coordinate systems in crystal space

[raq77]

Hello, somebody can explain me the coordinate systems used in crystal space? I have been reading that crystal space use left handled coordinate systems (axis +X rigth, axis +Y up and axis +Z into the screen), but I'm representing a particles system and it doesn't work as I hope. When I draw a particle in a certain position, it don't correspond with the position that it should.

I hope someone can help me. Thanks and excuse my bad english.

Raquel.

X->1 is to the right
Y->1 is above
Z->1 is in front of the camera

Ok, I have a room with dimensions (300,300,300). If I draw a particle in position (0,0,0) and I put the camera:
        GetView()->GetCamera ()->GetTransform ().SetOrigin(csVector3 (0, -150, 0));
        GetView()->GetCamera ()->GetTransform ().RotateThis (CS_VEC_TILT_DOWN, PI);
I can't see the particle. But if I put the camera:
       GetView()->GetCamera ()->GetTransform ().SetOrigin(csVector3 (0, -50, -250));
I cant see the particle perfectly.

Thanks.

Well isn't that normal? What is the problem exactly?

I need to have a vision of the scene from above (placing the camera up and down approach). 

Thanks

Nobody can tell me how can I do this? Perhaps, it's not explained well what I need to do?

Thanks. Raquel

Perhaps it is easier to use the csReversibleTransform.LookAt() method so that you can let your camera look at some specific point in the scene.
