As Mats pointed out, I forgot one line before...

IDL> flipIm = reverse(im, 2)

The following requires a 2D image, but it will do what you want. For 3D images, it would probably be easiest to use the Image() function.

cgLoadCT, 13
cgshade_surf, bytarr(227,149), indgen(227), indgen(149), SHADES=bytscl(dist(227,149)), ROTZ=60, ROTX=90, XSTYLE=5, YSTYLE=5, ZSTYLE=5
