It's easy to make a Facetopo. You only need wifi and about 10 minutes.
Using your iPad (preferred - larger screen size is easier to see) or iPhone, go the iTunes App Store and search for “Facetopo” and install

Get ready for your close-up. If you have long hair or bangs put them back so both of your ears and eyebrows are completely visible. Make sure your device audio is on and not on mute.
Check yourself out. Put your device flat on a wall to eliminate extra angles. Are there shadows on your face? Move to a different wall. Adjust your distance from the camera so your face fits inside the outline. Practice turning to profile - 90 degrees so you can find a visual spot. If straight ahead is noon, look to 3 o'clock for the profile pic.
Capture your Selfies. When you're ready tap START the app will automatically take your front selfie, and a voice will guide you and tell you when to turn to profile, and the app will take your side selfie. No need to peek at the camera, keep your gaze even and straight ahead.
Check your Selfies. Review the checklists for both front and side pics. You can RETAKE them as many times as you like. When you tap ACCEPT we’ll generate your face-map
Improve the accuracy of your face-map in front view, by dragging the dots if they're not perfect
Then you’ll map your side photo by placing some dots
Then watch the GIZMO autoalign to your side pic to bring it into 3D space. You can then manually adjust the GIZMO if needed
Set the remaining dots in Side view
Tap SEND DATA and you’ll see your face in 3D. Share it!
