CONST_D3DLIGHTTYPE

Defines the light type.

Enum CONST_D3DLIGHTTYPE
    D3DLIGHT_POINT       = 1
    D3DLIGHT_SPOT        = 2
    D3DLIGHT_DIRECTIONAL = 3
End Enum

Constants

D3DLIGHT_POINT
Light is a point source. The light has a position in space and radiates light in all directions.
D3DLIGHT_SPOT
Light is a spotlight source. This light is similar a point light, except that the illumination is limited to a cone. This light type has a direction and several other parameters that determine the shape of the cone it produces. For information about these parameters, see the D3DLIGHT8 type.
D3DLIGHT_DIRECTIONAL
Light is a directional source. This is equivalent to using a point light source at an infinite distance.

Remarks

Directional lights are slightly faster than point light sources, but point lights look a little better. Spotlights offer interesting visual effects but are computationally expensive.
