A raytracer to shade topographic maps in R

In plain words

This R package implements raytracing to create shaded relief visualizations of topographic maps. It applies illumination techniques to elevation data to produce three-dimensional-looking map renderings. The tool is designed for cartographers and geospatial analysts who want to enhance the visual presentation of terrain data using computational methods previously considered too expensive for routine use.

W hen reading older scientific literature, I occasionally run across a statement that never fails to capture my interest. “This method is computationally expensive and should be avoided.” -A statement made around the period Chambawamba captured the zeitgeist of the 90s . These statements are of a particular interest to me in fields where computation is simply a means to an end and not the main focus of researchers–this means that potentially, the issue hasn’t been revisited since it was originally declared algorithm non grata . The last couple decades have delivered us some incredible improvements in CPU power. Algorithms that may once been seen as unworkably greedy may–especially with the…from tylermw.com

  Every mountain, building and tree shadow mapped for any date and time2024 · shademap.app · ▲685

  I've been working on this project for about 4 years. It began as terrain only because world wide elevation data was publicly available. I then added buildings from OpenStreetMap (crowd sourced) and more recently from Overture Maps data. Some computer vision/machine learning advancements [1] in the past few years have made it possible to estimate tree canopy heights using satellite imagery alone making it possible to finally add trees to the map. The data isn't perfect, but it's within +/- 3 meters of so. Good enough to give a general idea for any location on Earth. Happy to answer…

  I've made a Monte-Carlo raytracer for glTF scenes in WebGPU2024 · github.com · ▲131

  This is a GPU "software" raytracer (i.e. using manual ray-scene intersections and not RTX) written using the WebGPU API that renders glTF scenes. It supports many materials, textures, material & normal mapping, and heavily relies on multiple importance sampling to speed up convergence.

  3D Terrain simulation for hiking, skiing etc.2025 · github.com · ▲150

  I'm working on a GPS track visualizer for quite some time. It shines in hilly and mountaineous terrain (where a 3D view makes more sense), but it also offers quite a lot of Strava-like features (statistics etc.). You can upload your GPX and FIT files manually, or sync directly with Garmin, Coros and Polar. See https://cubetrek.com for the live app and check out some examples there. It's free and opens source. Also, anyone who likes to work with 3D visualizations (especially Babylon.js), let me know if you like to help polish this thing further.
