I would like to use pov to render a view like the
own drawn below for a box
+--+
/ /|
+--+ |
| | +
| |/
+--+
It's just the classical 3D technical drawing...
It looks like the orthographic camera, but
increase of the z is transformed as p*(x+y),
with p either 1/2, 1 or 3/4 ...
Have anybody any suggestion on how to achieve that ?
(with all pov-object, of course, not only the box).

This may be obvious to others as well, I can't make out your intention
exactly. I'd suggest posting a drawing if you could. I'd suggest
HTML formatted posting but that's NOT a good idea since people have a
difficult time with them. Also I flunked out of being a
"advanced-user" so I probably shouldn't even be here.

Hmm. I can't think of a simple way but _a_ way is to apply a shear
operation to each object at the origin and then translate into position.
Cheers, PoD.

Come on Bob, why don't we propose a group for the "disadvantaged user" or
something like that?

Something like this:
// Use -uv on commandline
#version 3.1;
global_settings {assumed_gamma 1.0}
light_source {<500, 500,-500>,1}
#declare Shear= transform {
matrix < 1, 0, 0,
0, 1, 0,
.5, 0, 1,
0, 0, 0 >
}
camera {
location <0.0, 0.5,-2.5>
look_at <0.0, 0.5, 0.0>
angle 65
transform Shear
}
box {
<-0.5,0,-0.5>,<0.5,1,0.5>
pigment {rgb 1}
}
