How's this for an iris? The colors may not be right, but otherwise... Oh...
sorry for the PNG, but JPG mussed the file up too much.
(POV-Ray 3.5b6 used, MegaPov shouldn't take much modifications, though)
#declare Fnc_IrisBase =
function
{
pattern
{
radial triangle_wave
scale 0.45 frequency 50
rotate x * 90
}
}
#declare Fnc_Iris =
function
{
mod(Fnc_IrisBase(x,y,z) + f_noise3d(x*100,y*100,z*100) * 0.5, 1)
}
#declare T_Iris =
texture
{
pigment
{
function { Fnc_Iris(x,y,z) }
color_map
{
[0.20 rgb <0.10, 0.30, 0.90>]
[0.85 rgb <0.12, 0.95, 0.70>]
[0.99 rgb <0.00, 0.05, 0.10>]
}
}
}
