Parameters of the Map Properties

You must select the map type between Basic map and Spectral map.

Note: For more details about precision, you can view Reading Precision.

From Values list, you must select the map type.

From Unit list, you must select the unit.

Note: For irradiance / illuminance map, you must define the position of the map as well as a second point which indicates the normal. For radiance / luminance map, as in any usual luminance simulation, the main parameters are the view point, the position of the map and its orientation. For radiant intensity / luminous intensity, only the orientation is important.
  • In Position group box, you must type the position values of the map in millimeters.
  • In Axis Theta 0 group box, you must type the axis theta 0 values.
  • In Orientation group box, you must type the psi angle value in degrees.

    Phi angle defines the orientation of the map around its axis.

  • In Point at group box, you must type the point at values in millimeters.
  • In Observer group box, you must type the view point values in millimeters.
  • In Vector Phi 0 group box, you must type the vector phi values.
  • In Size and sampling group box, you must define the size and the sampling of the map.
  • In Wavelength group box, you must define the wavelength sampling.

    Information about each wavelength sample is stored in the map.

  • In Intensity type box, you must select the cartesian intensity map type.

    • X As Meridian, Y As Parallel and X As Parallel, Y As Meridian types are adapted for SAE automotive regulations.

      The following images show differences between these maps.

      The source is a small disk which emits in a cone. Each map shows the projection of the cone on the hemisphere. According to the type of map, you can see some deformation of the projection of the cone on the map.

Note: You can select the Data separated by layer check box.
  • In Filename box, you can define the name and the location for the final XMP map file.
