IMAGE DESCRIPTION: 


It is magical that a caterpillar turns itself into a drab chrysalis where it
rearranges itself into a magnificent butterfly. We know what happens, we kind
of know how it happens but we have no idea why. It's all part of Mother
Nature's magic!


DESCRIPTION OF HOW THIS IMAGE WAS CREATED: 


The Butterfly veins were made using a modeler called Worms, where I drew them
free hand. Then, I sent them to CTD to make them into spheres and cones. I used
a radius of .5.
I gave the veins a black color and rendered them on a red background. Using PSP,
I used this render to create height fields for each of the three colors
(granite textures layered with a gradient) in the wings.
Back in Moray, I nested three very thin cubes, gave them their textures and
placed them in the center of the veins. Next, I differenced each of the height
fields with these cubes to create the shapes I wanted. I even used this to make
the holes so the white dots would show. I did one for the upper wing and
another for the lower wing. Then I copied and rotated them for the other two
wings.
The body is a lathed object with a spotted texture.
Then I positioned the butterfly and used some spotlights and it came to life.
The catipillar is a blob with some cones and toruses.
The chrysalis is a union of a lathe and a Bezier patch.
The flowers and leaves are CSG differences and/or unions of solid primitives.
All textures were created using Moray's texture editor.
