3D mapping, plotting, and printing with rayshader
summary
Rayshader is an R package that ray traces elevation matrices to produce shaded topographic maps, render them as solid 3D meshes with plot_3d(solid = TRUE), and export to 3D-printable formats and gltf 2.0 for web/Blender. It layers raytraced shadows, ambient occlusion, water via detect_water/add_water, and image overlays, adds depth‑of‑field postprocessing, and handles bathymetry; the presenter shows printed Hobart models that closely match renders and reports finding tricky floating‑point bugs by examining animation frames.
