3D ggplots with rayshader
summary
A pipeline converts a ggplot into a 3D surface by extracting a grayscale height matrix and feeding it to rayshader’s plot_3d so a single call like plot_gg produces a textured mesh; color or fill aesthetics both work and layered ggplots can supply separate texture and height. Rendering uses rgl rasterization for fast previews and rayrender path tracing via render_high_quality for photorealism (expect ~6–8 hours for a 12s path-traced movie and heavy CPU load). Camera motion, depth‑of‑field and 3D model overlays are supported.
