Mars Lenticular Picture Frame - Mona Lisa Versión 002

Mars Lenticular Picture Frame Instructions
-------------------------------------------------

This mesh picture frame has two lenticular surfaces each of 512 strips (256 in each direction), one forward facing the other behind a background surface.

When it is viewed from 45 deg once image appears and as you cam around to the other 45 deg point it morphs into the other image.

Face descriptions:

0 - Back & sides of frame
1 - Front view from the right
2 - Front view from the left
3 - Back view from right
4 - Back view from left
5 - Front of frame
6 - double sided background to assist with semi transparent images on the lenticular surfaces

The lamp may be unlinked and removed leaving a 1 prim land impact mesh.when (2m x 3m).
Any images may be applied to the lenticular surfaces. The Mona Lisa example uses one image which is split into 3x3 hence the reason why the horizontal & vertical scales are 0.33333. You may change the images or simply select a different Mona Lisa image by adjusting the horizontal & vertical offsets (-0.33333, 0.0 or +0.33333).
Of course for separate full size images set horiz/vert scale = 1 and both offsets 0.

Advanced
------------
Making the frame itself transparent (faces 0 & 5) will allow you to set reverse images on the back lenticular surface (faces 3 & 4).

Note it can be fiddly selecting these faces (make sure your camera constraints are off & you cam in close or you can use a disabled script in the frame)
