- OpenGL 4 based renderer
- Simple water simulation
- Adding/removing blocks with raycasting from mouse position to 3D block position
- UI library based on HTML/CSS with flexbox layout support
Install the following tools:
- conan
- cmake
.venv/bin/conan install . --output-folder=build/conan --build=missing --remote=conancenter
cmake --preset conan-release
cmake --build --preset conan-release
Conan Center's OpenGL/GLFW packages require the distribution's X11 and OpenGL
development packages. If the first command reports missing xorg/system
packages, install the packages it lists with your distribution package manager
(for example, sudo apt-get install <packages-reported-by-conan>) and rerun it.
To choose a different render distance, configure CMake with the number of
chunks to render in each direction from the camera (the default is 15):
cmake --preset conan-release -DVOXELWORLD_RENDER_DISTANCE=24
cmake --build --preset conan-release
Larger values create and draw substantially more chunks, so they have a steep CPU and memory cost.
