According to section 6.3.4 Transform Identifiers of the documentation,
transformations can be invoked with or without brackets. However, when used
in cameras it doesn't work with brackets:
#declare T = transform {scale 2 translate 2*z}
sphere {0, 1 transform T }
sphere {0, 1 transform {T} }
camera {location 0 transform T }
camera {location 0 transform {T} }
I'm using POV-Ray 3.5 beta 1
on a P150, 16MB RAM
Windows 95 4.00.450 B IE 5 5.00.2919.6307

Should be easy to fix, though.

And, it's fixed. Thanks for pointing it out, Rune.

Thanks for fixing it.
How about the other camera transform bug?
Transformations that involve translations (including translations done using
matrices) are handled incorrectly.

I haven't looked too closely at that one yet. It might be a precision thing.

Okay, you're right. It's not a precision thing. It might be more
interesting to fix. The problem is that those transformations are
applied to four vectors: location, direction, up, and right. Of
those four vectors, only one is world-relative and should be
translated (though scale and rotate and presumably shear should apply
to all of them.)
That should be relatively easy to fix as well.

Okay, that one's fixed too. Thanks for pointing it out.
