Press Release #7

April 20th, 2012

And it's done! Well, almost.

Final Presentation
We gave our final presentation this past Wednesday and it was certainly a memorable experience. The audience seemed to enjoy it and we were able to work with Purdue's Catering Facilities to have a 16" stage put in so that we could hold our presentation in a "panel" format. We'd like to send out a thanks to Epiphany Link who went directly after us, and was nice enough to work with us so that we could realize our idea without interfering with their presentation.

We'd also like to congratulate all of the 411 groups who have gone, and wish luck to Ovation and Novel Ink who are presenting today.

With our Final Presentation out of the way we can finally finish filling in all of the necessary forms for our Open Source OTC papers.

Final Paper
We're having one last big meeting to push the rest of the necessary paperwork for 411/450 out the door. Grant and Joe will be taking care of OTC and helping with the research paper that Andrew has taken charge of, while Steckel organizes all of the files they have to submit in their final packet.

Final Video
Our "Meet RTR" series has been completed and we hope you enjoyed it. Come back next week for our final press release and to see the video of our Final Presentation!

Press Release #6

April 13th, 2012

Our OTC paperwork is just about finished. There are only a few date-sensitive events that need to pass for us to complete it and we’ll be submitting the open source paperwork afterwards.

Undergraduate Symposium
This past Tuesday we attended the Undergraduate Research Poster Symposium. It was a great experience and we’d like to extend our congratulations to Unistruk and SICM for winning awards.

Paper .8
Our paper is getting closer and closer to completion. All that’s left is to put in the final results and edit our bibliography and we’ll have our first submission fully done.

Final Presentation .9
We’re just about done putting together our Final Presentation and it’s looking great! Come see us this upcoming Wednesday, April 18, from 2-3PM in STEW 302.

We’ve completed our testing and compiled the data. Come to our final presentation to find out more!

RTR has begun reaching out to professionals to review our portfolios. Four years of work (more for some) is starting to come to a final culmination!

We still have some stock left. Grab the last 498 shares before they’re gone. The price is still going up and will make good for a last-minute investment for the semester.

We have lots of videos for you to enjoy this week. Our Pecha Kucha for anyone who happened to miss it, a Bonus Video giving a glimpse of us working on our product, and the Final Meet RTR Video.

Press Release #5

April 6th, 2012

The OTC papers are done with the exception of the details that must be completed after the presentation.

Joe and Andrew will be attending this semesters IAB meeting. They will be presenting about the experiences they have had with CGT 411/450 and the CGT department

Pecha Kucha
Our CEO Joe has taken charge of our Pecha Kucha presentation and it’s looking hilariously good! Keep an eye out for it as a video next week as Steckel plans to film it today.

UG Symposium
Our Undergraduate Research Symposium Poster has been printed and we’re signed up to be judged this upcoming Tuesday.

Corp Payroll Reconciled - Taxes
And thus Black Friday is upon us! We got to find out just how terrible the real world as as all of our accounts were wracked with taxes. It took a bit of “it’s my money and I want it now!” finagling with the corporate account, but everyone is squared away and good to go in terms of appeasing the Federal Government of Burton.

Our Product is coming along nicely during its testing stage, though that’s not to say it’s been smooth sailing. Who knew that you could accidentally render out in stereo?

Final Presentation
We’re continuing to prep for our final presentation and have outlined the topics and subjects we’ll be covering, including how Steckel seems to happily be doing everything except working on the product. We’re all pretty happy with the arrangement as it lets the RTR Programmers devote all of their time to making the product the best they can without having to worry about silly things, like taxes.

Return on Investment Update
We’ve finally gotten numbers wrangled together in terms of our product and the marketplace! The numbers were difficult to find, but we were able to find approximate data for both educational and studio licenses, giving us a total market of about 62 thousand licenses to sell. Taking the average cost of the license, we were able to determine that we would only need to sell to about 17% of the total market to make a 10x Return on Investment! However, we still need to keep in mind that this is a very specific tool for a very niche market, one that may not even exist yet.

Info Transmit
We recently had a meeting with Benes to give him an update on our product and he gave us some pointers on where to head from here. All in all he seemed very happy with our progress and we were able to have him sign off on some cogent for reaching our testing stage.

Press Release #4

March 30th, 2012

We have completed our product! Our GPU ray tracer successfully supports reflection, refraction, and adaptive sampling. We will be starting our testing next week.

Final Presentation
Our final presentation has been scheduled for Wednesday April 18, 2012 from 2-3PM. It will be located in Stewart 302. We look forward to seeing you there. We have also just submitted for new posters to be printed. Keep an eye out for them, as our CEO stepped up and made them quite snazzy.

