Valence 3D is a powerful, beautiful, minimal, and easy-to-use 3D Polygon & SubD modeling app for iPad & iPhone. No matter whether you're learning 3D modeling for the first time or a professional working in design, construction, gaming, web dev, digital fabrication, architecture, or spatial computing, Valence 3D has what you need to get started! CREATE, IMPORT, EDIT & EXPORT 3D MODELS • 25 primitive shapes are built-in & ready to help you start modeling: plane, box, sphere, squircle, rounded box, arc, circle, cylinder, tube, cone, capsule, torus, icosphere, pipe, revolve, helix, voronoi, text, super shape, noise surfaces, torus knot, faceted gem & tube. • Import existing models, reference images, lidar scans and room plans • Imports: OBJ, STL, USD, USDZ • Exports: PNG, SVG, OBJ, STL, USD, USDZ, GLTF, GLB • Knife tool to create complex and detailed geometry • Move, Rotate, & Scale gizmos make it easy to transform nodes, faces, edges & vertices • Powerful modeling gizmos for extruding, insetting, beveling, poking, creasing & cutting • Multiple selection & automatic loop selection help accelerate your modeling • Tap on one of the gizmo handles to bring up an input field for precise transformations & mesh operations • Robust snapping & alignment commands • Selection operations: grow, shrink, select shell & deselect • Mesh operations: duplicate, instance, set / center pivot, trim by plane, boolean, apply transform & subdivide • Face operations: separate, combine, bridge, extract, poke, collapse, delete, dissolve, harden & soften • Edge operations: extrude, insert vertex, collapse, dissolve, bridge, harden & soften • Vertex operations: insert edge, dissolve, delete & merge • Non-destructive & configurable mesh modifiers: mirror & subdivision • Apply complex transformations using different gizmo pivot points & orientations EASILY NAVIGATE & STAY IN FLOW WHILE DESIGNING • Carefully crafted & fully optimized for iPhone & iPad • Designed to minimize cognitive overload by only showing tools & commands that are contextually relevant • Easily navigate to any part of your model by dragging and pinching: two finger pinch to zoom and roll, and one finger drag to rotate • Pop into the standard orthographic views by tapping one of the handles of the orientation gizmo • Use two & three finger tap gestures to undo & redo • Select components by dragging or using the rectangular selection mode • Your work is saved automatically every two minutes and every time you go back to the gallery • Get an overview of your scene’s structure from the Outliner • Long press on a node in the Outliner to easily rename, duplicate, instance, delete, parent & reorder any object in your scene • Precisely adjust any node’s position, rotation & scale with the Inspector • Adjust material properties, display & modifier options with the Inspector STAY ORGANIZED ACROSS ALL YOUR DEVICES • Preview, share, duplicate, delete & rename your models from the gallery • iCloud syncing keeps all your models up to date, private & accessible across all your devices PREVIEW, MEASURE, & RENDER YOUR CREATIONS • 6 powerful rendering modes: Matcap, Modeling, Wireframe, Physically Based, X-Ray & Path Traced • Export renders in any aspect ratio & scale • Preview your model in AR in two taps • Export your scene as a USDZ & be confident it’ll look consistent on all Apple devices • Tweak your model’s material & see changes in real-time • Tweak-able scene settings: camera field of view, background type, blurriness, intensity & rotation • Get model measurements in one click • Add persistent dimensions between any two surfaces in your scene PURCHASE & COMPATIBILITY • One time purchase unlocks both iPhone & iPad versions • Apple Pencil supported on select iPads • 120 FPS supported on devices with ProMotion displays • Path Tracing is supported on iPads with M series chips & iPhones with A15 Bionic & later • Lidar Scan & Room Plan is supported on devices with a lidar sensor

About

specimen · renato.design

Read full description

specimen is a 3D scanning app for iPhone that treats the captured object as a specimen — worth describing, worth situating, worth demystifying. You point the phone at a thing. You walk around it. You flip it over. You capture the bottom. The app produces a mesh you can open in Rhino, Blender, or any 3D software. Witness describes what was captured in clinical language. A registrar's voice. Surface reads as glazed ceramic. Bottom not captured. Approximately fourteen centimeters across. Afterwords is six voices from the dead. Sōetsu Yanagi speaks on the beauty of humble objects. Walter Benjamin speaks on what scanning itself is — what aura means when an object is captured. D'Arcy Thompson speaks on the forces that made the form. Roland Barthes speaks on the detail that pierces the viewer. George Kubler speaks on where this object sits in its class. Vilém Flusser speaks on the gesture of capture. Concordance names the mechanism, not the marketing term. Light detection and ranging. Infrared pulses. Time of flight. Structured light. Photogrammetry. Triangulation. Exports in millimeters, Z-up — the Rhino-default design-studio convention. Switchable to inches for the truly stubborn or architects among you. Share a capture package as a .zip and AirDrop it to a Mac running the free specimen Companion for full-detail reconstruction Apple only exposes on macOS. Requirements: iPhone with LiDAR (iPhone 12 Pro or later Pro / Pro Max). Apple Intelligence–capable device if you want the voices to speak on-device; the app falls back cleanly otherwise. No cloud. No account. No credits. No subscription. Built for students and makers as a tool for contemplative work. specimen is part of renato.design, a creative research practice authored through Iterative LLM Co-Authorship — a collaboration between Phil Renato and Claude (Anthropic). Released as a research artifact, not commercial software. See the disclaimer in Settings → About for details.
