struct ProjectiveTransformCameraComponent

A component that defines a virtual camera with a custom projection matrix. ## Overview Each scene requires a camera, which defines the viewpoint from which RealityKit renders the scene. The projective transform camera renders the entities in the scene based on a custom user defined matrix. For this component, define a matrix that is either of symmetric perspective or orthographic projection. Define symmetric perspective matrices using reverse depth i.e., a matrix with near and far reversed. To create a projective transform camera, add this component to an entity. ```swift // Create a projective transform camera component with a custom matrix. let projectiveTransform = ProjectiveTransform3DFloat( fovY: Angle2DFloat(degrees: 90.0), aspectRatio: 0.6, nearZ: 0.01, farZ: 1000.0, reverseZ: true) var projectiveCameraComponent = ProjectiveTransformCameraComponent(projectionMatrix: projectiveTransform.matrix) // Create an entity with the camera component. let cameraEntity = Entity(components: projectiveCameraComponent) // Set the entity's position and orientation to look at the subject (the origin in this case). let cameraPosition: SIMD3<Float> = [0, 1, 3] let target: SIMD3<Float> = .zero cameraEntity.look(at: target, from: cameraPosition, relativeTo: nil) // Add the camera entity to your scene. content.add(cameraEntity) ```
