You can use AnchorEntity(.image(...)) in SwiftUI almost the same way as you used it in UIKit. At first click Assets.xcassets in Project Navigator pane and create AR Resources folder. Drag your image there. Setup its physical size in Inspector. Then copy/paste the code:

At the low level, RealityKit is only responsible for rendering virtual objects and overlaying them on top of the camera frame. If you want to illuminate the real scene, you need to post-process the camera frame.

Here are some tutorials on how to do post-processing: Tutorial1⃣️ Tutorial2⃣️

If all you need is an effect like This , then all you need to do is add a CGImage-based post-processing effect for the virtual object (lights).

More specifically, add a bloom filter to the rendered image(You can also simulate bloom filters with Gaussian blur).

In this way, the code is all around UIImage and CGImage, so it's pretty simple😎

If you want to be more realistic, consider using the depth map provided by LiDAR to calculate which areas can be illuminated for a more detailed brightness.

Or If you're a true explorer, you can use Metal to create a real world Digital Twin point cloud in real time to simulate occlusion of light.

Try this. Take into consideration, a tint color is multiplied by an image – so, if tint's RGBA = [1,1,1,1], a result of multiplication will be an image itself (without tinting)...

AR Core requires some specific hardware to work. You can check the list of supported devices here. No amount of side loading will help because this is a hardware requirement issue. Moreover AR Core is under active development even if you somehow install a version that might work that version will soon be deprecated and you will start getting the popup saying you need to update.

Kindly use a device that is part of supported list or an Emulator that supports this. IMHO it is best to develop using a device that has support from AR Core team.

When you perform a hit-test search, SceneKit looks for SCNGeometry objects along the ray you specify. For each intersection between the ray and a geometry, SceneKit creates a hit-test result to provide information about both the SCNNode object containing the geometry and the location of the intersection on the geometry’s surface.

The problem in your case is that when you modify the buffer’s contents (MTLBuffer) at render time, SceneKit does not know about it, and therefore cannot update SCNGeometry object which is used for performing hit-test.

So the only way I can see to solve this issue is to recreate your SCNGeometry object.

Uploading a .reality model from web works fine. You can easily check this in Xcode Simulator:

Intrinsics camera matrix converts between the 2D camera plane and 3D world coordinate space. Here's a decomposition of an intrinsic matrix, where:

• fx and fy is a Focal Length in pixels
• xO and yO is a Principal Point Offset in pixels
• s is an Axis Skew

According to Apple Documentation:

The values fx and fy are the pixel focal length, and are identical for square pixels. The values ox and oy are the offsets of the principal point from the top-left corner of the image frame. All values are expressed in pixels.

So you let's examine what your data is:

Your code works fine (a position was a problem):

It occurs because ARMeshAnchors constantly update their data as ARKit refines its understanding of the real world. All ARMeshAnchors are dynamic anchors. However their mesh's subsequent changes are not intended to reflect in real time.

If you want to duplicate your ARMeshAnchors collection use the following code:
