Class
ARCamera
Topics
Handling Tracking Status
var trackingThe general quality of position tracking available when the camera captured a frame.
enum ARCameraValues for position tracking quality, with possible causes when tracking quality is limited.
Examining Camera Geometry
var transform: matrix_float4x4The position and orientation of the camera in world coordinate space.
var eulerThe orientation of the camera, expressed as roll, pitch, and yaw values.
Examining Imaging Parameters
var imageThe width and height, in pixels, of the captured camera image.
var intrinsics: matrix_float3x3A matrix that converts between the 2D camera plane and 3D world coordinate space.
Applying Camera Geometry
var projectionA transform matrix appropriate for rendering 3D content to match the image captured by the camera.
func projectionReturns a transform matrix appropriate for rendering 3D content to match the image captured by the camera, using the specified parameters.
func viewReturns a transform matrix for converting from world space to camera space.
func projectReturns the projection of a point from the 3D world space detected by ARKit into the 2D space of a view rendering the scene.
