This starts to sound a bit like those countries where the use of software
such as SSH as prohibited because it uses high-level encrypting (which the
government is unable to crack).

Agreed.  The lengths that the Americans are prepared to go to protect 
absolute copyright are bringing them perilously close to a police state.

American legislators must be looking enviously at such admirable countries 
as China, Belarus, Pakistan and Singapore as their legislation is certainly 
bringing the United States much closer to autocracy than democracy.

To be fair, it's not "the people" who are asking for draconian copyright
protection, it's the companies. Being an American, I'm rather disgusted
at the direction the country is going.

    We are all outlaws in the eyes of America.

    I knew those old slogans would come back into use one day... I am glad I
saved them.

I think most Americans are guilty through inaction.  These kind of bills 
only get tabled because there aren't millions of people demonstrating to 
_demand_ campaign finance reform and legislative accountability. 

Give to the EFF and ACLU.  Write to your unelected president and 
representatives to *demand* campaign finance reform.  In twenty-five years 
you and your fellow citizens might make a difference.

What he said.  Much as I might not like him, Bush is the legally elected 
president of this once-fair nation.  Anyone who says otherwise is just trying
to make trouble.  Even Gore gave up on flaggellating that particular deceased
equine.

By the way, when a bill gets "tabled" here, it's effectively dead.  Another 
one of those leftpondian-vs.-rightpondian things.

Actually, when I first saw this thread subject, I thought they were talking
about modelling actual watermarks with POV...

...

*cough*

While not exactly something one encounters every day, it would be kinda
neat to do one.  Make a semitransparent piece of a texture map?

Oh yeah, that's something else...shouldn't an object (other than a plane
which doesn't exist in realspace) with any given material become transparent
as its thickness decreases to micrometres?

*wanders off aimlessly*

The sad thing is that SSSCA only makes life more difficult for the average
consumer, not for the big "professional" copyright breakers.

You can achieve this quite simply if you set the texture of your
object transparent (fully or partially, however appropriate) and then
set the interior's fade_power and fade_distance, the latter one
probably very low in comparison to the thickness of the object, if
you want to simulate usually-non-transparent materials (such as wood
or stained plastic). Glass or similar stuff should of course get a
quite high fade_distance with at least the order of magnitude of the
thickness of little objects, since it should only be non-transparent
when it is extremely thick.


Regards,
