LOD terrain renderer using mesh shaders via Vulkan (thesis project)
When cloning the repo, remember to use the --recurse-submodules as imgui is also cloned as a git submodule.
In order to build the project, the following are required:
- Support for vulkan 1.3 and vulkan-sdk
- SPIRV-Tools
- GLFW 3
- GLM
In order to build the project execute the following commands:
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=<BUILD_TYPE> --preset <BUILD_TYPE> -S . -B ./build/<BUILD_TYPE>
cmake --build --target terrain_renderer --preset <BUILD_TYPE>
Additional options can be added when calling the first cmake command by adding -D<Option name>=ON:
DRAW_WIREFRAME- draws the terrain in wireframe.
In order to use the app, traverse into the built binary directory. Next create a heightmaps folder like the one in the root directory of the repo and copy desired SRTM heightmaps inside. An example heightmap is also included in the heightmaps directory. The program will load the heightmaps inside the directory - note this is not a recursive action so subdirectories won't be searched. Other SRTM heightmaps can be found at the coverage map site.
In order to set the starting coordinates of the observer, use the --starting-position argument along with coordinates in the same format as the naming convention of SRTM files (e.g. N42E014).
To move around, use the WASD keys, E and Q to rotate the camera and Spacebar and Left CTRL to gain and lose altitude respectively. In order to move faster, hold the Left Shift key while performing the movements.
