Ok, using the Sine and Cosine formula from this topic:
http://forum.thegamecreators.com/?m=forum_view&t=21323&b=7
I have a camera that rotates around the 'player' object when the user moves the mouse along the x axis.
What I would like to do now is combine two of the formula so that I can rotate around the player Y axis when the mouse is moved along the X (ie. left and right), and rotate around the X when the mouse is scrolled along the Y (up and down).

How can I go about combining these formula to create such a system? All methods I've tried create some weird zooming and spinning effects

Screw the rules...what can i blow up?

Doing the maths for an orbit with a changing plane of rotation hurts my head just thinking about it. This is how I would do it, avoiding any maths:

+ Code Snippet

sync on
make matrix 1,100,100,10,10
position matrix 1,-50,0,-50
make object cube 1,5
make object cube 2,1
hide object 2

do
turn object left 2,mousemovex()
pitch object up 2,mousemovey()
position camera object position x(2),object position y(2),object position z(2)
set camera to object orientation 2
move camera -20
point camera object position x(2),object position y(2),object position z(2)
sync
loop
