[Plib-devel] ssg "Water" demo problem

[Jan R. <slo...@gm...>]

Hello,

I've posted this mail to the plib-users list about six weeks ago,
but got no reply. I'll repost it here and hope that someone can
reproduce or maybe even fix the problem:


I've noticed that there seems to be a problem with the
water demo in the plib examples pack. I can recall that using
the 1.8.1 examples and linking it against 1.8.3 worked fine.
Now I compiled the demos again, linking them with 1.8.4.
All ssg demos look fine except the water demo. It seems to
lack proper lighting. All objects are only dark shapes. Switching
to wireframe mode works fine, but there seems to be no lighting.
All "wires" are equally black.

I've tested this on my Linux machine (Debian, 2.6.10, NVidia
card and drivers) and on a WinXP machine (with some onboard
Intel graphics adapter).


I've recently tried to fix this on my own by playing around
with the position and colors of the light source, but this
didn't seem to change anything. Any ideas?

Kind regards,
Jan R.
