Bonsai is a 3D voxel-based engine built with the intention of writing both fast-paced arcade games and tile/turn-based RPGs
Bonsai, and nearly all it's dependencies, are written completely from scratch. One external dependency is the C runtime library for startup, and a small handful of trig functions (sin, cos, atan2). I have a back-burner task to remove the CRT entirely, though it's unclear when/if I'll get around to it.
The only requirements to build and run Bonsai are an OpenGL 3.3+ driver, C++ compiler, and a few appropriate system headers.
Grab pre-built binaries & assets from theLatest Releases for your platform of choice (as long as it's Windows or Linux;)
