Syntax
camlight('headlight')
camlight('right')
camlight('left')
camlight
camlight(az,el)
camlight(...,'style')
camlight(lgt,...)
camlight(ax,...)
lgt = camlight(...)
Description
camlight('headlight') creates
a light at the camera position.
camlight('right') creates
a light right and up from camera.
camlight('left') creates
a light left and up from camera.
camlight with no arguments
is the same as camlight('right').
camlight(az,el) creates
a light at the specified azimuth (az) and elevation
(el) with respect to the camera position. The camera
target is the center of rotation and az and el are
in degrees.
camlight(...,'style') defines
the style argument using one of two values:
local(default) — The light is a point source that radiates from the location in all directions.infinite— The light shines in parallel rays.
camlight(lgt,...) uses the light specified by
lgt.
camlight(ax,...) uses the axes specified by
ax instead of the current axes.
lgt = camlight(...) returns
the light object.
camlight sets the light object Position and Style properties.
A light created with camlight does not track
the camera. In order for the light to stay in a constant position
relative to the camera, call camlight whenever
you move the camera.
Examples
Move Light Object
Create a light positioned to the left of the camera and then reposition the light each time the camera moves.
surf(peaks) axis vis3d h = camlight('left'); for i = 1:20 camorbit(10,0) camlight(h,'left') pause(.1) end
