lightangle - Create or position light object in spherical coordinates
Syntax
lightangle(az,el)
light_handle = lightangle(az,el)
lightangle(light_handle,az,el)
[az,el] = lightangle(light_handle)
Description
lightangle(az,el) creates a light
at the position specified by azimuth and elevation. az is
the azimuthal (horizontal) rotation and el is the vertical
elevation (both in degrees). The interpretation of azimuth and elevation is
the same as that of the view command.
light_handle = lightangle(az,el) creates
a light and returns the handle of the light in light_handle.
lightangle(light_handle,az,el) sets
the position of the light specified by light_handle.
[az,el] = lightangle(light_handle) returns
the azimuth and elevation of the light specified by light_handle.
Remarks
By default, when a light is created, its style is infinite.
If the light handle passed in to lightangle refers to
a local light, the distance between the light and the camera target is preserved
as the position is changed.
Examples
