Positional light
« on: June 26, 2012, 02:48:48 PM »
I have seen that Lights are created as directional by default. I could not find in the documentation of the Light class a method to change it from directional to positional.

To change the type of the light (positional or directional), set the w component of Light.setPositionOrDirection properly ie 0 or 1. You can play with the model viewer with the various parameters of a Light.

For more informations, you can give a look the Light javadoc or better how the fixed pipeline lights works in opengl.
