help with cube3d cube size
I'm using the command below on an open3d() object to create a shaded
cube. Changes to myScalingFactor do not effect changes in the size of
the cube. What is the correct approach? Mark
shade3d(translate3d(cube3d(identityMatrix() *
myScalingFactor),-6,1,-1),col="green", alpha = 0.2)

play3d() translation
Hi All,
I would like to be able to use play3d() to translate the view along a
surface, and zoom in and out. All the examples in play3d() function
description are of rotations.
I would also like to know if there is a method of creating a legend of for
the 3d surface using rgl package.
Thanks in advance.

drawing arrows with rgl
Hi,
I am looking for a package which allows me to draw arrows (cylinders
with cones on them, basically) in 3d images produced with rgl. Is such
a thing available?
I did notice the 'compositions' package, which contains
'arrow3D'. However, it relies on 'tensorA', which fails to install on
my machine with the error message copied below. If anyone can help me
fix this

3D package in R
Hi all,
I am considering writing a 3D visualisation package for R.
Purposes:
- Visualise 3 dimension data
- Manipulate the data or series or any other object with the mouse as in any 3D software (3D Studio Max, Lightwave...)
- Eventually display more than just 3D objects.
Justification:
- It's always interesting to plot data before performing any analysis
- Manipulating (rotating,
