Spline Distance Fields

Star Machine, a new CPU ray tracer designed to overcome Tangerine's limitations, can render 4k frames at 120hz with any scene complexity. The author is developing Rainy Road, a racing game, using spline distance fields for terrain generation. This method generates terrain from splines describing key features, providing real-time terrain effects. Blender is used to model and iterate on these techniques, allowing the generation of complex terrains. The post includes detailed steps and example files for implementing the method in Blender, emphasizing spline vector calculations.
