Detailed Description

An ARCamera is a subclass of ARNode that represents the root of the scenegraph. It is attached to an ARViewPort and controls the projection.

Method Documentation

+ (ARCamera *) defaultCamera

Reference to a default static camera. Will be created if it hasn't already.

Example of use:

ARCamera *camera = [ARCamera defaultCamera];

Property Documentation

- (CGPoint) fov

readwritenonatomicassign

The cameras horizontal and verticle field of view. The x represents the horizontal fov and the y represents the vertical fov.

- (CGPoint) frustumPlaneDistance

readwritenonatomicassign

The far plane distance of the camera frustum.

- (CGPoint) principlePoint

readwritenonatomicassign

The principle point of the camera. This is where the optical axis intersects the image plane.

- (ARMatrix4*) projectionMatrix

readwritenonatomicassign

The projection matrix representing the camera intrinsics. A computer monitor is a 2D surface. A 3D scene rendered must therefore be projected onto the computer screen as a 2D image. The projection matrix is used for this projection transformation. First, it transforms all vertex data from eye space to world space. The resulting coordinates are then transformed from camera space to screen space.

- (ARViewPort*) viewPort

readwritenonatomicweak

The viewport this camera is attached to, or nil if detached.
