I have a set of 3D coordinates (below - just for a single point, in 3D space): x <- c(-521.531433, -521.511658, -521.515259, -521.518127, -521.563416, -521.558044, -521.571228, -521.607178, -521.631165, -521.659973) y <- c(154.499557, 154.479568, 154.438705, 154.398682, 154.580688, 154.365189, 154.3564, 154.559189, 154.341309, 154.344223) z <- c(864.379272, 864.354675, 864.365479, 864.363831, 864.495667, 864.35498, 864.358582, 864.50415, 864.35553, 864.359863) xyz <- data.frame(x,y,z) I need to make a time-series plot of this point with a 3D rendering (so I can rotate the plot, etc.). The plot

I would like to create an interactive 3D surface plot of depths in a lake, ideally using the plotly or rgl libraries. I have extracted my data from a SpatialLinesDataFrame of contour lines in Gauss-Krueger/EPSG:31468 CRS, i.e. metric units. Now each contour line produces a set of coordinates with the same depth value. The resulting data frame is rather large, but looks something like this: set.seed(41) xx <- rnorm(100,4448929,100) yy <- rnorm(100,5308097,100) zz <- c(rep(-10,10),rep(-20,10),rep(-30,10),rep(-40,10),rep(-50,10),rep(-60,10),rep(-70,10),rep(-80,10),rep(-90,10),rep(-100,10)) df <-

Package rgl includes a very useful function ellipse3d , which can return an ellipsoid that cover like 95% percent of the points in 3D. Then this object can be used in rgl::plot3d to plot it out. My question is that is it possible to convert the output of ellipse3d to something that can be plotted through js plotting packages like plotly? library(rgl) dt <- cbind(x = rnorm(100), y = rnorm(100), z = rnorm(100)) ellipse <- ellipse3d(cov(dt)) plot3d(dt) plot3d(ellipse, add = T, color = "red", alpha = 0.5) Then what can I do to plot the ellipsoid through plotly? You can extract the coordinates of

I am currently using the rgl package for some data representation. Here's my command mypath("directory") png(file=mypath, res=600, width=10.5, height= 10.5,units="in",bg = "transparent") require(rgl) set.seed(1) df <- data.frame(replicate(4,sample(1:200,1000,rep=TRUE))) colnames(df) <- c("var1","var2","var3","var4") plot3d(x=df$var1, y=df$var2, z=df$var3, col=as.numeric(df$var4), size=0.5, type='s',xlab="var1",ylab="var2",zlab="var3") rgl.snapshot(mypath) The command above works and produces a tiny image, which I wasn't able to make bigger, or increase its resolution (to 600). I have also

Attempting to compile rgl for r on arch linux x86_64. I copied just the error portion of the installation. This has occurred after I recently updated R.

How can one plot a sphere in R by providing a center point and a radius? For example, something like this: sphere_3d(center=c(1,1,1), r=2)) The plot would appear on a three dimensional coordinate system. Try spheres3d in the rgl package for an interactive plot: library(rgl) spheres3d(x = 1, y = 1, z = 1, radius = 1) There are many other ways, so what's going to be useful needs more input. Jeromy Anglim Adapted from @mdsummer 's answer, this also adds axes. library(rgl) open3d() # create new plot spheres3d(x = 1, y = 1, z = 1, radius = 1) # produce sphere axes3d() # add x, y, and z axes Take a
