well, use plain trigonometry..

p2
.
.
. a
p1

TAN a = (p2.y - p1.y) / (p2.x - p1.x);

so, a is ATAN(TAN(a)) ...

This is only in 2 dims

Use the above code, but replace y with z...this gets the rotation on the y axis

then if you´re a little smart and so on, you can replace x with y, and you´ve got the x rotation

"then if you´re a little smart and so on, you can replace x with y, and you´ve got the x rotation"

If you got a brain you will understand that it is not working that way! Think next time and reply then....

What do you think we have trigonometry at school??? Right, to LEARN these things

Just get a piece of paper and figure out the formula...

I figured out the line-plane intersection formula all by myself in half-an-hour

ooooooooh! If you are so smart? Can you tell me what people use forums for? Not for insults. Think and maybe you can understand why you got banned from IRC.. and maybe you can understand why your replys dont help anyone...
