Trait Implementations

impl Light for InfiniteAreaLight
[src]

Returns the radiance arriving at a point at a certain time due to the light, assuming there are no occluding objects between them. Read more

Like directional lights, the total power from the infinite area light is related to the surface area of the scene. Like many other lights the power computed here is approximate.

Like DistanceLights, InfiniteAreaLights also need the scene bounds; here again, the preprocess() method finds the scene bounds after all of the scene geometry has been created.

Because infinte area lights need to be able to contribute radiance to rays that don't hit any geometry in the scene, we'll add a method to the base Light class that returns emitted radiance due to that light along a ray that escapes the scene bounds. It's the responsibility of the integrators to call this method for these rays.