Finalized Methods
We will be testing the performance capabilities of our gpu ray tracer on a number of different Nvidia GPUs. Each card will run through identical iterations of several 3D scenes and record the average amount of time taken to render a frame. Each 3D scene will have a different level of complexity from one another. We will be rendering scenes of increasing complexity to the point at which the ray tracer can no longer render an average of one frame per 100 milliseconds.

We have met with our statistical consultant and discussed our testing methodology. We are prepared to gather our results.

We have finished the OTC paper work for an open source project as recommended by Matt at Tech Ventures. It will be sent out early next week.

Paper .4
Our paper is being updated as we continue our project. All that we are missing now is the data that we will be collecting.

Corp Payroll
Our CFO got a little ahead of herself and was using a different set of information regarding witholding and taxes than was given to the class this past Wednesday. Calculations have been made and the next check to both employees and the Federal Government of Burton will correct RTR’s Finances.

Return on Investment
We are continuing to look into our Return on Investment. We’re now researching what percentage of the market would have to purchase our product to make a 10x return on profit.

Info Transmit
Professor Benes is out of the country this week; we’ll be meeting with him this coming week to inform him of our product completion.

Joe’s Article
Joe Finished his article entitled “Interactive Ray Tracing And Its Place In Games & Animation” for the IGDA’s “Perspectives” newsletter. It will be published in April.

We’d just like to send out a thank-you to Early Bird Studios for taking care of the CGT 411/450 Portfolio Site.

New Video
The “Meet RTR” video this week asks the team what sort of internships and jobs they’ve had.

Press Release #3

March 22nd, 2012

It took us a bit to get everyone organized and our activities submitted but we can officially say that RTR Interactiv is CITI Certified!
Since we’re working with computers and not doing any testing on humans, we are exempt from filling out IRB forms.

Individual Account Reconciliation
We’ve all taken a look at our real-life finances and applied it to the cogent system, reconciling our individual cogent accounts to reflect living in the real-world a bit more.

Group Account Reconciliation
Our CFO, Steckel, has also been busy reconciling the company’s account. RTR’s financial structure now also includes withholding the appropriate amount of cogent from the employees’ weekly checks (taxes for federal, state, county, Social Security, and Medicare) and sending that money along with the company’s match for SS and Medicare to the Federal Government of Burton. The first check was a bit of a bite because we had to make up for the 8 weeks that we’ve been a group. We trust that he is using it well.

We are currently in the process of filling out our OTC papers for Open Source Distribution of our final product and the benchmarking software that will come with it.

Return on Investment
Grant has done research into what it would take for RTR's product to be profitable. We looked at the possibility of our product being three different versions: Educational ($99.99), a Standalone Studio License ($750.00), and a Studio IP Development ($2,500,000.00). In order to get a 10x return on investment, we would have to sell either 45,393 educational licenses, 6,052 Standalone Studio Licenses, or just 2 Studio IP Development Licenses! Those are some very encouraging numbers!

Resume Reviews
Every member of RTR Interactiv has contacted at least two members of the professional community to have our resumes reviewed. The feedback was invaluable and our resumes have evolved accordingly.

Paper Rough Draft v1
The preliminary version of our paper has been submitted.

Andrew has journeyed to the land of the STATS department and our application to have a STATS Graduate Student look at our data has been submitted.

We’re still working hard on our product. There’s not a lot of news to report on it, except to say that we’ve made a lot of progress on learning the OptiX structure. Expect some cool stuff coming soon!

Info Transmit
We’ve sent a short update to our mentor, Prof. Benes, to let him know that we’ve not forgotten him! More information will be available and a full update will be given on Monday.

All of our personal portfolio sites (which you can see by checking our team page) have been submitted to Burton for when the CGT Portfolio Site becomes updated again.

Registered for Poster Symposium
We’ve successfully registered for the Undergraduate Research Poster Symposium! Look for our poster when it happens on April 10, 2012.

SIGGRAPH Involvement
This past Tuesday RTR Interactiv was the main focus of Purdue’s student SIGGRAPH Chapter as we spread the word and got people excited about our project. There was even some cogent given out to some of the lucky attendees.

Our stock disappeared faster than cupcakes at a sweet-tooth convention! All of it was effectively gone and sold in less than 48 hours. If you still haven’t bought any and are interested we wish you the best of luck when the next wave of stock is released.

Joe's Experience At SxSW
“My experience at SxSW Interactive was amazing. I got a chance to go to NCSoft, Bioware Austin, and Junction Point as well as meet some prominent figures in the games industry such as Warren Spector (System Shock, Deus Ex, Epic Mickey), Phil Fish (Fez), and Adam Saltsman (Cannabalt). I even met a few other people who have started to delve into real-time and interactive ray tracing.”

