Hello all.

I am getting back into animation after a couple of years break, and I would 
like some help with creating a moving television or picture animation within 
an animation.

(details).  I have a pre recorded video of some students of my karate club 
at a tournament, and I would like to include some footage of them in an 
animation created with Moray & PovRay.

Is there a tutorial anywhere that could help me.
I have found animations on the PovRay site where this is done, but have no 
idea how to achieve this.

Thanks Alex.

Hi.  First of all, I should mention that I'm not a Moray user...

When you did animations in the past were you doing the animating portion in
Moray or in Pov-Ray?  If you're already used to converting numbers &
associating segments of animation in Pov-Ray with different values of clock
or frame_number it's a good start.

If you've got some software which can convert your video into a sequence of
numbered files (similar to what Pov-Ray outputs in animation mode) then
with some string-manipulation you should be able to read in individual
frames of video and slap them onto your 3d model using image_map (3.5.1.5.1
 in docs).

What format is the video in? Maybe somebody will have a suggestion for
turning the video into individual frames....

Hope this helps some

Charles

I used both in the past, Moray for quick tests to see that it comes out as 
it should, then PovRay for the final movie.

At the moment the video is still on 8mm Digital tape, my video software, 
Pinnacle Studio 9 is capable of saving in multiple formats.
I was hoping not to go down the road of having to save the video as 
individual images, hoping to find a patch or shortcut that would allow a 
video to be taken frame by frame directly off the video file, but if there 
is none, then that is the way I will have to go.

The reason being that I wanted to have a number of movies within movies 
going at the same time, as in a series of screens with video images going 
on, and the camera dollies past each one.
There will be a large number of images for 4 or 5 files.

Thanks anyway.

Alex.

post it in p.b.i as UV Mapped Cylinder - Map01a.avi but it has disappeared.
The only way I know how to do it is as Charles says, extract the frames and
use them as image maps on your TV screen.
Even though this uses a lot of disc space it does have the advantage of
knowing what will be showing on the screen at each stage of your animation.

Well, there is another (more CPU and disk-space intensive) way...a while 
back I experimented with DF3s, building a block where each slice is a 
frame of an animation, then translating the texture through a container 
which only shows one slice at a time, and having the media of the 
density map set to be either emitting (for a CRT) or absorbing (for a 
filmstrip)...

I remember that! You should have posted a link.
Did you ever get it to display in colour?

I couldn't find it T_T

Yes, by way of making three separate DF3s, one each for red, green, and 
blue, then stacking the containing boxes (if they exactly line up they 
have coincident surface issues).

I did something similar about the same time using three df3's I made from the
"Invisible Orchard's" Cubic Mandelbrot code. Only I used one containing box with
a material that had three emitting medias in the interior. Each media used its
own df3 file. I have just tried to reproduce it using a photo and extracting the
R,G and B channels to no avail. I can't get an image, drat! I can't find my
original scene as I did it two system crashes ago :-(

I've done it here, for testing:

Large BMP with four frames... And sliding on X...
