IMAGE DESCRIPTION: 
    A view on the Halong bay, early in the morning.


DESCRIPTION OF HOW THIS IMAGE WAS CREATED: 
    One Height field for the montains
with rotation and scaling to appear with different shapes at the camera
location. The height field was created with a POV script 'reliefhalong' (an
agate pigment with a spot light)
The vegetation on the left is an field of numerous bicubic patches
For the sky, I used a superposition of 3 pigment maps; one for the yellowish
sun, another for the clouds, and the third , non visible, for the upper part of
the sky, which make dark green reflects on the water.
The sampan is a bicubic patch and the net is made with torus and cylinders (It
was not possible to use a texture because it generates bad results with the
ground fog.
The man is just a flat polygon.
The water is a hightly reflective surface with small bumps, covered by a bozo
pigment map to realize the wind effects.
