I am looking for a routine to keep track of a dice, for instance, so I could tell what face,numbered 1-6 is face down.

Thanx for any help as always.

F.

I used a dice (cube) model and added an extra vertex to the center of each of the 6 faces.
Then (after the dice was thrown) I checked the extra vertix z-position.
The one with the highest position represents the upper face.

(-> vec_for_vertex)

you can also determine the number facing up from the pan/tilt/roll angles.

If you know which face is UP, then you know the one that is down.

DOWN = 7 - UP and conversly UP = 7 - DOWN
(on MOST 6 sided dice anyways, more statistically random)

Well obviously I know what the top face is, as I know what all the other faces are..... but I want the PROGRAM to know what face it is!!!!!
Thats the problem.....

Quadraxas and mercuryus told you how to do it...

Darkmatters, first state your problem propperly
(eg, using physics, using just a normal model with random numbers etc) and
in which part you cant progress,
before asking people to write and test sourcecode for you.

or..dont make a dicegame if you cant even handle such trivial
tasks.

Firtly, I DID state the problem, also, I am NOT asking anyone to write source code for me, just a pointer would do, thirdly, its not a dice game, that was used purely as a descriptive itemisation of the problem at hand.

I have used the methods Quadraxas and mercuryus suggested, but they dont return the parameters required.

Thought you guys liked a challenge, I know I do.....

I do not know how can we give more pointers without writing the code.

this is no challenge. it's a very small task that i am sure posters above you can write the code for that in minutes.

"but they dont return the parameters required" , then you did it wrong. Can you please show us how did you tried the methods?

And you don't give a single description of the way you did it.

To get help, you have to describe what you already tried, in detail, not an 'I already tried that', because that isn't sufficient.

There is no challenge to someone in writing something that he has already written. It is only boring unpaid work, then. That's it.(I can assure you that the thing with the applied vertices that you test with vec_for_vertex works like charm.)
