I am a new user for povray. hope to use this tool to visualize my simulation
results. My system includes one atomic cluster in a fluid composed of
multiple single-atom molecules.
To view the structure, I wish to use the "transparent" function of povray to
show the liquid molecules. It turns out that this works on my PC, but this
function completely disappears when I transferred the same code to the Linux
system.
Is there such a function for Linux system, or just something is missing in
the INI file? Can anyone give me a clue on this?
Also, the transparent function does not work perfectly on PC: for no-overlap
case, it is perfect. However, when there are overlaps b/n liquid particles,
the color becoms non-realistically darker. This is not required. Anyway to
solve this problem to achieve the effect of a stone in water ?
What I used is specifying the color of each liquid particle by "rgbt
(0,1,0,0.9)"
Thanks,
Jie

Which transparency function are you talking about in detail? Transparent
textures, alpha-channel in images or transparency in the final output?
Normally there are no differences between the different version of POV
(Linux/Windows/Mac), so could you perhaps post some code which shows
that behaviour? (There used to be a difference in fresnel reflection,
dunno if it's still there in 3.6).
HTH,

Given just this info, my hunch is that if you wrap the overlapping
particles with a "merge { }" the color difference may disappear.
