Animating a Vector in three-dimensional space

Question

I have question about animation of vector coordinates in given x y z coordinate with time. So far I stuck at making output for each row if df and assemble them as a .gif . rgl vector diagrams: show right angles for orthogonal vectors

What I want to do it is closer to this Spherical Coordinate System video. But I dont need to the coordinate system to be rotated. Only vector rotation with time is enough for now.

Here is the example df for x , y , z vector

time <- seq(1,30,0.1)
x <- runif(291,-0.14,0.1)
y <- runif(291,-0.14,0.1)
z <-sort(runif(291,-0.9,0.9),decreasing=TRUE)

df <- data.frame(x,y,z,time)

library(matlib)
library(rgl)

vec <- rbind(diag(3), c(0.04,0.09,0.85))  # just for example.
rownames(vec) <- c("X", "Y", "Z", "J")
open3d()
vectors3d(vec, col=c(rep("black",3), "red"), lwd=2)

Answer 1

See the example in ?movie3d . The function there rotates the coordinate system, but it can do anything you want, including redrawing the whole scene.
