Public Member Functions

 ILight (bool cast_shadows=true)
 m is the object space to world space transformation matrix.

virtual ~ILight ()
bool CastShadows () const
 This method returns true if the light casts shadows, false otherwise.

virtual const Color3 & GetPower () const=0
 Returns the emission power of this object, expressed in W.

virtual Ray GeneratePhotonRay (const Context &context) const=0
virtual void ComputeIrradiance (const Context &context, const Scene *scene, const sheep::Point3 &point, const sheep::Vector3 &geometric_normal, const sheep::Vector3 &shading_normal, const ISurfaceSampler::SampleVector &input, IrradianceSampleVector *output) const=0

Protected Attributes

virtual void toxic::ILight::ComputeIrradiance (  const Context &  context,
const Scene *  scene,
const sheep::Point3 &  point,
const sheep::Vector3 &  geometric_normal,
const sheep::Vector3 &  shading_normal,
const ISurfaceSampler::SampleVector &  input,
IrradianceSampleVector *  output
)  const [pure virtual]
 

Computes irradiance due to this light source. The point and the surface normal are both expressed in world space.

Implemented in toxic::IAreaLight, toxic::PointLight, and toxic::Sphere.
