Locks the sun to a certain vector. This effectively mimics the IGDS/MicroStation default sunlight.
X
Defines the X coordinate of the solar lighting directional vector.
Y
Defines the Y coordinate of the solar lighting directional vector.
Z
Defines the Z coordinate of the solar lighting directional vector.
Azimuth from 0 to 360
Controls the bearing of the solar light in degrees ranging from 0 to 360, 0 degrees being North. Clicking OK sets the sun to the specified vector but does not populate the Latitude, Longitude, and GMT offset fields on the Solar tab with the values for the selected vector and angle.
Altitude from -90 to 90
Controls the angle of the sun above (positive values) and below (negative values) the horizon in degrees ranging from -90 to 90. Clicking OK sets the sun to the specified vector but does not populate the Latitude, Longitude, and GMT offset fields on the Solar tab with the values for the selected vector and angle.
-
The solar directional vector defines the exact direction of the solar lighting.
-
When the X, Y, Z coordinates are adjusted, the Azimuth and Altitude angles are updated to reflect the current values.
-
When the Azimuth and Altitude angles are adjusted, the X, Y, and Z coordinates are updated to reflect the current values.
-
When the Use Vector option is not selected, the values in the longitude and latitude boxes feed the X, Y, and Z coordinates and angles on the Solar Vector dialog box. However, changes made to these coordinates on the Solar Vector dialog box are not reflected in updates to the Latitude and Longitude fields.
