RAYS - 3D Path Tracer

RAYS is a real path tracer for iPhone and iPad: the same kind of light simulation used by film and product-visualization renderers, running on your device's hardware ray tracing. Hit Render, and watch a photoreal image come together in seconds. IMPORT • Open USDZ, USD, glTF, GLB and OBJ models, from Files, Mail, Messages or AirDrop ("Open in RAYS"). • Materials, textures, variants and lights come in with the model; your original file is never changed. • Add several models to one scene; move, turn and scale them with an on-screen gizmo. LIGHT • Three studio HDRIs light your model with real image-based light. Turn them, set their exposure, or show them behind the model. • Add sun, bulb, spot and area lights. • Shadow catcher: an invisible floor that catches soft shadows and reflections. • Ground projection lays the HDRI's floor under your model. • Backdrop colors, with Bounce light: the set color lights your model back, like a colored studio cyc. RENDER • Progressive path tracing: soft shadows, reflections, glass and bounce light, refining with every sample. • Physically based materials: metal, glossy and rough surfaces, clear coat, clear and frosted glass. • A denoiser for clean images faster, and depth of field with real camera settings and Tap to Focus. • Render at screen size or larger (2× and 3×), or at 720p, 1080p, 4K or 4:3. • Save renders to Photos as PNG or HDR photos, plus EXR for compositing. COMPOSITE • Put your model into your own photo: pick a picture from Photos or Files, drag, pinch and twist it into place, and lock it. • The shadow catcher sets your model on the photo's floor; the HDRI lights it to match. • Depth of field blurs the picture along with the scene, and film grain (amount, size, color) ties render and photo together. • Camera Roll tilts the camera to match a photo that wasn't shot level. PREVIEW • A fast real-time Preview for framing and arranging, with Preview Effects: ambient occlusion, curvature, depth of field, bloom, tone mapping (Neutral, AgX, ACES), color balance, vignette, grain and more. SCENES • Save your scene, with every move, light, camera and material edit, as one file that opens in Quick Look and other USD apps. • Start on iPhone, AirDrop the scene to your iPad, and pick up right where you left off: the models, lights, cameras and HDRI all travel in the one file. • Saved cameras, including a Default camera to get back to the opening view. • Sample scenes to start from: Sketchbot, Material Spheres and two classic Cornell boxes. Designed first for iPhone Duo, folded or open, and at home on iPhone and iPad. REQUIREMENTS Rendering is fastest with hardware ray tracing: iPhone 15 Pro, iPhone 16 or later; iPad Pro (M4 or later), iPad Air (M3 or later), iPad mini (A17 Pro or later). Older devices render more slowly.
