[vtkusers] Camera - Light - vtkinteractor

[Farshid Dehmeshki]

	Hi all;
	happy new year!

	I have two questions if anyone could help me,

	1. I want to move camera on the special path. so I change camera position and focal point from one point to another but after this setting I have to do rendering again and for big objects it take a long time and causes flickering. if some how I could use this fly-through, without rendering it will be great. It will be much appropriated if some codes are included.

	2. does anybody knows how can I put spot light in the same position as camera in vtkinteracor.
	each time I can get camera position(or camera focal point) and set light to this point but not with intarcter! so I have to render the object again and that is very slow.

	many thanks in advance
	regards farshid
