search for: ignoreext

Hi, i was wondering if there is a way to annotate rgl plot, after searching i haven't found anything suitable. I saw function text3d but was thinking more about text on the margin, so not interactive. Thanks -- View this message in context: http://www.nabble.com/Annotation-rgl-plot-tp22930428p22930428.html Sent from the R help mailing list archive at Nabble.com.

...Y <- seq(from = ylim[1], to = ylim[2], length.out = resolution) Z <- outer(X, Y, f) ## Create 3d scatter plot and add the regression surface open3d() with(data = data, plot3d(x = vars[2], y = vars[3], z = vars[1], xlim = xlim, ylim = ylim, zlim = zlim)) par3d(ignoreExtent = TRUE) surface3d(X, Y, Z, col = "blue", alpha = .6) par3d(ignoreExtent = FALSE) return(summary(my.model)) } -- Joshua Wiley Ph.D. Student, Health Psychology University of California, Los Angeles http://www.joshuawiley.com/

Dear folks, I have created a plot on RGL device :   x = 1:6 y = seq(-12, 5, by=1) z = matrix(0, length(y), length(x)) z[13,3] = 1; z[13,4] = 1.011765 surface3d(x, y, t(z), col=rainbow(1000)) grid3d(c("x-", "y-", "z"))   Now I want to draw 2 lines along x=3 & x=4, over the surface (with different colour). Could somebody help me how to draw that?   Thanks,

Dear all, Below is some code where I try to get plotmath symbols in an rgl plot. Duncan Murdoch kindly suggested to use a "sprite" for this. As you can see, on can get it to work, but my knowledge about grid and rgl is too limited to perfectly solve the problem. 1) As you can see (please rotate the plot a little bit so that (0,0,0) is "in front"), the quality of the .png
