ImagePresentationComponent

A component that supports general image presentation.

Declaration

struct ImagePresentationComponent

Overview

ImagePresentationComponent supports the presentation of three different kinds of images in RealityKit:

  • A traditional 2D image.

  • A spatial photo, which is a stereoscopic photo with additional spatial metadata, as captured on iPhone 15 Pro or later and Apple Vision Pro.

  • A spatial scene, which is a 3D image generated from an existing 2D image or photo.

To present a 2D image or a spatial photo, create a new ImagePresentationComponent from a local file URL for the existing image, or from an existing CGImageSource.

To generate and present a spatial scene from an existing image, create a ImagePresentationComponent.Spatial3DImage from the image; call the generate() method on your new spatial 3D image; then create a new ImagePresentationComponent with init(spatial3DImage:).

Viewing modes

By default, an ImagePresentationComponent presents its image in a mono viewing mode, regardless of what kind of image you create it with.

To request a different viewing mode, set the component’s desiredViewingMode property, and add the component to an entity with the updated value.

To discover which viewing modes a component’s image supports, query the component’s availableViewingModes property. The availableViewingModes set always contains mono as an option.

When you create this component with a valid spatial photo, the set of available viewing modes also contains spatialStereo and spatialStereoImmersive.

If you created the component with a ImagePresentationComponent.Spatial3DImage, and have called the generate() method to generate it, the set of available viewing modes will also contain spatial3D and spatial3DImmersive.
