Image Scaling Test Is Go...

So JT and I spent today making a new testing file that is specific to scalability testing. First we ditched JPGs, and 32 bit BMPs because they were having problems and were just overall not viable formats. Then we made versions of every remaining image format at 4 different resolutions, 1 set at the original resolution, 1 set at a resolution that was 2 times as large, 1 set at a resolution that was 4 times as large, and finally 1 set at a resolution that was 1.73 times as large so that if the fu ...

WeekTwo.start()

So it is the beginning of week 2. This week JT and I plan on finishing up the final test for the animation frame rates. In this final test we have multiple objects animating simultaneously and it auto-runs all of the different formats for us. This new version really simplifies the process and is pretty easy to add more functionality to. Once the test is complete we will move into testing scalability of images and the best ways to scale images. We don't currently know exactly how we will test sca ...

Four days in and things are great...

So today JT and I ran tests on all of the various formats we had decided to look at, except SVGs, and we learned a lot of useful information we did not previously know. First and foremost we learned that bmp, while a larger format when it comes to file size, is easily the best for performance. It constantly performed almost two times better than every other format in every test. We also learned that when we used images with transparency, whether it was built- in with the format or rendered to lo ...

Success!

So after a long and fruitless process we finally finished retooling the first animation test tool. The current version displays the average time it takes to display a frame which we can then use to determine how many frames are being displayed each second. Later tonight JT plans to continue refining the program so that it gives us this information directly and so that it works for all of the file formats. Ideally tomorrow morning we will have preliminary test results that will tell us how effect ...

It may still be the third day but...

So it is still the third day but I thought the blog deserved an update for what's going on right now. Basically JT and I have run into a problem with our testing. Our original plan for testing was to have an image on the screen that was moving across the screen in a specific pattern and was constantly cycling between a set of images. Then once the test program was up and running we would then use the terminal program, 'htop' to record the CPU cycles and memory use. The goal here was to determine ...

Third time's the charm...

So it is the third day and JT and I are on track to start testing today and continue through with that till tomorrow. Yesterday we made a test program and we are now working towards enhancing that program to fill some needs we did not think of yesterday. I will put out more updates as far as how our tests are going tomorrow. ...

Day Two...Initiate

So it is 10 AM the second day of the quarter and I am getting ready to start working. Last night I took the time to recreate all of the Fortune Hunter images in 9 unique formats which included, 3 different types of BMPs, GIFs, PNGs, and 4 different levels of quality of JPEGs. While I did that, JT setup the XO laptop so that he and I could look at the system stats while we test each type of image. So that's what we are doing today, running tests to determine what works best as an image format on ...

It's a blog...

Hi I'm David Silverman and I am working on the Art and Animation On Constrained Platforms project. JT and I have been laying out our schedule for the first week or so and things are going pretty well. I forsee a very productive summer. Have a good one -Dave ...
