Just messing around with dynamically changing the light color from Grasshopper.

Thanks for sharing thoughts.

Note, this has some implications on the UNDO stack...

This is the actual code...can be used for anything.  I started using it with PointClouds to update them dynamically, but yes, it works with anything. 

Rhino.DocObjects.ObjRef obj = new Rhino.DocObjects.ObjRef(id);
Rhino.DocObjects.LightObject lobj = obj.Object() as Rhino.DocObjects.LightObject;
lobj.LightGeometry.Diffuse = col;
lobj.LightGeometry.Intensity = pow;
lobj.CommitChanges();

And as Dhruv suggests, I would be interested to fold this direct-modification approach into some of the HDT tools. Would you be opposed to my shamelessly copying your brilliant technique?

WHOA! did not know you could use set one guid to get non-GH-Friendly objects. Awesome!!!

Try this code in a VB component:


Dim objref As New docobjects.ObjRef(x)
Dim l As Light = objref.Light
l.Diffuse = y
l.Intensity = z
doc.Lights.Modify(x, l)

 

Connect the ID to the x input, set it as Guid, connect a color to the y input and a slider to the z input (add a third input).

hey

Great idea. . is this a cluster u wrote/made? 

u should definitely bundle it with a plugin or HDT tools 

Cheers

is there any chance to see this as a plugin or component?
