A Light node is placed into the scene graph to illuminate all lit geometry (geometry that has lighting enabled and has vertex normals).
If you want a light, you should create a vtLightSource node and add it to your scene graph. To move or orient the lightsource, make it a child of a vtTransform node. The light will illuminate the entire scene.
| vtLightSource::vtLightSource | ( | int | LightNumber) |
Makes a lightsource, which is placed in the scenegraph in order to position the light.
| LightNumber | Each light should use a different light number which should be one of the valid light numbers for the current OpenGL implementation. Only light numbers up to 7 are guaranteed by default. The convention, higher up in vtlib, is to use light number 0 for the sun. |
