You had something like this in mind?

And yes, it's animatable to some extend.

What does the shadow do? I look forward to seeing your code when you 
tidy it up.

I think, the shadow should show the trick.


Best regards,

Nope, the shadow doesn't give anything away :)

Hi guys, yeah that's pretty much what I have in mind.
If you could send me some sort of code to study it that'd be great. I managed to
kind of tidy up the code in the first attempt that was posted in the other
thread, but the cylindrical cube is also amazing. I wouldn't really worry about
the shape though for the moment (even though having the code for this would be
greatly appreciated!)

Can I make a fixed time animation for a start?

There are two thoughts on this:

a) we can animate the light, this way seeing if the light position affects the
illusion (and to what extend)

b) we can animate the object by rotating the camera. This will also require to
move the difference objects accordingly along each axis of camera rotation.

Do you guys have any idea?

And One more thing:

I think that we do not need to have any surface or background. A black
background is always better for experiments like this and surely, it will not
reveal the illusion that easily.

Alex

Hi guys,

I figured a way to animate it for a fixed period, I put the line

rotate<0,-360*(clock+0.00),0>

in my pov object and then I created a .ini file with the following code inside:

; POV-Ray animation ini file
Antialias=Off
Antialias_Threshold=0.1
Antialias_Depth=2

Input_File_Name="transpAttempt1.pov"

Initial_Frame=1
Final_Frame=300
Initial_Clock=0
Final_Clock=1

Cyclic_Animation=on
Pause_when_Done=off

This rotates the object of course but the thing is that the "invisible" boxes
should move respectively. That's where I'm stuck at the moment.

Have you checked povray.binaries.animations?
Have you checked povray.text.scene-files?

This looks great, I will play around with the camera angle to see how this works
exactly,  there seems to be many things I need to study here.
But still, how am I achieving the animation with such a file? This is a pov file
after all, do I need to make an .ini file too?

Thanks,

Alex

This is true for all of us. :-)

No you can use toolbar command-line.
See help 1.4.2.2 Toolbar Command Line
