Ciao Christian,

Don't worry about the delay,
as you can see, also I am not on time!
In this period in Italy there are a lot of holiday (25/4, 1/5)
and the other days I've worked in a military company, 
where I cannot connect to the Internet.

You are right about my aproximate explanation,
I wrote those while I was making other five things, so I haven't
double checked what I have written....

All your objections are right.

Probably you are little less rusted than me with trigonometrical calculations.

But, apart my errors, I think that the important thing was that 
you have understood very well what I had in mind.

I am in agreement with you on specify angles in degrees,
and set the value of k to "2".

Yes, you are on right about patch rotation that isn't very simple
to use...I will try to think something else.

About the slides, I think that these are used to represent just
2D drawing, so thetax e thetay should be not influential, and only "angle"
works to permit to rotate patches (in a more simple way than 3D patches...)
I'm perplexed about using normalized coordinates on slides, 
because are typical of 3D space, and I don't known if they could be
useful on slide...you could permits the use of normalized coords 
just only on cubic panoramas.

About patches, 
I've notice that if you place a patch across two faces, or better,
you place a patch that goes beyond the edge of the face
(i.e. face is 640x640, and you put a patch 100x100 at x=600)
the part of the patch that fall in another face is cut in a 
randomly way, and it varies based on the azimuth angle of the view.

Is this an intentional behavior? 
Or it would not be better crop the part of the patch 
that it exceeds the edge of the face?

If I put a lot of patches (beyond 800), I've notice, in slower computer,
that the rotation around the azimuth angle, sometime it goes in jerks.

You think that I could reduce jerks if I reduce the dimensions (in bytes)
of the patches? Or 800 patches is really too-many patches?  

Thank you.

Ciao.

Andrea

P.S.: There are a lot of spams on your wiki pages...you can see if you
click on "recent changes"
You have to think some way to prevent these abuses...
