In their own words
Picogen
Picogen is a free outdoor ray-tracing system for generating large terrain scenes with realistic illumination across day and night and detailed plant populations. It supports procedural scene work through SSDF userspace scripting and heightfield objects. Implemented rendering choices include Whitted-style rendering and path tracing. Materials include fully diffuse Lambertian and perfect mirror specular types, while Height-Slang programmable materials and shaders support terrain. A sun-sky global setting controls scene lighting, and cameras provide yaw, pitch, and roll controls. Picogen is licensed under GPL version 3 or later and runs on Linux and Windows. Linux downloads include 32-bit and 64-bit packages for Debian, Ubuntu, and similar distributions, plus tarballs. Windows offers an installer and portable zip or 7zip archives. Source code, a no-signup forum, and wiki documentation are available. The roadmap lists several features as unimplemented, including a graphical interface.
