"Rotation of a picture (transformed to a cylinder) around its own axis"

Hi,

I want to rotate the cylinder this way: youtube.com....

I had to rotate the picture layer which I transformed to a cylinder with the second slider to 90 degrees. (Then the camera looks straight through the cylinder, as shown in the YouTube link.) If I try to rotate the cylinder then, the first and the third sliders act in the same way, there is no difference whether I use the first or the third slider to rotate the object around the z-axis. But usually, one of the two sliders should rotate the cylinder around the y-axis. Even if I change the ROTATION CENTRE property, I don't get the wished effect. What can I do?

Here's a file: speedy.sh....

Thank you very much in advance.

John

I think I would place the TARDIS inside a container layer.

I would animate the 2nd slider of the ROTATION property of the model layer to make it rotate around its vertical axis.

And I would set the ROTATION CENTRE of the container layer to about (0,-100,0) and animate the 3rd slider of the ROTATION property.

Splitting it in 2 separate rotations (the model layer and the container layer) makes it easier to create complex rotations.

Hi Michiel,

the rotation of the TARDIS is no problem for me.
My problem is the missing rotation of the wall texture that is transformed to a cylinder. I would like to animate this layer to rotate around its own axis.

Here's a description of what I want: postimg.org....

Thank you very much :).

Rotate te cylinder with the 1st slider of the ROTATION property.

Place the cylinder inside a container and set the ROTATION property of the container to (0,90,0)

Hi Michiel,

thank you very much! This works fine.
But why is it so complicated? Here is a link to a video in which I explain how it works in Blender without any container layer: videobam.com...

I am very confused why there is such a huge difference between these two programs. Is there a specific reason? I'm really interested in understanding this different behaviour of the softwares.

Prachtige dag en veel dank

It's about the order of the angles (heading, pitch, roll) and the way the cylinder is defined. No matter which choice you make, there will always be an impossible rotation.

If you don't like containers you could position and rotation the camera so it lines up with your cylinder.

Okay. Thank you very much, Michiel!

I'll keep this trick in mind.

Nog mooie avond en vriendelijke groeten
