Exact 3D Extract

*****TURN YOUR ANDROID DEVICE INTO A 3D SCANNER*****

Use your tablet's camera to create and texture 3D models of everyday objects. This App works by finding the shape of an object and wrapping pictures around it (four pictures are used for rectangular prisms and twenty-four pictures are used for cylindrical objects). Once you have created a model you can then export the model into a variety of formats to be opened in your favorite 3D-modeling software, 3D-animation software, imported into a video game, or even printed straight off a 3D printer. Model texturing can also be edited in app.

*****DEMONSTRATE CALCULUS WITH OBJECTS OF ROTATION*****

Draw any equation on an un-lined piece of paper or on a blackboard, and this program will create the object of rotation produced by performing the disk method on the equation

*********************************

NOTE: requires a rear facing camera

NOTE: designed only for high-end tablets, may or may not work with lower end devices

NOTE: .STL file format does not support texture

NOTE: .OBJ and .STL only current supported file types. More file types to come

NOTE: For the best results choose a background color that contrasts with the color of the object you plan on modeling. For example, a black object on a dark blue background will not work as the app will have difficulty finding the objects edges. A better option would be a light color or white.

**DIRECTIONS**

This App will create and texture a model of a simple object.

The program is preset to work with a turntable that turns once every 20 seconds, but the front screen also has an option to set the rotation time for your turntable.

****Creating a Textured Model****

1. Place your object in the middle of a rotating turntable.

2. Launch the App and select options.

2A. Select Object Color vs Background Color. This option allows the App to correctly find the edges of your object.

NOTE: For the best results choose a background color that contrasts with the color of the object you plan on modeling. For example, a black object on a dark blue background will not work as the app will have difficulty finding the objects edges. A better option would be a light color or white.

2B. Select "With Texture" from the menu.

2C. If your turntable has a different rotation rate than the default (1 rotation per 20 sec) set rotation time from menu.

NOTE: This only has to be done once.

2D. Select Shape type from Menu. Cylinder will work for any object of rotation. Tap the text to continue.

3. Follow instructions on App and place device in frame.

3A. With the device in the frame center the target object where you can see both the top edge and the bottom edge of the object in your view.

3B. For a not overly shiny object we found it useful to turn on the device's flashlight.

4. Review your model on the model view screen.

5. From the Menu items select an export method and export as type .obj (Obj files allow for textures).

NOTE: Exporting a model as an .STL will not allow for Textures.

*****Creating a Simple Model*****

1. Place the object on a table in front of a solid colored background.

2. Launch the App and select options

2A. Select object color vs Background color. This option allows the App to correctly find the edges of your object.

NOTE: For the best results choose a background color that contrasts with the color of the object you plan on

modeling. For example, a black object on a dark blue background will not work as the app will have difficulty

finding the objects edges. A better option would be a light color or white.

2B. Select "Without Texture" from the menu.

2C. Select Shape type from Menu. Cylinder will work for any object of rotation. Tap the text to continue.

3. Take the required number of pictures

4. From the menu select an export method.
