C++ version of Lum is abandoned - project was rewritten to Rust. It might be revived later.
I also rewrote it to use modules

Lum is a simple voxel* renderer** built with Vulkan

• Intel Iris XE (integrated gpu!) - <7 mspf in FullHD
• NVIDIA 1660s - ~1.6 mspf in FullHD

• Clang 20+ compiler
• CMake 4.0.2 or newer
• Ninja
• Vulkan support

cmake -S . -B build -DCMAKE_BUILD_TYPE=Release -GNinja
cmake --build build
./build/demo

• WASD for camera movement
• Arrows for robot movement
• Enter for shooting particles
• 0 to remove block underneath
• 1-9 and F1-F5 to place matching blocks (btw world is saved to a file)
• "<" and ">" to rotate camera
• "Page Up" and "Page Down" to zoom in/out
