Hello Guys,
I am currently trying to use Pov to make a virtual box, My troube comes
with the "image_map" functionality .
I'd like to map some GIF's on each face of that box, it works very fine
with the cover and the back of the object, but when I try to apply it
on the sides, the top and the bottom, It fails each time, I mean POV
tries to map the GIF's but it only takes a bit of it so Only a little
part of the GIF is displayed on the box, II defined my SCALE and
TRANSLATE in the same state of mind as for the cover and the back, but i
don't know why it does NOT work :(
Well, PLEASE, HAVE A LOOK AT MY SCRIPT BELOW, THANKS A LOT, I've been
reading the the Manual for a bunch of days, I tried to find some
examples on the web, everything seems allright, but I am still at the
same situation.
I thought that you guys maybe encoutered that kinda trouble and prolly
know how to fix it,
Regards,
Here is a copy of my POV SOURCE :

A planar image_map is by default projected on the XY plane, going from x=0; y=0
to x=1; y=1
In order to apply it to a surface facing up or to the side, you have rotate it
accordingly (or create the object along the XY plane, apply the texture and then
rotate the object in place).
Here's a skeleton example; I'll use polygons for the faces of the box:
#declare Tex=
texture{image_map... translate <-0.5,-0.5,0> scale 2}
//The transformation is there to align the image with the face
#declare Face=
polygon{4, <-1,-1,-1>, <-1,1,-1>, <1,1,-1>, <1,-1,-1>}
union{
object{Face texture{Tex}}
object{Face texture{Tex} rotate y*90}
object{Face texture{Tex} rotate y*-90}
object{Face texture{Tex} rotate x*90}
object{Face texture{Tex} rotate x*-90}
object{Face texture{Tex} rotate x*180}
}
