Dynamic Terrain using Marching Cubes

This was done as a project for the course TSKB07 at Linköping University. The project is an implementation of dynamic terrain using marching cubes.

Dependencies

To run the project a OpenGL shader version of 4.5 is required. If this version is not met, nothing will be shown on screen and error messages will be printed.

Ubuntu

Not entirely sure if these work anymore, was a long time since I used Ubuntu. But it atleast gives some hint of what is required.

  sudo add-apt-repository ppa:glasen/freetype2
  sudo apt update
  sudo apt install freetype2-demos libfreeimage3 libfreeimage-dev xorg-dev libglew-dev libglfw3-dev

Manjaro

  pamac install freeimage freetype2 glew glfw-x11

Running

To compile and run the application you need to also download my engine (verified to work on engine commit 9f8de935de83f998befbb06b9ff9e5c93bd8f232) and place it in the same directory as this project (ie ~/Documents/TIMber and ~/Documents/Greet-Engine-Port) then if you use MakeGen simply run

makegen run

in the TIMber directory to run the program.

Otherwise, you first need to build the engine inside Greet-Engine-Port/Greet-core by running

make

then compiling and running the project with

make run

in the TIMber directory.

Using the raytracer

The controls for the game is pretty straight forward. Move player with WASD, move up and down with space and shift. Move the camera with the mouse. To change which material you are placing down scroll the mouse wheel. To place out voxels in the terrain hold down the right mouse button when aiming on the terrain (this will only work within 20 units or when a striped sphere appears on the terrain). To remove voxels hold down the left mouse button.

In order to toggle the grabbing of the mouse simply press escape.
