Customizing Animated and 3D Plots using RGL Package
The RGL Package in R also provides us with various functionalities to customize our 3D plots. We can change the size, color, and shape of the points plotted on the graph, as well as add a bounding box to it. Let us see a couple of examples to customize the plots.
Adding axis lines
In this example, we customized out the plot by adding a background color to it using the bg3d() function. We also used the Points3d() function to plot the points on the graph and the lines3d() function to add x, y, and z-axis lines and provide them with different colors. Lastly, we added an animation to the graph using the play3d() function which rotates the graph on the x-axis.
R
# import rgl package library("rgl") # load the dataset data(iris) # define background color bg3d(color = "grey") # plot the points points3d(iris$Sepal.Length, iris$Sepal.Width, iris$Petal.Length, col ="black") # define the axis lines lines3d(c(min(iris$Sepal.Length), max(iris$Sepal.Length)), c(0,0), c(0,0), col = "green") lines3d(c(0,0), c(min(iris$Sepal.Width), max(iris$Sepal.Width)), c(0,0), col = "blue") lines3d(c(0,0), c(0,0), c(min(iris$Petal.Length), max(iris$Petal.Length)), col = "yellow") # add animation play3d(spin3d(axis = c(1, 0, 0)), duration = 10) |
Output:
Adding axis to 3D plot
Adding Bounding Box
In this example, we plot the lines instead of points or spheres using the plot3d() function with the type argument as ‘l’ which indicates lines. The bbox() function is used to add the bounding box to the graph and we provided the col to blue as the arguments which will be the color of our bounding box.
R
# loading RGL Package library("rgl") # loading iris dataset data(iris) # adding background color bg3d(color = "lightgreen") # ploting lines plot3d(iris$Sepal.Length, iris$Sepal.Width, iris$Petal.Length, col ="yellow", type = "l") # adding bounding box bbox3d(col = "blue") #adding animations play3d(spin3d(axis = c(0, 1, 0)), duration = 10) |
Output:
Bounding Box 3D graph
