    // Make a granite-like volumetric pattern.

    // Note the keyword "value", followed by two rows of three parameters

    // each. 

    // This is an example of value-gradient. A gradient is a function which 

    // interpolates many values, which may be numbers, colors, or entire

    // patterns and materials.

    // By convention numeric gradients are called value-gradients, color ones

    // are named color-gradients and so on.

    // As a function a gradient associates a value to a real variable.

    // You can imagine it in cartesian coordinates, putting the variable on 

    // the abscissas and the associated value on the ordinates.

    // Here the first expected argument is the abscissa at which the value

    // of the function is specified, then the value follows. The value is

    // specified both at the right and at the left of the abscissa in order

    // to model discontinuities, so it is composed by two numbers.

    // You can specify how many abscissas (and values) you want.

    // This gradient is used to model the output of our fractal pattern,

    // that we will use to describe the spatial density of the cloud.

    // Here the gradient smoothly blends from the value of 1 at the point 0.3, 

    // to the value of 0 at the point 0.5.

    // Normally the output would be a value between 0 and 1, but we

    // make it droppoff rapidly from 1 to 0 to model masses of clouds that

    // are denser at their center and that disappear at their boundaries.

    // It has been specified with a single value of 1 and then with the

    // pattern we modeled before. The value of 1 will be used as a input to 

    // cloudpattern1, which will scale its output by this factor. In

    // this case there will be no scaling, and the output will go from 1 to 

    // 0, as we stated above.

    // The "shadow-caching" and "density-caching" attributes specify the use of 

    // two different caching mechanisms that will be used to speed-up

    // computations. They both require a bounding box where to work, and

    // the density cache also requires the maximum allowed memory

    // occupancy, which is expressed in Kb (here 2048, i.e. 2 Mb).

Python27とcgkit install　（Windows7 32bit）

Python2.7.10をインストールするとpipもインストールされました。とても便利になりました。
pythonのモジュールはwhlが多くなってきました。

>pip install hoge****.whl

のような感じで簡単にインストールできます。

■Python2.7.10をインストールした後、
Windowsの環境変数Pathに以下を追記します。
気をつけて行います。既存のパスの最後に付けます

;C:\Python27;C:\Python27\Scripts

■ここで再起動します。

■次に、以下からダウンロードします。

http://www.lfd.uci.edu/~gohlke/pythonlibs/

Pillow-2.8.2-cp27-none-win32.whl
pygame-1.9.2a0-cp27-none-win32.whl
ode-0.13.1-cp27-none-win32.whl
PyOpenGL-3.1.1a1-cp27-none-win32.whl
cgkit-2.0.0-cp27-none-win32.whl

をダウンロードします。
またVpythonを使いたいならば
VPython-5.74-cp27-none-win32.whl
と
Microsoftから
VCForPython27.msiをダウンロードして
インストールします。

以下は、試したログです。
