RENDER TIME: About 6-7 Hours
HARDWARE USED: 
 K-6 400Mhz with 128 Mb Ram "under" Windows 98 for develop the 95% of the scene code and a
 Pentium IV 2.4 Ghz with 1Gb Ram "over" Windows XP for final tests and render 

IMAGE DESCRIPTION:

DESCRIPTION OF HOW THIS IMAGE WAS CREATED:

 Terrain
 Is was done following the Neil Korban's tutorial "Drop on a Surface", available in  
 http://www.wikipov.org/ow.asp?DropOnSurface,  but instead of place randomly objects
 on the surface, the objects were arranged inside a double #while-loop. The Ground is a 
 height_field object created with Photoshop's plugin Render Clouds, and a slightly customized 
 paintbrush tool to draw the cracks.

 Floor tiles 
 In the final version are isosurfaces generated from a example code included in pov-ray.  
 They were placed in the scene by two macros, one to place sufficient floor tiles to cover all 
 the scene over height_field on the ground, and other to scatter a few floor tiles on the previous 
 macro.
 
 Water
 This object is another height_field created in photoshop to simulate the ondulations on the water 
 and that was scaled to cover all the scene.

 Trees
 They are located outside the direct field of vision of the camera. They were created using the 
 macro Arbre.inc of Steven Pigeon.

 Leaves
 Leaves were created from the leaves that came with arbre.inc, but modified to include a certain 
 random component in the form and the color. They were located in the same way that the random 
 floor tiles.
 Birds 
 CSG Union of sphere_sweeps and spheres scaled and rotated randomly to appear the movement of the wings.
 They were placed to fit his position where they were reflected in the water.
 
 Fence 
 CSG Union of cylinders using a simple #while loop.

 Cat
 Is a character from Poser 4 imported with Poseray and texturized with the Furtex 
 macro of Rune Johansenn.

 Golden Ratio
 The floor tiles and the image file have a proportion of 1 by 1.618, also well-known like golden ratio 
 or divine proportion, one old natural relation present in many alive beings between a part and the whole.

 Final adjustments 
 the final image was adjusted in brightness and contrast, and added signature and URL with photoshop 5.5

 Terreno
 Se hizo siguiendo el tutorial de Neil Korban "Drop on a Surface", disponible en
 http://www.wikipov.org/ow.asp?DropOnSurface, pero en lugar de colocar los objetos aleatoriamente 
 sobre la superficie, se dispusieron mediante un doble bucle anidado para formar las hileras y las
 colummnas. La superficie es un objecto height_field creado en photoshop mediante el filtro Nubes y
 una levemente modificada brocha para situar las grietas sobre el terreno.
 
 Baldosas
 En la versión final son isosuperficies generadas a partir de un código de ejemplo encontrado en los
 ficheros de demostración de pov-ray. Se situaron en la imágen mediante dos macros, una para situar 
 suficientes baldosas para cubrir toda la escena sobre el height_field del suelo, y otra para esparcir
 unas cuantas baldosas sobre la macro anterior y figurar que habian sido arrancadas del mismo suelo.
 
 Agua
 Es otro objeto height_field creado en photoshop para simular las ondulaciones sobre el agua y que cubre 
 toda la escena.

 Árboles
 Son 3, situados fuera del campo de visión directo de la cámara. Fueron creados utilizando la macro 
 Arbre.inc de Steven Pigeon.

 Hojas
 Fueron creadas a partir de las hojas que venían con arbre.inc, pero modificadas para incluir un 
 cierto componente aleatorio en la forma y el color. Se situaron en la escena del mismo modo que las 
 baldosas aleatorias.

 Pájaros
 Union de sphere_sweeps y esferas escaladas y rotadas aleatoriamente para figurar el movimiento de las 
 alas. Se colocaron para ajustar su posición donde se viesen reflejados en el agua.

 Verja
 Unión CSG de cilindros usando un simple bucle #while. 

 Gato
 Es un personaje de Poser 4 importado mediante Poseray y texturizado con la macro Furtex de Rune Johansenn.

 Proporcion Aurea
 Las baldosas y el fichero de imágen tienen una proporción de 1 por 1.618, tambien conocida como la proporción
 áurea o divina proporción, una antigua relación natural presente en muchos seres vivos entre una parte y el todo.
 
 Ajustes finales
 La imágen final renderizada con pov-ray fue ajustada en brillo y contraste, y añadida la firma y url
 con photoshop 5.5
