[−][src]Struct pbrt::core::lightdistrib::PowerLightDistribution
PowerLightDistribution returns a distribution with sampling probability proportional to the total emitted power for each light. (It also ignores the provided point |p|.) This approach works well for scenes where there the most powerful lights are also the most important contributors to lighting in the scene, but doesn't do well if there are many lights and if different lights are relatively important in some areas of the scene and unimportant in others. (This was the default sampling method used for the BDPT integrator and MLT integrator in the printed book, though also without the PowerLightDistribution class.)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?
Create an error for a missing method specialization. Defaults to panicking with type, trait & method names. S is the encoder/decoder state type, T is the type being encoded/decoded, and the arguments are the names of the trait and method that should've been overridden. Read more
