Ok, it's a vector, so ... it has a line of action ... this goes through the middle point of the camera, right? ... it has a direction ... is it like "sending an arrow towards the camera" or "sending an arrow, that shows in the same direction as the camera"? ... what does the value of the components of this up vector mean to the camera? ... like (1,0,0) or (100,0,0) ... 1 or 100 does it change something? ... thanks again ...

EDIT: I'm playing with the sliders, but I can't figure out, why the camera how moves or where?!!! :D

How do I rotate the camera in the x,y-plane? ...

"The Up vector sorts out where the top of the viewport is located"

That's it? really? not more?!

when it's like this, then it can onle be vector one or vector 2?! ...

"That's what the Up is for on the Horster Version."
But this component is from Chameleon ... Does the up vector here has something with the rotation of the viewport also? ... I'm reading your answers twice and I save them also!!!!! :)

The camera up vector simply specifies the direction that is oriented up in the scene. What more did you want.

Think of like this. Look at a point on the floor. Chances are your eyes are parallel to the ceiling. So the Up Vector is Z or (0,0,1) where x, y and z are the three axes. Now tilt your head to the side, your eyes are no longer parallel to the ceiling so the Up vector has changed to (0,0.25, 0.75).

Did you download my new version SetView_mk2?

No I didn't yet ... But I will now ...
let's say I want to zoom out using this setcam component ...

The target point is (0,0,0) ... And I want to look at it from above ... so the z-axis goes through the camera and the camera is pointing downwords in the negative z-axis direction ...

Is it possible to zoom in and zoom out with this tool? ... I will download your SetView_mk2 right away ...

nice thing ... I guess I'm starting to understand how this works ... I haven't checked this with the up vector yet though...

beautiful man! ... But what's the script variable U in Setview? ... And what's the Up Vector in the setcam component? ... :D

About the up vector:

So if I give an up vector of (1,0,0) ... the x-axis just shows up?! hehe :D

EDIT: Just took time to understand ... Now I got how this works ... Love alll of you people!!!!!!!!!!!!

They are the same thing! UP = U

Ok, the problem is ... I'm looking at the xy-Plane from a point located above ... I'm looking from above in the negative z-direction ...

I'm trying to change the camera location to put the camera high above ... but it doesn't matter how large the number I put for the z-component of the point, that represents my camera location, the camera won't go up and it won't zoom out! ... is this normal?!

or this component is no good for zooming in and out?!

How to zoom in and out?! ... I'm trying this, but no clue, how!

EDIT: I thought, if you change the position of the camera, like put it up higer, you get the zoom out ... but this camera seems to be really very sharb!!!!!
