##What is #GetReal?

Creators and Developers often like to tinker and make things. For software designers, testing out a new idea is as easy as the push of a keyboard button. But for hardware and mechanical-oriented enthusiasts, experimentation is time consuming and difficult, requiring either a drawn out, repetitive fabrication of a singular object or a pain-staking analysis on ensuring perfection for a first-pass construction.

Using the power of augmented reality, #GetReal levels the playing field. Now you can load up an stl file of a CAD, put on some Virtual Reality Goggles, and see what your CAD would look like in 3D space, all before you even had to touch a single piece of material. Users can have access to the same kind of quick testing that software engineers do, simply making some tweaks in the CAD, re-uploading, and seeing how the changes appear in the real world. #GetReal allows for rapid prototyping and efficient iterations, streamlining the process of development for aspiring mechanical and electrical engineers.

##Getting Started

Using #GetReal requires some extra hardware in addition to software dependencies in order to run the code. For external hardware, you will need:

• Google Cardboard (or some other VR headset)
• High Performance Webcam
• A smartphone (ios or android)
• Splashtop Streamer (from app store)
• Four blue post-it notes in a square, with one blue post-it colored black in the center.

Once you have all your hardware, you will also need to download Python and the following python packages:

• Pip $sudo install pip
• OpenCV $sudo pip install opencv
• OpenGL (download from website http://pyopengl.sourceforge.net/documentation/installation.html)
• STL $pip install numpy-stl
• Numpy $pip install numpy
• PIL sudo pip install pil
• imutils sudo pip install imutils

##Usage

After you have your environment configured, take the CAD file you want to view and save it as a binary .stl. Copy it into the folder that contains our Github repository. Once you have everything set up, first, set up the computer to phone connection. Run Splashtop on your computer and phone, and pair them together. Once you see your computer screen on your phone, run GetReal.py, and insert the name of the .stl. You are all ready to view the CAD model! From your Google Cardboard, you should see your CAD model augmented into 3D space where your post it notes are. You can press space to rotate the CAD, M to decrease size and K to increase size. You can even press the number keys to change the color of the stl! Press r to reinput an stl file. (Make sure GetReal2 is selected when making keystrokes.) Try walking around it and viewing it from different angles. You should see the CAD model in its entirety, as if it was right in front of you. Have fun prototyping!

##Acknowledgements

The team would like to thank Software Design Teachers Paul Ruvolo, Ben Hill, and Oliver Steele for their guidance and expertise. We would also like to thank the NINJAs Sophia Li, Patrick Huston, Rocco Diverdi, and Lucy Wilcox for their assistance in bugs and roadblocks along the way. Finally, a big thanks from the team to its individuals for sticking it out and accomplishing such an ambitious project in a 6 week time frame.
