Helena High students' idea for 3D-modeling app in national contest

A mobile app conjured by a group of Helena High students might turn heads in Silicon Valley.

It would also turn everyday objects into digital 3D models, which could then become the stuff of video games or 3D printers.

Instead of taking photos with your phone, imagine using it to help create true-to-life replicas.

The idea has proven to be a winning one for the six computer science students. The team recently topped state and regional contests for the Verizon Innovative App Challenge and will soon learn if they’re the best in the nation.

They’ve already bagged $5,000 for Helena High by winning the West region, which includes every state west of the Dakotas. If they win at the national level, the team will bring home another $15,000 for the school and tablet computers for themselves.

The competition asks middle and high school students to develop an original concept for a mobile app that fills a need in their school or community.

Helena High, advised by teacher Buffy Smith, beat out more than 20 submissions around the state. Laurel Middle School won the state competition among middle schools with a “Speak 360” app that would assist students who are speech or hearing impaired.

Teams submitted detailed descriptions of their idea and produced a video to pitch it. At the national level, the pitch also included a judging by Verizon executives and MIT professors via videoconference.

No programming is required, but teams must bring their skills to bear to demonstrate that the app isn’t entirely out of this world, according to junior Jake Pennington.

“You had to show how it could be plausible,” he said.

If their “Exact 3D Extract” idea seems farfetched, think again, the students said.

The app would work like this: The user would rotate the phone 360 degrees around an object, while the app creates a digital rendering.

That rendering could then be edited with software like AutoCAD or Google SketchUp, senior Bridger Howell said, or sent to a 3D printer for physical reproduction.

“All it does is make the model,” Howell said.

While the team said the app would be simple and user-friendly, the mathematics behind it is quite complex.

Pennington mused that their app could encourage development of hardware accessories, such as a railing to stabilize the phone or a turntable to spin the object. Both would make the models more accurate, they said.

One factor they’ve had to consider is if mobile devices would have enough processing speed to handle the modeling function.

“Theoretically,” Howell said, “it could be something that could take a long time.”

However, the students noted that the pace of tech development suggests that what is unfeasible one day is within reach the next.

Today’s mobile apps haven’t come close to reaching their full potential, senior Sage Smith said.

Pennington said the 3D extract idea was conceived with a future in mind in which 3D printers become commonplace in average households.

“It’s going to be big. I could see it replacing modern manufacturing,” Smith added.

If that’s the case, Smith said he’s pretty sure their concept will become reality somewhere, in some form.

“The judges seemed really impressed with our idea,” he said.

This story has been updated to include the name of adviser Buffy Smith.

    While I am happy for these students, I am surprised they have made it this far. There at least three apps that do this already, 123d Catch from AutoDesk, Trimentional, and another from Switzerland.




Civil Dialogue

We provide this community forum for readers to exchange ideas and opinions on the news of the day. Passionate views, pointed criticism and critical thinking are welcome. Name-calling, crude language and personal abuse are not welcome. Moderators will monitor comments with an eye toward maintaining a high level of civility in this forum.

    2. You rambled, failed to stay on topic or exhibited troll-like behavior intended to hijack the discussion at hand.

    3. YOU SHOUTED YOUR COMMENT IN ALL CAPS. This is hard to read and annoys readers.

    4. You have issues with a business. Have a bad meal? Feel you were overcharged at the store? New car is a lemon? Contact the business directly with your customer service concerns.

    5. You believe the newspaper's coverage is unfair. It would be better to write the editor at editor@helenair.com. This is a forum for community discussion, not for media criticism. We'd rather address your concerns directly.

    6. You included an e-mail address or phone number, pretended to be someone you aren't or offered a comment that makes no sense.

    7. You accused someone of a crime or assigned guilt or punishment to someone suspected of a crime.

    8. Your comment is in really poor taste.

    9. Don't write a novel. If your comment is longer than the article you're commenting on, you might want to cut it down a bit. Lengthy comments will likely be removed.
