Evans & Sutherland Internship

U students create new presentations during planetarium internship .

This past summer Keegan Benfield, Ethan Lamé, and Christian Norseth, in the U’s Department of Physics & Astronomy, participated in an internship program at Evans & Sutherland, a Cosm company.

Cosm/E&S, considered the world’s first computer graphics company, has developed advanced computer graphics technologies for more than five decades.

Their technology developed Digistar 7, the world’s leading digital planetarium system, with full-dome programs and production services, giant screen films formatted for fulldome theaters, premium-quality projection domes, and theater design services.

The Physics Department had an opportunity to chat with the students about the internship.

How did you learn about the internship?

Benfield - senior: physics, mechanical engineering

I learned about it through an email from my U of U physics advisor, Cyri Dixon, the day before the internship closed. The email introduced me to Cosm. I was excited and applied right away.

Lamé - senior: physics

I first heard about the internship with Cosm from Cyri Dixon. It sounded interesting, so I thought I might as well apply.

Norseth - graduate 2021: physics

My advisor, Dan Wik, told me about the internship during one of our meetings.

What problem were you trying to solve at Cosm/E&S?

Lamé

We were given the task of creating shows using their software, Digistar. We each picked a topic to research, and then we used Digistar to program the show as if it were to be shown to a planetarium audience.

Norseth

My understanding is that Cosm/E&S put a lot of effort into adding accurate astronomical data and surveys into their planetarium software, and they wanted a way to show planetariums how to use the data.

Benfield

The astrophysics interns were assigned two projects: designing two presentations on astrological objects and compiling a research paper that complemented the productions. The goal was to demonstrate the Digistar 7 system capabilities.

How did you go about developing a solution?

Norseth

I selected two topics and researched them. I chose Extrasolar Systems and Stellar Formation Regions. We had a general outline of what kind of information we should include in our 5-10-minute planetarium show. I compiled a lot of information and then wrote out a “storyboard” with each element I wanted to include. I then designed the show in Digistar by writing automated scripts in the Digistar Command Language that controlled where you were in space and other visual elements on the dome. We could test our shows out on a projector dome that you would have in a planetarium.

Benfield

During the first week, we were instructed on how to use the Digistar 7 systems and were given a general tour of the company facilities, including their three domes. We learned the operations and usage of the medium dome so that we could test our presentations. We used the remaining nine weeks to research, develop code, and collaborate on the shows.

Lamé

After the first week of training using the Digistar software, we all jumped into using the scripting language to code our own movements and animations. After I did some research on my topic, I created a sort of story that I wanted to tell the audience, and then used the Digistar code to show the audience exactly what I wanted to show them.

Did you collaborate while still working on your own projects?

Lamé

We each worked on different topics throughout the internship, but we still helped each other. There are a lot of functionalities that the Digistar software has that we found through experimentation on our own topics, so if one of us had a question on how to do something, the others would often have an answer.

Benfield

Each astrophysics intern selected their own two topics to investigate and research on their own time. However, we regularly met at the offices to discuss our code, receive help in coding, and peer review each presentation. We could easily rely upon each other when a problem occurred. Due to the variety of options that the Digistar 7 systems offered, each intern developed a unique method of generating various celestial objects so that each of our presentations were different.

Norseth

We all worked on our own shows individually, but we helped each other figure things out. We would help each other with framing certain information or give suggestions on how to create an element in our shows.

Tell us about your daily routine .

Benfield

My work day usually started around 9 a.m. and ended at 3 p.m. The day was broken up into sections depending on the number of meetings I had that day. For the days with fewer meetings, I spent my time in the computer lab or medium dome, developing my presentations and aiding or receiving coding aid from other interns. We also reviewed each other’s content in the dome. On days with multiple meetings, I spent my time preparing and conducting a little bit of coding.When I wasn’t at Cosm’s facilities, I was at the Marriott Library, conducting online research or scouring the library for research books.Each intern was assigned a Cosm buddy—an older company member. I met bi-weekly with my buddy to discuss any problems and to review my and practice my presentations. We did have internship week, where all of the interns traveled to the facilities here in Utah. We had multiple activities, ranging from an airplane competition, designing a Cosm event, and having dinner and a movie in the large dome. We also received tips about hiring and using LinkedIn as a networking tool.

Norseth

Every week I’d come into the office on Monday, Wednesday, and Thursday and get to work in a shared computer space. If I needed to test any content on the dome, I’d export my scripts and head down to the bottom floor where I could use the projector dome.

Lamé

Typically, I would arrive just before 9 a.m. and jump into working on whatever work I had from the previous day. There were occasionally meetings during the day that we were able to join from our laptops, but for the most part, we stayed in the computer lab working on our shows. Most people were there most days, so I was rarely the only one in the room. Often, we would go to a planetarium projection dome in the office and play our shows to see how the movements/animations worked and fix any bugs that popped up. I would often be doing research on the internet while working on these projects to make sure that the information I had was correct and to search for more engaging stories to tell.

Future plans?

Norseth

I’m hoping to attend graduate school in astrophysics. This is my second year applying, but I should have a published paper under my belt this time. After my Ph.D., I’m not sure what I’ll do, probably try to become a professor or conduct some kind of astronomy-related research.

Lamé

I’m planning to apply to some graduate school programs in astrophysics and maybe even an engineering program or two. I’d love to dive deeper into a related field in grad school and once I know that I enjoy working with that skill set, eventually move into an industry job.

Benfield

I love learning and developing skills that are desirable for my career path. I want to enter the field of defense contractors or work at a national lab. I also plan on continuing my education by earning a master’s or a Ph.D. in engineering, computer science, and physics. Eventually, I want to start my own company based on some inventions that I have semi-planned out.
