IMAGE DESCRIPTION: 

When I heard the topic of the IRTC would be "museum", I decided to build a
virtual museum for this wonderful artist Clarien van Harten. The room we are in
shows some of her impressionistic paintings. In the corridor there are a few
more or less realistic pencil-drawings: a portrait of me and part of a street 
somewhere in Denmark that she drew during a holiday.
And yes, she agrees with me using her works of art.


DESCRIPTION OF HOW THIS IMAGE WAS CREATED: 

This topic gave a very nice opportunity to have some practice on image-maps and
spotlights. The paintings are image-maps of Clarien's works. I first wrote a
macro to fit them into a frame. This macro was nested into another one, that
combines each painting with its own appropriate spotlight, pointing at the
center of the painting and with radius that matches the width of the painting.
For the "looks_like"-parameter I also wrote a macro to make sure that the tube
that contains the lamp points precisely at the center of each image. These
macros enabled me to experiment freely with positioning and moving both the
paintings and the rail with the spotlights as well as with varying falloff and
tightness of the spotlights.
The pigment of the walls and the ceiling is also an image-map of a part of one
of Clarien's paintings. The pigment of the floor is an image-map of a picture
that I made using Art-Matic. The textures of the wood for the frames and the
doorpost and of the brass rails are taken from POV-Ray's include-files
(Tan_Wood and Tinny_Brass).
I ended up with a rather nice picture but with an annoying patch of light
falling from the room into the corridor. I removed it by switching off the
light in the corridor and making the light in the room shadowless. Finally I
put two paintings at the sides of the picture to create the illusion that the
entire room is filled with paintings and not only the corner that is visible.

There are still problems with my ZIP-file. The sourcecode of my submission is
available on my webpage.
