At the beginning of this week, I worked on reviewing Grace’s presentation to prepare for the Proposal Presentation on Monday. We discussed pacing, and the points we should mention for each of the slides. Later this week, I have researched some of the materials for constructing the pyramid. There seems to be many ways to build this pyramid such as glass. However, after considering the size that we want this to be constructed as and how it would be very difficult to construct and cut into. It seems that the other way, which might be what we will be pursuing for our design would be to use plexiglass panels since these are cheap, light and comes in big sizes. As shown in this link here, this material maintains the holographic effects, while has the potential to be scaled bigger.
I also looked into some cameras options for our design. At first, we have the options of choosing between USB, NTSC or VGA protocol to interact with our board. We think that between the three of these protocols, VGA might be easier to implement. I looked up some of the potentials options for VGA cameras and the OV7670, OV7725, or OV5642 all seem to be very viable options to meet our budget, as well as the specs for our requirements. The OV5642 seems to be much more expensive than the other two, however with 60fps support in the specs sheet. The OV7670 only has 30fps as mentioned in the specs sheet, however, it seems that we should be able to clock it up to 60fps. This camera model also seems to be more common amongst people who use FPGA with this camera as comparing to the other two camera. The OV7725 also seems to support 60fps but not a lot of people seems to have used them. Because of this, the OV7670 seems to be a viable solution for our requirements due to its cost, and widely used by people with FPGA interactions.
