I'm trying to plot a 3d grid with cuboid elements (transparent using the Plot3D package of R, however I cannot find a good solution. Any suggestions? The objective is to add the 3D grid in a 3d scatterplot using the function scatter3D.
I wrote the following code which solves my problem. I used the function 'lines3D' of the Plot3D package. I'll appreciate it if you can provide a more elegant way to avoid the loops.
library(plot3D)
library(plot3Drgl)
x_grid <- y_grid <- seq(0 , 1000, 200)
z_grid<-seq(0 , 500, 100)
# plot a 3-D mesh
M <- mesh(x_grid, y_grid, z_grid)
# plot result
dev.new()
scatter3D(M$x, M$y, M$z, pch = "-", cex = 0.1, colkey = FALSE,ticktype = "detailed")
for(i in 1:length(z_grid)){
for(j in 1:length(y_grid)){
lines3D(x = c(min(x_grid), max(x_grid)), y = c(y_grid[j],y_grid[j]), z = c(z_grid[i],z_grid[i]),colkey = FALSE,add=TRUE)}}
for(i in 1:length(x_grid)){
for(j in 1:length(y_grid)){
lines3D(x = c(x_grid[i],x_grid[i]), y = c(y_grid[j],y_grid[j]), z = c(min(z_grid), max(z_grid)),colkey = FALSE,add=TRUE)}}
for(i in 1:length(x_grid)){
for(j in 1:length(z_grid)){
lines3D(x = c(x_grid[i],x_grid[i]), y = c(min(y_grid), max(y_grid)), z = c(z_grid[j],z_grid[j]),colkey = FALSE,add=TRUE)}}
plotrgl(new = TRUE)
