As for the roll issue described below :
how hard would it be to implement something similar to
tr = Affine2D().scale(2, 1).rotate_deg(30)
inside mplot3D ? Where should I start ?
All I want basically is define my viewpoint with 6 parameters (elev, azim,
distance, roll, pitch and yaw), and not just 2 (elev,azim). I know it can
be done interactively, but I want(need) to script it.
Any suggestions ?

Hello,
I am using the scatter function and axes3D. I can define my viewpoint on
my data points using the elev and azim parameters. But I am looking for
more specification of the viewpoint : namely, I want to roll (i.e. rotate
around the view axis) and offset it (i.e. get sideways, not rotate around
my data points).Is there any way to do it ? At the moment, I am using transformation
matrices applied to my data points to reproduce the roll and offset.
Ultimately, I want to rotate and offset both the data points and axis, but
the transformation matrices only impact the data point.Hence my question : any way to roll and offset around a viewpoint with
Axes3D ? I don't want to do this interactively, I want to be able to
program it.Thanks, and cheers !
