Questions tagged [rgl]

`rgl` is a 3D visualization device system for R, using OpenGL as the rendering backend.

The rgl package is a 3D visualization device system for R based on OpenGL. An rgl device at its core is a real-time 3D engine written in C++. It provides an interactive viewpoint navigation facility (mouse + wheel support) and an R programming interface.

Features:

  • Cross-platform (Mac OS X, Win32, Unix/X11)
  • R programming interface
  • Interactive viewpoint navigation
  • Automatic data focus Geometry primitives: points, lines, triangles, quads, texts, spheres, 3D sprites, particles, terrain
  • Up to eight light sources
  • Alpha-blending (transparency)
  • Side-dependant rendering
  • Texture-mapping with mipmap support
  • Environmental effects: fogging, background sphere
  • Bounding box with axis ticks marks
  • Undo operation

Inputting a fixed colour input vector with RGL in R

Is there any way to input a fixed vector of colours to any 3D rgl plots? If so it would be possible to extrude a map tile to a 3D surface based on a raster of the same area. But I'm finding the surface3d function behaves the same as raster::plot…
