The matrix used to transform the world coordinates into the light's viewing coordinates is the same as the one used to render the shadow map in the first step ( under OpenGL this is the product of the modelview and projection matrices ).

Thanks for the input, I'd like to move further discussion to Wikipedia : WikiProject Geographical coordinates Also see my page for my idea of how world coordinates should look .-- Plowboylifestyle 02 : 10, 4 Mar 2005 ( UTC)

To determine the position of the Sun and planets, an astronomical ephemeris ( a table of values that gives the positions of astronomical objects in the sky at a given time ) is used, which can then be converted into suitable real-world coordinates.

Concerning exterior orientations, these six parameters ( x, y, z real world coordinates of the camera projection center and the roll, pitch and yaw angles of the camera ) can be assigned to each image by the user at this very point of the workflow.

The metadata include information about the creator of the image, the content ( including description and subject category ), the method of observation ( including facility, instrument and spectral information ), the World Coordinate System ( WCS ) position in the sky, and the publisher of the image.

After the War, the International Jewish Labor Bund, more properly the World Coordinating Council of the Jewish Labor Bund, was founded, based in New York, with affiliated groups in Argentina, Australia, Canada, France, Israel, Mexico, the United Kingdom, the United States and other countries.

As FITS has been generalized from its original form, the world coordinate system ( WCS ) specifications have become more and more sophisticated : early FITS images allowed a simple scaling factor to represent the size of the pixels; but recent versions of the standard permit multiple nonlinear coordinate systems, representing arbitrary distortions of the image.

The list also includes the Polish-based " Education for Democracy " foundation and the " East European Democratic Centre " as well as three Ukrainian organizations : The Ukrainian World Congress, the " Ukrainian World Coordinating Council " and the " Crimean Field Mission on Human Rights ".

Once an observational platform's local " X-Y-Z " axes are expressed numerically as three direction vectors in world coordinates, they together comprise the columns of the rotation matrix ( world ?! platform ) that transforms directions ( expressed in world coordinates ) into equivalent directions expressed in platform-local coordinates.
