A lightwarp is a technique of which an object in the geometrical world [[refracts]] light based offon the [[Unit vector|direction]] and [[Intensity (physics)|intensity]] of the light. The light is then [[Wave function|warped]] using an ambient diffuse term with a range of the [[color spectrum]]. The light then may be [[reflectively]] scattered to produce a higher [[depth of field]], and [[refracted]]. The technique is used to produce a [[Style_(visual_arts)#Stylization|unique rendering style]] and can be used limit [[overexposure]] of objects. Games such as [[Team Fortress 2]] use the rendering technique to create a [[cartoon]] [[cel shaded]] stylized look.<ref>{{Cite web|url=https://hal.inria.fr/inria-00449828|title=Radiance Scaling for Versatile Surface Enhancement|first1=Romain|last1=Vergne|first2=Romain|last2=Pacanowski|first3=Pascal|last3=Barla|first4=Xavier|last4=Granier|first5=Christophe|last5=Schlick|date=February 19, 2010|publisher=ACM|via=hal.inria.fr|doi=10.1145/1730804.1730827}}</ref>
