The Moai
 
Story of Moais and Easter Island (http://mysteriousplaces.com/Easter_Island):

It is one of the most isolated islands in the world but 1200 years ago a double-hulled canoe filled with seafarers from a distant culture landed upon its shores. Over the centuries that followed a remarkable society developed in isolation on the island. For reasons still unknown they began carving giant statues out of volcanic rock. These monuments, known, as "moai" are some of the most incredible ancient relics ever discovered. The people of Easter Island called themselves the Rapa Nui.

The first westerners to discover the island wondered how any one could have survived on such a desolate, treeless place. Indeed, this was a mystery until recent core samples taken from the crater lakes showed that the island was heavily forested with a giant now-extinct palm while the Easter Island culture was active.

Apparently the islanders were greeted with a lush tropical paradise when they first discovered it. It must have seemed inexhaustible. The trees were cut for lumber for housing, wood for fires, and eventually for the rollers and lever-like devices used to move and erect the moai.
As the deforestation continued the moai building competition turned into an obsession. The quarry was producing moai at sizes that probably could never have been moved very far (one unfinished moai in the quarry is 70 feet tall!) And still the trees came down. With the loss of the forests, the land began to erode. The small amount of topsoil quickly washed into the sea. The crops began to fail and the clans turned on one another in a battle for the scarce resources. The symbols of the islanders' power and success, the moai, were toppled.

Eyes were smashed out of the moai and often rocks were placed where the statues neck would fall so it would decapitate the moai. The violence grew worse and worse. It was said that the victors would eat their dead enemies to gain strength, bones found on the island show evidence of this cannibalism. With the scarce food supplies it may have been a question of hunger as well as being ceremonial. A spooky cave (right) at the southwest corner of the island, Ana Kai Tangata, is translated to "cave where men are eaten." Inside are pictographs painted in ochre and white of ghost like birds flying upwards. With no wood left to build boats, all the Rapa Nui people could do was look enviously at the birds that sail effortless through the sky. The Rapa Nui culture and community, which had developed over the past 300 years, collapsed.

Their island was in shambles, and their villages and crops destroyed. There was no wood left on the island to build escape boats. The few survivors of the conflict, perhaps numbering as low as 750, began to pick up the pieces of their culture. One thing they left behind, however, were the moai.

A jewel of an island floating in an endless sea. A seemingly never-ending supply of raw materials. Technological advances. Population growth. Depletion of resources. War. Collapse. Sound familiar? The Easter Island story is a story for our times. We too are on an island floating on an endless sea. There are differences, of course. It could be said that Easter Island is tiny and that it was only a matter of time before the resources in such a closed system were used up. But there are parallels between the islanders' attitude towards their environment and our own, and this is the most frightening part of the story.

On an island as small as Easter, it was easy to see the effects of the deforestation as it was taking place. But the inhabitants continued their destructive actions. They probably prayed to their gods to replenish the land so they could continue to rape it, but the gods didn't answer. And still the trees came down. Whatever one did to alter that ecosystem, the results were reasonably predictable. One could stand on the summit and see almost every point on the island. The person who felled the last tree could see that it was the last tree. Nonetheless, he (or she) still felled it.* This is the really scary part. As our own forests fall to the bulldozers, there are many who are valiantly trying to save them. It is obvious, now that we have satellites showing us the massive deforestation, that there is a serious problem. And yet our leaders  and even the majority of individuals  look on, unconcerned. They appear willing to bulldoze the last trees to build the moai of our time  technology & development. Will we have the sense to reconcile our lifestyles with the well-being of our environment, or is the human personality always the same  as that of the person who felled the last tree?

Inspiration:

My Inspiration was to build a scene that looks peaceful even though that may not be true. I found that a landscape with water, birds, boats, and tree should look peaceful enough, but to give this little touch of ancient culture I added a moai which gives some magic element to the scene.

Problems and Solutions:

- When I start I decide to use tree from 3D Café, but the render time increase a lot, then I decided to do my own trees with a tutorial that I found on www.geocities.com/CollegePark/9315/lw/tip6.htm.

- Other problem was how to make a landscape with out expending a lot of time. I found that by creating a one side box of 500 square meters with a subdivision of 100 segments on each one of the X and Z axis, and by triple them. That I could deform this object with an image map or alpha image that could give the bumps that I want on the landscape.

- Other problem that I had with the landscape was the texture, at the beginning I try to use the same texture that I used on my group project, but it didn't look well, then I create my own texture with Adobe Photoshop and it works well.

- Other problem with the landscape was that I have smooth bumps and I waned to recreate a more real surface, then I gave to the deformation a bump map that created this surface that I was hopping to have before.

- The surface of the water and its reflection was a little bit problematic because it took me some time playing with colors and reflections to obtain the right look, and with the techniques that I used for the landscape I finish the last touches for the water surface.

-With the Sail of the sail boat was a little bit similar problem but I create my own textures for the sail and by applying the technique of deformation it gave the look of the wind passing around the sail
