units as an array of Planes in the following order: near, far, left, top, right, bottom. Not to be confused with frustum_offset.
RID get_pyramid_shape_rid ( )
Returns the RID of a pyramid shape encompassing the camera's view frustum, ignoring the camera's near plane. The tip of the pyramid represents the position of the camera.
bool is_position_behind ( Vector3 world_point ) const
Returns true
if the given position is behind the camera (the blue part of the linked diagram). See this diagram for an overview of position query methods.
Note: A position which returns false
may still be outside the camera's field of view.
bool is_position_in_frustum ( Vector3 world_point ) const
Returns true
if the given position is inside the camera's frustum (the green part of the linked diagram). See this diagram for an overview of position query methods.
void make_current ( )
Makes this camera the current camera for the Viewport
