You can also use this function I developed that's handy for checker-based
textures:
#declare smoothcheckerbasis = function (x,y,z,allfloors,xv,yv,zv) {
select(allfloors-floor(allfloors/2)*2,
0,
max(xv-.5,yv-.5,zv-.5, .5-xv,.5-yv,.5-zv),
min(xv+.5,yv+.5,zv+.5, 1.5-xv,1.5-yv,1.5-zv)
)
}
#declare smoothchecker = function (x,y,z) {
smoothcheckerbasis(x,y,z,floor(x)+floor(y)+floor(z),x-floor(x),y-floor(y),z-
floor(z))
}
Use it like:
function {smoothchecker(x,y+.5,z)}
(translated by .5 units to show the interesting part on the X-Z plane)

Are photons available in the released versions of POV?

Nice! Reminded me of one I'd done a while back. Same effect where the photos
sear the phosphorus off your screen. I like the textured checkered tile
underneath and the nicely rounded edges on the ring.

Ooops, I meant to type "...the focused photons..."

slope_map is also in 3.1, so I guess what Warp wrote would work okay minus
the noise_generator 2 part.

Not yet in a final release. Only the 3.5 beta, MegaPOV and perhaps some
other custom compilations.
