The author discusses their decision to put their project, Tangerine, on hold and develop a new renderer called Star Machine, an eccentric CPU ray tracer. Star Machine can effortlessly handle 4k frames at 120hz, has a unique visual style, and a custom coordinate system with a constant world resolution. They introduce a time trial racing game called Rainy Road but face challenges with terrain rendering requirements. The author explores generating terrain surfaces from splines in Blender, presenting a theoretical solution. They provide code snippets, illustrations, example files, and discuss the implications of their technique including a real-world implementation and examples of its application.
