a virtual light for 3D rendering
<p>
<a class="el" href="a00954.html" title="a virtual light for 3D rendering">vtkLight</a> is a virtual light for 3D rendering. It provides methods to locate and point the light, turn it on and off, and set its brightness and color. In addition to the basic infinite distance point light source attributes, you also can specify the light attenuation values and cone angle. These attributes are only used if the light is a positional light. The default is a directional light (e.g. infinite point light source).<p>
Lights have a type that describes how the light should move with respect to the camera. A Headlight is always located at the current camera position and shines on the camera's focal point. A CameraLight also moves with the camera, but may not be coincident to it. CameraLights are defined in a normalized coordinate space where the camera is located at (0, 0, 1), the camera is looking at (0, 0, 0), and up is (0, 1, 0). Finally, a SceneLight is part of the scene itself and does not move with the camera. (Renderers are responsible for moving the light based on its type.)<p>
Lights have a transformation matrix that describes the space in which they are positioned. A light's world space position and focal point are defined by their local position and focal point, transformed by their transformation matrix (if it exists).<p>

A Headlight is always located at the camera and is pointed at the camera's focal point. The renderer is free to modify the position and focal point of the camera at any time. A CameraLight is also attached to the camera, but is not necessarily located at the camera's position. CameraLights are defined in a coordinate space where the camera is located at (0, 0, 1), looking towards (0, 0, 0) at a distance of 1, with up being (0, 1, 0). Note: Use SetLightTypeToSceneLight, rather than SetLightType(3), since the former clears the light's transform matrix.
