"Finger3D" turns your device into a three-dimensional modeler, the smallest and portable existing 3D modeler. With "Finger3D" you can create any shape/object/3D model, modeling the shapes with the fingers of your hands. To create Your 3D MODEL, You will have the 3D geometric primitives (spheres, cylinders, cones, cubes, planes, surfaces, discs, curves, etc...) typically used in the commercial 3D modelers for the PC or MAC. You can manage the parameters for lighting (eg. lamp position), material (eg. material’s color, textures), the object transparency, etc... You can navigate the 3D WORLD using the fingers of your hands; you can use the 3D view, the top view (Y UP), right view (X UP), frontal view (Z UP). You can explore the 3D WORLD using the first person view (NAVIGATION MODE). You can model the objects in the 3D WORLD, scale, rotate, move the vertices dragging Your fingers on the screen or use the blue 3D ball pointer to select/move objects/vertices/faces. You can quickly locate the pointer in the 3D space by writing the X, Y, Z coordinates, using the “pointer move” buttons (along the axes X, Y, Z). The size of the objects can be defined, during insertion, with the "POINTER RADIUS" control or using the scale feature (in editing mode). With "POINTER RADIUS" you can select one or more vertices/objects/faces; increasing the size of the "POINTER RADIUS" You can select multiple components. Instruments for the 3D modeling: 0) CHARACTER MODELING using BACKGROUND IMAGES 1) MODEL with fingers: move the touched vertices by dragging Your finger on the screen 2) SUBDIVIDE: divide one or more faces into 4 or more faces for each face 3) EXTRUDE: extrusion perpendicular or oblique for faces or vertices (extrusion direction: from the center of the selected face to the center of the 3D pointer or along the three axes X,Y,Z) 4) SMOOTH: useful for the creation of mountains 5) VLINK: move the vertices in the center of the 3D pointer (useful to create arrows, beaks of animals, aircraft, wings, etc...) 6) COPY/PASTE 7) COPY MIRROR (respect the chosen axis or along it) 8) ERASE VERTICES / FACES 9) FACES EDITING / VERTICES EDITING 10) REVOLVE 11) REVOLVE "SPIN" 12) REVOLVE "BASE FACE" (to create people with one click) 13) MOVE 14) 3D and 2D views 15) SMOOTH SHADING, FLAT SHADING, WIREFRAME 16) GROUP/UNGROUP 17) UNDO/REDO etc… The model may be manually or automatically saved for later use, exported to OBJ+MTL format and then be sent via e-mail or loaded in the common 3D modelers for the PC o MAC (ex. Maya 3D, Blender, etc...). RENDERING: the generated JPG/PNG image according to the policy "render what you see" will be saved in the device’s photo album (can be sent by e-mail if necessary). PERSPECTIVE and ORTHOGRAPHIC projections. The “Projects Archive” allows storing, management, loading and merging projects. You can see the model in all its parts, activating the animation. The ability to apply textures photographed (with the camera of the device) to the 3D model will give you the feeling of working with real 3D models. The 3D graphics has been fully implemented using OpenGL, with the graphic acceleration used for the PC games. Useful for all types of use: for Engineers (computer, mechanical, electrical, chemical), Architects (eg. design and rendering), Chemicals (ex. design of molecules), Astronauts, Astronomers, Designers, Filmmakers, Gamers, Biologists, Interior Designers, etc... Finger3D has been designed to work well together to FingerCAD: You can model in a 3D WORLD the design started with a 2D CAD, apply textures to the 3D model, explore the CAD design using the first person view (3D CAD VIRTUAL REALITY NAVIGATION feature), create realistic images using the rendering procedure.

AI ON YOUR PHONE. POWERED BY YOUR DEVICES. Run private AI directly on your phone. Need more power? Connect your own computer and let it handle the heavy AI work while you keep using microAI from your phone. No sign-up. No cloud AI account required. Ask questions. Talk instead of type. Show AI a photo. Read a file. Work on a project. Save something for later. microAI brings local AI, your devices, and your private context together in one workspace. YOUR PHONE. YOUR COMPUTER. YOUR AI. Your phone can run compatible local AI models on its own. When you need more power, connect your own computer. Scan a QR code and your approved Mac or browser can run the model while you continue using microAI from your phone. That means you can move heavier AI work off your phone—reducing the load, heat, and battery use caused by demanding on-device inference. Use your phone when that is enough. Use your computer when you want more power. You choose where your AI runs. NO SIGN-UP. NO CLOUD AI REQUIRED. Local AI should not require another account. microAI can run compatible models directly on your devices without requiring a cloud AI account. Your computer can also become your own AI compute node. Open the microAI website on your computer, load a compatible local model, scan the QR code, and connect. No separate website account is required. DIFFERENT AI FOR DIFFERENT JOBS Not every task needs the same AI. microAI includes task-focused AI helpers: • Private Chat — Ask, write, plan, brainstorm, or talk. • Image Chat — Ask questions about photos and screenshots. • Voice Chat — Talk instead of typing. • Review Writer — Turn your experience into a clear review. • Photo Tagger — Create titles, descriptions, and keywords for photos. Choose which compatible model powers each job. Use a small model for quick everyday tasks, a vision model for images, or a stronger model running on your computer when you need more capability. TALK. SEE. READ. AI should work with more than a text box. Talk naturally with Voice Chat. Add a photo or screenshot and ask questions about what you see. Add a supported PDF, TXT, or Markdown file and ask questions about its contents. Use microAI for writing, research, documents, photos, ideas, and everyday questions. COME BACK WITHOUT STARTING OVER Your useful context should not disappear into old chats. Create Projects to keep related conversations, files, instructions, and context together. Save quick thoughts in Journal. microAI can remember useful context and bring it back when relevant. Memory Map gives you a visual way to explore your conversations, projects, journals, models, and memories. LOCAL AI WITHOUT THE USUAL SETUP You should not need to be an AI engineer to start using local AI. Find a compatible model, download it, and start. microAI keeps model discovery, downloads, switching, and resource management in one place. Advanced users can also import compatible GGUF models. Actual performance depends on your device, model, and connection. YOUR AI. YOUR DEVICES. YOUR DATA. When AI runs on your phone, compatible models process requests directly on your device. When you connect your own computer, the model runs on the computer you approve while you continue using microAI from your phone. Your model files stay on the device running them. You decide when a remote compute node is connected and used. Internet access may still be required for model discovery and downloads, purchases, ratings, app services, and certain system features. RUN AI YOUR WAY. On your phone when you want portability. On your computer when you want more power. No sign-up. No cloud AI account required. Your AI. Your devices. Your choice.
