Hello,

I have a little rectangle which I like to rotate / animate. The rotation should give a kind of 3D impression -> the backward going part is shrinking and the forward comming is growing relative to the middle axis which goes noth / south.
I checked the GIMP help and asked google but I did not find a way to do this under linux with GIMP, just some expensive MS Windows solutions. Any hint how to do this are very wellcome. :-)

I hope this is not too bad expained, my English leaves room for improvement - which I am working on.

Thanks a lot Michael

Hello Jeff,

thanks a lot - I am not sure if I got all. Will try soon. I have a German GIMP 2.2
and I am not sure what mad Object in the filter Menu can be no seem me right..
the filter menu is spilt in 5 parts, which of these is it? And will this be selfe explaining : "you'll need a bunch of layers (one > for each frame), and you are
mapping your image to the 3d object" when I come to the right place? I am not sure if i understand, at
this point in time, what you mean - that mighht change when I find the correct menu.

THanks again
Michael

I used to do this all the time with

Filter -> Map Object

Select box, you can rotate it at will, you'll need a bunch of layers

(one

for each frame), and you are mapping your image to the 3d object, so

make

sure it is something interesting (I just tested again with a simple pure

red

image, looked great as it span.

Hello Oliver,

great this is exactly that what I was looking for. To get a smooth rotation how many frames do I need to create? For a 360 turn via the y-axis?
After I have these many frames how do I get the animation? At the bottomline I like to get a gif file or what every is ok to be placed on a web page.

Thanks a lot again for the great help. Michael

2- A better choice would be the "Map Object..." plugin, in Filter->Map set the following settings (do not change the ones I do not mention): check "show preview wireframe"
Option tab:
Map to: plane
check "transparent background"
Light tab:
Lightsource type: no light
Orientation tab:
use the "Rotation" Z: änd set it to the angle you want

You will have to create first many copies of the image you want to spin first, and then apply the effect with different angles to each one. See the following tutorial for some similar effect: http://www.home.unix-ag.org/simon/gimp/globes.html

Best regards,

Olivier.

Hello Oliver,

I did some testing and got a great result !!! Thanks a lot. Perfect!

One final question: what size, colour depth and how many dpi is a good choice for a logo in the internet.
Mine is a little too big.

Thanks a lot, again Michael

It depends on the speed you want. 10 frames per second is usually enough

(25-30 is video setting). You will have to try. Start with rotating every 20 or 30°.

After I have these many frames how do I get the animation? At the bottomline I like to get a gif file or what every is ok to be placed

a web page.

There are again 2 solutions. The GAP (gimp animation package) is very useful in the long term, but requires some time to learn it. There are some animation tutorials there:
http://www.gimp.org/tutorials/

The "good old way" is perfect for animations with few frames See tutorials there:
http://gug.sunsite.dk/tutorials/biggyp1 (only do the three last steps, from the moment it says "Now you can set the layer timings")
or even better:
http://gimp-savvy.com/BOOK/index.html?node80.html

Best regards,

Olivier
