Hello,
I'm trying to figure out the Moray animation plugin and I've run up
against a few problems and was wondering if anyone had seen this before
and knows what's going on.
My problem is that when I create an animation with "X" (where X can be
any value) frames and set the FPS to "X" then render the animation, less
than "X" frames are actually produced, and the translations are
interpolated across those frames instead of the original values. The
funny thing is, when I do individual renders of frames by selecting the
desired frame in the keyframer then doing Render->render, the frame is
rendered correctly with the expected translation values. The above
doesn't really make sense, so here's an example of what I'm talking about.
1) I create a new scene with a single cube in it and assign it a solid
color.
2) In render->options I set the FPS to 24 via the drop down box, then
the start frame to 0 and the end frame to 23. I set the output format
to PNG (not that this makes a difference).
3) In the keyframer I set a linear translation from <0,0,0> at frame 0
to <23,0,0> at frame 23, and a linear rotation from <0,0,0> at frame 0
to <23,0,0> at frame 23.
4) Sliding the keyframer back and forth shows all interpolated values to
be correct between them, eg at frame 15 I have <15,0,0>, <15,0,0> for
translation and rotation. If I manually render frame 15, the correct
POV code is generated for this.
5) I save the scene and do render->animation.
6) Looking at the files produced, I only get 20 of them.
7) Looking at the code generated, the first frame has the correct
coordinates/rotation of <0,0,0>,<0,0,0>. But the second one has
<1.2,0,0>,<1.2,0,0> through to the last one which has
<22.8,0,0>,<22.7999999,0,0>.
What I want to do is produce an animation of one second, with 24 frames
moving linearly from A to B. Not an animation of 20 frames moving from
A to B via interpolated points.
What am I doing wrong?
Incidentally, is there any way within the generated POV code to know
which frame you're at? For example if I wanted to use the insertcode
plugin to "#include" a different file for each different frame, is there
a way for me to know what frame I'm at within the code?
Thanks,

You are doing nothing wrong, i think this is a problem within the
anim-plugin. However the source of it is not (yet) released, so no
bug-fixing :)

here's an excerpt from povray-help:
frame_number
If you rather want to define the action in POV-Ray animated scenes
depending upon the integer frame numbers, this identifier can be used.
It reads the number of the frame currently being rendered.
#if(frame_number=1)
//stuff for first image or frame
#end
#if(frame_number=2)
//stuff for second image or frame
#end
#if(frame_number=n)
//stuff for n th image or frame
#end

Ahh ok, thanks for the info. I did find a work around to the frames
problem. I found that if instead of selecting 24 FPS, if I select
"Custom frame rate" and then manually set 24 FPS in the input box, it
works the way it is supposed to, generating the correct number of frames
with the correct values for the interpolated fields.
Thanks again,
