If I have 3 angles of rotation for x, y and z, is it possible to construct a vector from thes using sin and cos. I need this for camera movement.

Just an advice: It might be a good idea for you to study some elementary linear algebra before you go on with your camera movement.

A rotation is a transformation that transforms one set of vectors to another. Thus, it is a relation between vectors, and in no way the same as a vector. Therefore it''s hard to understand what you mean when you say you want to construct a vector from a rotation.

Okay, i know that may have sounded a bit strange.
Heres what im trying to do in 2D.

     Y    V(don't know this)     |   /     |  /     | /     |/-----O-----X     |     |     |     | 

I know the angle XOV, and I need to work out V. I do this using sin and cos, that much works. I want to know how to do this in 3D. I've tried all this matrix stuff all weekend and could get it to work. I can move forward & backwards in XZ and look in all 6 directions, but can't move up r down in y.

hi
read about camera matrix > there are sins and coss of yours rotations

then multiply one-vector and this matrix

c''ya

Try starting here...

Rotation

Use the tags when doing ASCII art.<br><br>And yes, your problem can be solved. Look up spherical coordinates.<br><br>Cédric

Thanks for your help have it working now :-).
