Project 2 - Shakin'

Due Monday 3/16 at 8:59pm Chicago time


The first example showed the use of VR with an architectural example with an 'inside out' metaphor . The purpose of this project is to give you experience using VR with visualization with an 'outside-in' metaphor - in this case visualizing earthquake hypocenter data.



Again we will use OmegaLib as the VR library. You should be able to do much of the work on your project from a laptop or desktop computer, but you should be sure to allow for enough time to test and refine your project in the CAVE2 and on the Rift.

Another common use of VR is to look at complex datasets where the patterns are more obvious in 3D, for example worldwide earthquake hypocenter (epicenter + depth) data.


To get a C on the project the user should be able to:

To get a B you need to add ...

To get an A you need to add ...
Also note that there is a big difference between getting something working and getting it working well. The first is not that hard. The second takes much more time. You are expected to have things working well so be sure to allocate time to test out your project in CAVE2 and on the Rift. Make sure the user can see you world with a high enough frame rate (at least 15 fps), and that the models do not flicker or have missing sides.




A good place to get data is from the USGS at http://earthquake.usgs.gov/earthquakes/search/

for example you can generate a csv file with lines that look like:

time,latitude,longitude,depth,mag,magType,nst,gap,dmin,rms,net,id,updated,place,type
2014-04-01T23:46:47.260Z,-19.6097,-70.7691,25,8.2,mww,,23,0.609,0.66,us,usc000nzvd,2015-01-28T14:44:48.195Z,"94km NW of Iquique, Chile",earthquake

You will very likely want to convert the latitude and longitude values into X, Y, Z. You can do this as a pre-processing step or within your code.



There are a variety of ways to get outline data for countries and continents on different scales. There is a fairly nice shapefile dataset at
http://thematicmapping.org/downloads/world_borders.php
which gives you the border data plus name of the region and other data which makes it possible to get the bounding box for different regions for the B requirements.

Then you need to convert the shapefile to something you can use in OmegaLib and pyShp could help you there

I will be holding office hours after class in the evl main lab with CAVE2 and the rift so people will have some time to test out your work. These sessions tend to get very busy near the deadline so its a good idea to start early.


To turn in your project you should set up a web page with several pages describing your work, including the well-commented source code and required files to be able run your program in the cave, and some photographs showing what your application looks like when its running. You should then email andy with the location of this website before the deadline. It would probably be a good idea to put a backup copy of the web page at a second website just in case I can't get to the first one.

These webpages should include:

all of which should have plenty of screenshots or photographs with meaningful captions.

Be sure to document any external libraries or tools that you make use of - give credit where credit is due.

You should also create a 2-3 minute YouTube video in the CAVE or using screen capture showing your application running and feature the video prominently on your project webpage. The video should be narrated and rehearsed to show off the important features of your project.

Remember that this website may be useful to you later on when you are looking for a job and want to show off the projects you have done.

When you send andy the location of your webpage you should also email a scaled down version of your favorite photo that is 320 pixels wide by 240 pixels tall in jpg format named p2.<your_last_name>.jpg. This image will be used on the class web pages along with the link to your project web page.



Each student will also give a short demonstration about your project in-class and answer some questions about your work. Be sure to practice your presentation so you finish within the allotted time so everyone has equal time to present.
