Basics of OpenGL Labs

Few OpenGL apps written in C++ during OpenGL course (Grafika Komputerowa) at the university.

Author: Bartosz Rodziewicz

The last class was about WebGL and files from that class are included in this repo as well.

Map of the repo

This repo consists of grafika/ directory which is CLion project and single *.cpp files in /. *.zip files contains WebGL stuff. tekstury directory contains image files that can be used as a textures for some of the tasks. LabTasks directory contains lab task descriptions (in Polish).

To make use of *.cpp files take the one you want to open, change the name to main.cpp and paste it in grafika/. Then run CLion, compile and run.

To make use of *.zip files just extract them and open index.html. Sometimes you may need to use browser different than Chrome (especially for lab7-6.zip).

Tasks done during the course

Every single *.cpp file in / is one single task. There are two groups of those tasks:

• lab#-#.cpp/zip are tasks copy-pasted from lab task instructions,
• others are tasks that we had to do by ourselves and those were:
  • sierpinskiCarpet.cpp - simple app that draws Sierpinski carpet (user can chose number of steps and perturbation level),
  • egg.cpp - app that draws egg model,
  • teapot.cpp - app that draws teapot that you can move with a mouse,
  • egg-cameraMouseSpin.cpp - app that draws egg that you can move with a mouse,
  • egg-light.cpp - app that draws egg and puts a light on the object,
  • egg-lightMovement.cpp - app that puts two light sources on the egg model which position can be change with a mouse,
  • tetrahedron-texture-mapping.cpp - app with a tetrahedron that have mapped texture on,
  • egg-texture-mapping.cpp - app with an egg model that have mapped texture on,
  • WebGL-tetrahedron.zip - webGL app that draws a tetrahedron,
  • WebGL-slowDownAnimation.zip - webGL app that draws a cube with a texture mapped on and fixed bug that makes it spin faster every time you re-run it.

CLion Configuration

Before running those files in CLion you have to configure it and install required plugins.

• Make sure you use CLion with MinGW.
• Download required plugins:
  • pkg-config
  • glib
  • gettext-runtime
  • freeglut
• Unpack them to MinGW directory (where MinGW is installed).
• Looks like it's all you have to do.
