STORY:

It was last summer, on a nice warm day in August. We were sitting in the garden,
enjoying our cola and red wine. Suddenly a few wasps, attracted to the sweet
cola attacked us. After they teased us a while, I managed to trap one of those
little creeps in the colaglass. Quickly we did leave the garden, hiding for the
other angry wasps.

The end of the story:
Of course, the wasp was set free, after he had looked at the nice beermat for a
while. So all animal lovers can set their mind at rest.




IMAGE DESCRIPTION: 


In case it isn't entirely clear:
A wooden table with a rusty parasol stake in it. The table has a wineglass and a
colaglass on top of it. The colaglass is covered with a POV-Ray beermat, to
trap one of the wasps. Off course, this covered glass is the fortress. The wasp
in it is prisoned and can't get out, while the other wasps can't get in.




DESCRIPTION OF HOW THIS IMAGE WAS CREATED: 

All models and textures in this scene I made myself. Description of how the
different objects in the scene are made:

- colaglass: Merge and difference of cones and torii. The liquid in it is
basically a cone. I used some CSG to create a meniscus and bubbles. Photons are
used for both the liquid and the glass. Maybe using media for the liquid would
have been better, because I'm not entirely satisfied with the result. But
unfortunately, time is up.
 
- beermat: A cylinder with slightly rounded edges. For the texture I made a
screen capture of the openingscreen of POV-Ray 3.1g for windows (the one with
the bucket of shells picture on it) and edited it in Photoshop. I used
CorelDRAW to draw the rest of the image map for the beermat. It has a wrinkles
normal.

- wasps: Modeled entirely in 3D Studio, most of the time with editable meshes.
The texture for the wings is based on the crackle pattern. The other textures
are based on image maps, made with photoshop. I used the MegaPov motion-blur
feature for the two flying wasps: the wings rotationd are passed in a sine
function to create more realistic results.

- table: Intersection of some rounded boxes and a cylinder. For the hole in the
middle of the table I used two cylinders and a torus. Texture is a two layer
texture. One layer has a wood pigment and normal. The other layer is a based on
a granite pattern (the dark red lines are created with this layer). 

- sky: blue skysphere. Gray-blue ground fog. A plane with layered texture, based
on the bozo pattern forms the clouds. My intention was to use clouds composed
of blob objects, filled with media, but they didn't make the final because they
need some more work.

- wineglass: a 3D Studio lathe object. In it are still a few drops of wine. I
used the MegaPov solid mesh feature to fit the wine in the glass.

- grass: Plane with a layered texture: The main layer has a granite normal, to
simulate the blades of grass. The second layer is a bozo pigment, to make the
grass darker here and there.

- fence: CSG of boxes. Has a simple wood pigment and normal.

- parasol stake: cylinder with a bozo patterned texture map. The white texture
is the paint, which is still on the stake and has a wrinkle normal. The gray
metal and the rust have a granite normal. The dark band on the stake is an
error, which I first saw in the final render. To bad, there was no time left to
fix it.

- lightsources: the main lightsource is a 4x3 area light, which shoots photons
at the colaglass an the liquid in it. A few simple lightsources are used to
create highlights on objects.

I suggest you do not look at the pov-sources, because they are very messy.
