axes3d/bbox3d - axis values not fixed

Thank you!

Sorry, I have a couple more questions:
1) How to I turn off the box shading completely? I figured out how to
lighten it up to a grey color with col=c("white"...  . I looked in the
package pdf, but I didn't see anything.
2) I read about the zunit in the package pdf, but no matter what I change it
to it doesn't seem to change anything.

Here is where I am at right now:

x<- 1:10
y<- 1:10
z<- matrix(outer(x-5,y-5) + rnorm(100), 10, 10)
open3d()
persp3d(x, y, z, col="red",
alpha=0.7,aspect=c(1,1,1),xlab='',ylab='',zlab='z', axes=F)
bbox3d(xat=c(5, 6), xlab=c("a", "b"), yat=c(2,4,6), zunit=10,
col=c("white","black"))

Thank you for your help!

Hello,

I'm using the rgl package and plotting a plot with it. I'd like to have

all

the axes values auto-hide, but I want to plot a series of characters

instead

of the values of the measurement for 2 of the axes. So in the end I will
have one axis (z actually) behave per normal (auto-hide) and I'd like the
other two axes to be custom character vectors that auto-hide.

The axes in rgl are a little messy.  It's been on my todo list for a long
time to fix them, but there are a lot of details to handle, and only so much
time.

Essentially there are two separate systems for axes:  the "bbox3d" system,
and the "axis3d" system.  The former is the ones that appear and disappear,
the latter is really just lines and text added to the plot.

Example:
x<- 1:10
y<- 1:10
z<- matrix(outer(x-5,y-5) + rnorm(100), 10, 10)
open3d()
persp3d(x, y, z, col="red", alpha=0.7,
aspect=c(1,1,0.5),xlab='',**ylab='',zlab='', axes=F)

For the above, axes=F for demonstration purposes only. Now when I call:
axes3d()
...the axis values hide/behave the way I want, but I want my own

characters

in there instead of the values that default.

You want to use the bbox3d() call.  For example,

bbox3d(xat=c(5, 10), xlab=c("V", "X"), yat=c(2,4,6), zunit=10)

for three different types of labels on the three axes.  It would be nice if
axis3d had the same options as bbox3d, but so far it doesn't.

Trying again:
open3d()
persp3d(x, y, z, col="red", alpha=0.7,
aspect=c(1,1,0.5),xlab='',**ylab='',zlab='', axes=F)
axis3d('x',labels='test')
...puts in a custom character label 'test', but I loose the

behavior/hiding.

Also, then how do I get the values for the z axis to populate with the
default values and auto-hide with the other two custom string axes
auto-hiding?

I'm pretty sure I need to use bbox3d(), but I'm not having any luck.

I'm new'ish to R and very new to the rgl package. Hopefully that makes
sense.

Thanks for your help!
