In lighting, the second point in a two-point placement that determines where the light is cast. For point lights, interest represents the falloff point located on a sphere centered on the light location that is tangent to the interest point. For distance and spot lights, interest represents an idealized point on a line from the light location in the direction that the light is cast. Note that once the light is placed, this point is normalized.
