Before you start
This assignment uses the OpenGL graphics library together with a cross-platform OpenGL windowing library called GLFW and an OpenGL extension manager called GLEW. It also uses CMake for building. Download any of these that you do not already have. It should be possible ot do this project on Windows, Mac or Linux. If using Linux, you may also need to download a driver for your GPU from the GPU manufacturer, if the generic driver does not support the features we need.
The base code has been pushed to a GLapp directory in your class repository. This includes cmake files to try to find GLFW and GLEW. If you install them in your user directory or a place it can't find, be sure to set the GLEWDIR, GLFW32DIR, and GLFW64DIR environment variables before running cmake. There is a GUI for cmake, but I always run from the command line (Windows, Mac or Linux, all starting in the GLapp directory):
Linux (or Mac using Makefiles)
mkdir build cd build cmake .. make
Windows Visual Studio
mkdir build chdir build cmake -G "Visual Studio 15 2017 Win64" .. GLapp.sln
mkdir build cd build cmake -G Xcode .. open GLapp.xcodeproj
Try the sample code well before the assignment due date to make sure you can get it to run.
Students registered for the 634 version of the course should make a multifractal landscape, with varying roughness at different points in the landscape. You may choose to vary the roughness based on whatever you like (altitude, slope, color code from an external file, or anything else that comes to mind).
What to turn in
Turn in this assignment electronically by pushing your source code to your class git repository by 11:59 PM on the day of the deadline and tagging the commit
assn3. Do your development in the
GLapp directory, modifying the sample code.
Also include an
assn3.txt file telling us about your assignment. Include your name and campus ID at the top of this file. Do not forget to tell us what (if any) help you received from books, web sites or people other than the instructor and TA.
Check in along the way with useful checkin messages. We will be looking at your development process, so a complete and perfectly working ray tracer submitted in a single checkin one minute before the deadline will NOT get full credit. Individual checkins of complete files one at a time just before the deadline will also NOT get full credit. Do be sure to check in all of your source code, Makefile, README, and updated .gitignore file, but no build files, log files, generated images, zip files, libraries, or other non-code content.
