  Animation bug... (Message 1 to 6 of 6)  
From: Rarius
Subject: Animation bug...

Message: <478561e3@news.povray.org>
When rendering an animation using Beta24 (3.7.0.beta.24.msvc8-sse2.win32) it 
refuses to render the first frame if the Initial_Frame=0.

Ini file Example 1:
    Initial_Frame=0
    Final_Frame=359
    Initial_Clock=0
    Final_Clock=359
    Input_File_Name=earth.pov

Ini file Example 2:
    Initial_Frame=1
    Final_Frame=360
    Initial_Clock=1
    Final_Clock=360
    Input_File_Name=earth.pov

Example 1 creates frames earth001.png to earth359.png under Beta24 (359 
files)... Under WinPov3.6.1c it correctly renders frames earth000.png to 
earth359 (360 files)

Example 2 creates frames earth001.png to earth360.png under Beta24 (360 
files)...

Not a major problem in this instance, but I can see situations where it 
could cause major headaches.

Is no-one going to answer my report... even with a "We know about it, now go 
away!"?

Nope ;-) IIRC it was never documented to work in the first place...

I've penciled this in to look at later. If the behavior is different from 3.6
we may fix it.

I verified this behavior... here's a minimal test scene

// +kfi0 +kff2 +ki0 +kf2 +fn

// animation bug
// first frame may be skipped

// delete old renders first

#default{finish{ambient 1}}

#if (clock = 0)
// should produce "bug_anim0.png"
   sphere {0,1 pigment{rgb <0,1,0>}}
#else
   #declare check = pigment{image_map{png 
"e:\graphics\render\bug_anim0.png"}};
   sphere {0,1 pigment{rgb <0,1,0>}}
#end

This is fixed in beta 26. Please hammer the animation code for possible
side-effects to animations that use the default start frame number of 1.
