Computer Graphics: Opengl

Project for POGL and POGLA course at EPITA made by Dominique Michel et Lea Masselles

What is it ?

This is a 2-person group project where we implement basic OpenGL features and then add some more complex afterwards.

The basics features are:

• Sample scene with objects
• Skybox
• CPU particle system campfire
• CPU particle system firework

The advanced features are:

• GPU particle system campfire
• SSAO (Screen Space Ambient Occlusion)
• DOP (Depth of field)

Setup

To be able to compile and run the program you need :

• CMake (build system)
• OpenGL (library)

Setup the build system and compile the project:

42sh$ cmake -B build_folder -DCMAKE_BUILD_TYPE=[Debug|Release]

Usage

Running the program

Run the project with ressources in current directory:

42sh$ cd build_folder && ln -s ../res/* . && ./myOpenGl
42sh$ # OR
42sh$ cd res && cp ../build_folder/myOpenGl . && ./myOpenGl

Interactions and movements

• WASD for first person movements

• MOUSE for first person head rotations

• ESPACE to fly upwards

• CTRL to fly downwards

• MOUSE Wheel control flying speed

• P print camera position

• ENTER toggle fireworks

• O toggle SSAO

• F togle DOP (settings can be set in dop_pass.glsl) focusSettings = vec3(-30, 15, 5) with x = position of focal point y = half-length of clear zone z = length ofthe clear / blur transiation zone

Known issues

• Code could be better done a structured but this remains my first real opengl
