[3D] Preview vs Face Mesh

Display 3D objects, scenes, and animations on your iPhone and iPad. The document-based user interface for opening documents is beautiful and easy to use. You can access files that are stored locally, on iCloud Drive, and other cloud storage services. Key features: • Display simple or complex 3D objects and scenes on your iOS device • View your content with up to 120 FPS on devices with ProMotion display (otherwise in 60 FPS) • Choose your point of view by using the free moving camera with touch controls • Display the scene graph of your scene to see what objects are present (grouped by their categories and parent-child relationships) • Choose from various debug settings to help trouble shoot your scene (e.g., display wireframes, bones, cameras) • Color accurate presentation of your content with support of HDR on devices with wide color displays • Support for vertex and fragment shaders written in the Metal Shading Language • Extremely fast as the app is based on Metal 2 and uses heavily multi-threading for various tasks • Native iOS app, which is entirely written in Swift 5 Supported document types: • SceneKit (.scn) • Alembic (.abc) • Universal Scene Description (.usd, .usda, .usdc) • Universal Scene Description Mobile (.usdz) • Polygon (.ply) • Wavefront Object (.obj) • Standard Tessellation Language (.stl)

Face Mesh app is for iOS developers who need to visually learn the vertex indices for the ARFaceGeometry face mesh provided by Apple Developer. These vertex indices are very important for working in ARKit and especially for developing FaceTracking apps. You will be able to see the actual location of each vertex in the 3D face mesh grid. Each vertex is labeled with its index as it exists in ARFaceGeometry.vertices() • Tap on individual vertices to select/deselect. • Use All, None & Invert options to easily build complex selections. • Easily select face geometry outline and individual eyes. • Export your selections as an array of indices with one tap. How to move around the face mesh? - Pinch to zoom in/out - Pan with one finger to rotate - Pan with two fingers to move - Rotate with two fingers to rotate on the z-axis
