Except its roof, this little house is completely made with parallelepipeds. Still, it would not have been very easy to put all its elements in place manually. And it would have been totally impossible to change its width, height and depth, or to modify the size of its windows; I did that a dozen times before I was satisfied with the proportions. The angles of the roof can be modified in a jiffy, too.

If your browser allows you to see that scene in wireframe mode, please notice that the sides of the parallelepipeds that cannot be seen simply do not exist: that is useful when you see the scene with a slow computer and very few RAM.

Each of the trees has a very simple structure: a cylinder, half of a sphere, and a cone, all that with only five sides to simulate the circular shape. As the basic shape is simple, it can be put many times without asking your browser too many efforts. Notice that the trees are put on a circle with a clearing at the center, that they do not touch each other although they have been put at random, and that their sizes and even their colors are slightly different. All that was done in seconds by a Basic program.

A good example of what you can do quickly with very simple shapes... if you ask a Basic program to do all the job of putting the elements in their correct position. The number of the columns, their size and the space between them can be modified easily.

The VR Cocha format does not use the red-green-blue logic that nobody except computers understands. Instead of that, it uses a hue-saturation-brightness logic that allows to define the color according to its position on the classic chromatic circle. Depending on your browser, you may or may not see bright yellows and dark blues, but the idea is that every rectangle on a same circle corresponds to the same grayscale (you can copy the screen and convert it in grayscale if you don't believe me).

One of the most interesting features in the VR Cocha format is to destroy the sides of a shape that are not supposed to be seen, to make the 3D files smaller and the work of your browser easier. This scene represents all the variants of a sphere you can get simply by changing the exclusion parameter in the VR Cocha format.

In wireframe mode, you'll see once again that the sides that cannot be seen simply do not exist. Apart from that, the Basic listing allows to modify quickly the colors, the proportions and the number of the side cones.

OK, I admit you could have done that manually. It was just an exercise to show that the VR Cocha format allows to use rotations in a hierarchical structure.

Take care: although this object seems quite simple, it is made with thousands of sides and vertices, and may be too complex if you have few RAM in your computer. It was produced in Basic with a fractal logic and little random corrections so that it would not be too regular. You'll notice that the proportion between two generations is the classical "golden proportion": (1+sqr(5))/2.

Liliana Collazos is a Bolivian architect and a friend of mine. For about four months, I worked with her to represent in virtual reality the project she was creating. An enormous amount of details was changed or added every week, and it would have been absolutely impossible to manage all that without the use of programming techniques.

While visiting this scene, don't forget to use the "View" or "Camera" command of your browser.
