I am using FORM06r to create organic shapes, and I have no trouble
rendering single frames, but FORM can output a series of .inc files which
evolve the shape from one pre-defined shape to another.
    If these files were numbered SHAPE001.inc through to SHAPE100.inc, how
do I get POV to load the relevant file each time it renders a new frame in a
hundred frame anim?
    I guess it has something to do with strings, but I'm not sure exactly to
go about it.

Any help would be appreciated.

Thanks in advance,

Andy Cocker

Here's a possible way:

#switch (FC) //frame count FC=frame number
#range (0,9)
#declare INCF=concat(Frame_Folder, Frame_Name, "00", str(FC,0,0), ".", "inc")
#break
#range (10,99)
#declare INCF=concat(Frame_Folder, Frame_Name, "0", str(FC,0,0), ".", "inc")
#break
#range (100,999)
#declare INCF=concat(Frame_Folder, Frame_Name, str(FC,0,0), ".", "inc")
#break
#end

FC is the running count frame-wise, and Frame_Folder is path to file, 
Frame_Name is name of file.
Reason for the triple digit division done here is because P-R 3.0* for Windows 
would not accept a -1 in the str() function to pad zeroes ahead of the frame 
number. That might work elsewhere but I could not get mine to.
Maybe this will help you out.
