calculate an accurate intensity for you based on the sun's position.
3. A Goniometric light is one which can emit widely varying amounts of light energy in different
directions. One goniometric source could behave exactly like a point light, another could behave
exactly like a spot light, and a third could look nothing like either of those. A goniometric light gets its
intensity distribution function (how much light goes in any one direction) from an industry-standard
file. Presenter supports CIE (*.cie), IESNA (*.ies), CIBSE (*.cib) and ILUMDAT (*.ldt) files.
Note:
A complete reference manual for all light types is included with the NavisWorks API (see
\API\COM\documentation\shaders.chm). The NavisWorks API is included with NavisWorks and
can accessed via the NavisWorks installer menu.
Each light type has its own parameters, and the editor for a Point Light is shown here:
