您可以使用 #Data example
Nominal_City_Name = c(0.7,0.2,0.5)
X = Nominal_City_Name[1]
Y = Nominal_City_Name[2]
Z = Nominal_City_Name[3]
#Bring in RGL library
library(rgl)
#Contributor cuttlefish44's code
c3d <- cube3d(color="grey", alpha=0.1)
c3d2 <- c3d %>%
translate3d(1, 1, 1) %>%
scale3d(0.5, 0.5, 0.5)
c3d3 <- cube3d(color = "blue", alpha = (0.5)) %>%
translate3d(1, 1, 1) %>%
scale3d(0.5, 0.5, 0.5) %>%
scale3d(X, Z, Y)
shade3d(c3d2)
shade3d(c3d3)
axes3d()
# Add points at vertices
points3d(t(c3d3$vb), size = 5)
# Add lines to edges of box
for (i in 1:6) lines3d(t(c3d3$vb)[c3d3$ib[,i],])
#------------Add labels/title to 3d window-------
# This version of title (commented out) doesn't work as well as the
# bgplot3d() version now included in output section below.
# Use this title3d() version if you want the title to be dynamic to
# the graphic.
#Title_XYZ = paste0(stakeholder," ","X, Y, Z")
#title3d(main =Title_XYZ,cex = 2, line = 2)
mtext3d("X Var",edge="x-+",line=2,las=2,cex=2,srt = 50,col =
"darkorange3")
mtext3d("Y Var",edge="z+-",line=2.5,las=2,cex=2, col =
"chartreuse4", srt = 90)
mtext3d("Z Var",edge="y-+",line=3,las=2,cex=2, col =
"darkblue")
#
#-------Create output file-------
#This section first sets the window view parameters and window size
# to what I want it to be. Then it exports to a location you choose.
# After dynamically moving it to look the way you want in 3d view -
# Use par3d() to get view attributes (i.e., windowRect (window size)
# info), among other measurements. Theta, phi, fov, and zoom give
# angles, field of vision, and zoom.
rgl.viewpoint(theta = 45, phi = 4, fov = 60, zoom = 1)
window_size = c(164,32,1259,1050)
par3d(windowRect = window_size)
#Adding title using a background plot. This must be done AFTER
#resizing the window, because it doesn't scale gracefully.
Title_XYZ = "This is your title"
bgplot3d(
plot.new() +
title(main = Title_XYZ, line = -10,cex.main=3))
#a = folder, b = stakeholder name, c = file extension, d = concat of
#all 3 for export
# a = "C:\\Users\\MyUserName\\Documents\\R\\export"
# b = Title_XYZ
# c=".jpg"
# d = paste0(a,b,c)
# rgl.snapshot(d)
侦听器获取新目标Vertex
像这样：
mxEvent.CONNECT
