I saw that in rgl:::writeWebGL that "Polygons will only be rendered as filled; there is no support in WebGL for wireframe or point rendering.". I found that you can easily use contour3d to make reproducible contour web figures, such as (taken from contour3d help)library(AnalyzeFMRI) a <- f.read.analyze.volume(system.file("example.img", package= "AnalyzeFMRI")) a <- a[,,,1] contour3d(a, 1:64, 1:64, 1.5*(1:21), lev=c(3000), alpha = c(0.2), color = c("white")) browseURL(paste("file://", writeWebGL(dir=file.path(tempdir(), "webGL"), width=500), sep="")) But I found problems with multiple levels, such as contour3d(a, 1:64, 1:64, 1.5*(1:21), lev=c(3000, 8000, 10000), alpha = c(0.2, 0.5, 1), color = c("white", "red", "green")) browseURL(paste("file://", writeWebGL(dir=file.path(tempdir(), "webGL"), width=500), sep="")) Does anyone know why this happens, or a way to fix it (maybe using separate = TRUE for contour3d)?
Why what happens?