Official Publicity!
Our CEO, Joe, is currently writing up an article to be published in the April issue of the “IGDA Perspectives” newsletter. We are helping him in any way that we can and look forward to seeing his publication.

New Video
The “Meet RTR” video this week covers why the members of RTR ended up at Purdue University.

Second Wave is Gone

March 21st, 2012

Just an update for those of you watching the site that our second wave of stock is officially gone. We wish you luck purchasing stock when the third wave of another 6,000 shares eventually hits.

CFO of RTR Interactiv

And it's Gone Again...?

March 20th, 2012

Hello everyone. This is an update on our stock situation. If you'll glance to the right of your screen, you will see that we have no stock available but have only sold 9,000 out of our 12,000 stock that we've been given. How can this be? Two reasons. We currently have 2,300 stock that are in transfer, meaning that people have said they're going to buy it and we're just waiting for cogent to change hands and become finalized.

There is also 700 stock that I have set aside in reservation for a couple of people who tried to get stock before but weren't fast enough (this is to note that there was stock when they emailed, but not by the time I got to their request chronologically). If they don't respond by Friday, that stock will open back up to the public.

In short, keep an eye open and keep trying for those who haven't been able to get stock these first two times. I'll do my best to keep the stock info here on the website as up to date as possible.

Press Release #2.5

March 16th, 2012

It's Spring Break here at Purdue University and it's been an eventful time. Joe had his South by SouthWest Interactive conference, Grant went back to California, and Andrew also traveled home. Steckel's work at both the Envision Center and Mackey kept her here over break, but that means that we have an extra video to show you guys! Enjoy.

Press Release #2

March 9th, 2012

Business Documents
With all of RTR's formation documents done and a financial structure in place, our company is in full swing with employee, mentor, and Purdue contracts, a payroll, and stock. Our stock was so popular we sold out in less than 48 hours!

Our methodology has been finalized and narrowed down from its original scope. We will be testing our ray tracer on a number of different NVIDIA GPUs and recording its performance while it renders a number of 3D scenes. We intend to increase the complexity of each scene in terms of materials used, poly count in view of camera, and number of rays cast per second.

Staying true to common benchmarking methods, each scene will consist of a Cornell box using one or more copies of the Stanford bunny model. We’ll be testing the ray tracer with more and more complex scenes until its performance is no longer satisfactory. We will be able to find the highest level of scene complexity that the GPU ray tracer can handle while still maintaining the illusion of movement.

We’ve been making progress on the product itself. Currently, it supports obj model imports with mtl files, lambertian and phong material types, and interactive light and camera movement. The current features in development are an interactive UI and a custom material shader that can support any surface type. Global illumination techniques are also being explored. A rudimentary global illumination implementation has been tested and proven to be possible, but we’re keeping this on the backburner for now.

Lit Review
We've learned a lot about interactive ray tracing and ray tracing acceleration techniques from our research. In fact, it is fair to say that our project has evolved based on what we have learned in the research. First and foremost, we have defined the limits of what does and does not constitute interactive ray tracing. This has helped us not only define our product but also our testing methodology. We have also discovered several methods for improving the speed of various GPU rendering functions. This was one of the most helpful areas of research for us when defining the realistic goals and expectations for our production schedule. Many of the techniques, such as point-based global illumination, would be ideal to implement but might not be reached due to time constraints now that we know the complexity behind such an implementation

We'd like to give a huge wave of digital-press support to Joe who is currently in Austin Texas attending the "South by SouthWest Interactive" conference. We're looking forward to hearing from him and learning more about his experience.

And here is the first video in our new series being put on by our Media Guru, Steckel.

Meeting RTR: How did you become involved with RTR Interactiv?

And it's Gone!

March 6th, 2012

Less than 48 hours after class let out on Monday, all of our stock is sold! We're currently working on getting more and will let you know when it's available.

For those of you lucky enough to get your hands on some before it all disappeared, I will have the stock certificates ready to pick up on Wednesday during 411.

Press Release #1

March 1st, 2012

With our Go/NoGo a success, RTR is able to move full-steam ahead with our product. We will still be creating and doing testing with a raytracer on the GPU, but our end product has changed and is much more exciting! From our research, lit review, and our discussions with our mentor, our methodologies have become more clear and - more importantly - our end product has evolved. By the end of the semester, we plan to have an executable file that will tell the user how well their system can handle raytracing (based off of the testing and benchmarks that we will be using).

Stocks will soon be posted.

Stay tuned as well as our Media Guru, Steckel, kicks it into high gear and begins the release of a series of videos to get you a bit more acquainted with the RTR team.

Follow us on Twitter, like us on Facebook, or just drop by the site every now and then to see what's new and exciting.
