Hi Micha- I had similar frustration with rectangular lights. You can
try this script I bludgeoned together and see if it makes life a little
easier (V4 only I'm afraid). The rather severe limitations are:
-that in order for any of the manipulation commands to work, you must
use then on lights made with PlaceAreaLight
-that the lights have permanent point objects attached to them- there is
currently not enuough info in an area light to be able to turn these on
as needed.
-These points are somewhat fragile in their connection to the light-
that is, you can do selPt and move them without moving the light and
they will no longer behave correctly- they are only grouped with the light.
Drag and drop the rvb over a Rhino 4 window and it will register some
new aliases:
1.PlaceAreaLight - asks for a size, a target point and a light center
point and places a square rectangular light oriented to shine from the
center point to the target point. The light has 4 points attached to it
that act as handles for the following 'commands':
2. OrientAreaLight - lets you grab one of the points on the custom
rectangular light and move it around so that it stays pointing at its
target- on a sphere essentially. If you pick any of the points on the
light the sphere is centered on the target point; if you picj the target
point then the sphere is centered on the middle of th light plane and
the target wobbles.
3. SlideAreaLight - pick edge points to slide sideways in the plane of
the light, or pick the center point to slide in and out on the target,
normal to the plane.
4. ResizeAreaLight - pick either of the edge points to resize the rectangle.
5. RotateAreaLight - Pick either edge point and pivot on a axis between
the center point and the other edge point.
