A procedural planet generator powered by OpenGL build in C++. Uses the GLAD and GLFW libraries for OpenGL functions and window creation
The planets are generated using several value noises overlayed on top of each other which then offset the height of each vertex
The color is then decided with a palette of materials based on height. Each material has its own ambient, specular and diffuse color along with reflectivity
Each planet can also have an atmosphere which reacts to lighting and player proximity
The entire rendering pipeline is made from custom OpenGL wrappers which were designed to be flexible in almost any scenario
They can streamline manipulating with OpenGL buffers, shaders, framebuffers, vertex arrays and more
- OpenGL - rendering
- glfw - basic window & input management
- glad - access to OpenGL functions
- glm - OpenGL math library
- Dear ImGui - testing UI
- stb image - image decoding
- assimp - model loading
To build and run this project you will need to have the following installed
- VCPKG
- On Windows it is preferred to have the VCPKG_ROOT variable set
- CMake
- Ninja
- GCC
- OpenGL 4.6.0 or greater
cmake -S . --preset release
Note
If you do not have VCPKG_ROOT enviroment variable configured use the following command instead:
cmake -S . --preset release -DCMAKE_TOOLCHAIN_FILE="PATH\TO\VCPKG\CMAKE\vcpkg.cmake"
To build all files (or any changed files later on) run
cmake --build build
cmake -S . --preset release-linux -DCMAKE_TOOLCHAIN_FILE="/PATH/TO/VCPKG/CMAKE/vcpkg.cmake"
To build all files (or any changed files later on) run
cmake --build build
The build directory includes the executable file called PlanetGenerator.exe or PlanetGenerator
