Finger3D HD turns your device into a three-dimensional modeler, the smallest and portable existing 3D modeler.
With "Finger3D HD" 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.

* .OBJ Projects Archive added:
1) store all your OBJ 3D models into Finger3D "Documents" folder using "iTunes File Sharing"
2) open "OBJ Projects Archive", select an OBJ model, import and merge it with current project (You can merge two or more OBJ projects with current project workspace)
---

---
* DROPBOX / iDisk integration:
1) READ remotely stored OBJ files:
- read, modify, save (into "Finger3D project archive") obj files stored on DROPBOX or iDisk server: You can open obj file with Finger3D directly from the DROPBOX or iDisk client for iTouch/iPhone/iPad (FREE) clicking on the "open in" button in the DROPBOX or iDisk client and choose Finger3D --> the chosen obj file will be opened automatically by Finger3D (you can also merge more than one obj files into the current workspace importing them one after the other from DROPBOX or iDisk - Finger3D will work in background). It works like the "Finger3D OBJ Archive" but the archive is saved into the DROPBOX or iDisk server
2) UPLOAD modified OBJ:
You can now upload obj files (read from Finger3D archive, DROPBOX or iDisk servers, E-MAIL, WEB LINK and modified with Finger3D itself) to DROPBOX or iDisk servers:
load obj file created by your friend, modify it, save it where you want, copy modified obj file into a DROPBOX or iDisk shared folder and your friend will have your version of obj file (all can be done using an internet connection).
---
* E-MAIL integration:
- read, modify, save (into "Finger3D project archive") obj files from email attachments
---
* WEB LINK integration:
- read, modify, save (into "Finger3D project archive") obj files directly from an internet link

- divide an object into two or more objects and model each one new object independently (for example divide a sphere into two semi-sphere and rotate/scale only one semi-sphere)
- divide an object with many vertexes into more objects with less vertexes and model each one independently, in a more simple way
- etc…
for example with GROUP new feature user can:
- link two or more objects into only one more complex object and apply to the new complex object the same color or the same transformations
