Doing a visual graphic and trying to make it "pretty" Here's simple chart to play with: library(rgl) dotframe<-data.frame(x=c(0,7,0,0,-7,0),y=c(0,0,7,0,0,-7),z=c(7,0,0,-7,0,0)) dotframe plot3d(dotframe$x,dotframe$y,dotframe$z, radius=3, type='s',col=c('red','green','blue','purple','orange','gray'), axes=FALSE, box=FALSE,

Hi everyone, I want to plot a 3D interpolation of the concentration of aquatic organisms. My goal would be to have the result represented as clouds with a density proportional to the abundance of organisms, so that I could fly (well, swim actually ;) ) through the scene and see the patches here and there. Basically, I want to do something like this: http://www.youtube.com/watch?v=27mo_Y-aU-c but

Hello, While exploring if rgl is along the lines of what I need, I checked out demo("rgl") and didn't find quite what I'm looking for, and am therefore seeking additional help/suggestions. The application is geared towards displaying a 3D rendering of a contaminant plume in the subsurface with the following highlights: Once the plume was rendered as a 3D object, a

.... rgl doesn't make everything in OpenGL available. I'm not sure exactly how those clouds were done, but it wouldn't really be easy to do them in rgl. I think you can come closest to what you want within rgl by using sprites rather than rendering transparent spheres. See examples(sprites3d).
