The light type property defines which type of light source you're using. The light type is set by using a value from the D3DLIGHTTYPE C++ enumeration in the dltType member of the light's D3DLIGHT7 structure. There are three types of lights in Direct3D Immediate Mode—point lights, spotlights, and directional lights. Each type illuminates objects in a scene differently, with varying levels of computational overhead. For general information about how each type of light works, see Introduction to Light Objects.
