ShDiffuseSummary class Lighting and environment
What describeDiffuseSphericalHarmonics measured about a coefficient set.
Constructors
- ShDiffuseSummary({required Vector3 mean, required Vector3 minimum, required Vector3 maximum, required double negativeFraction})
Properties
- constantDeviation → double
-
How far the field strays from constant, as
max(|value - mean|) / max(mean)over every sampled direction and channel. Zero for a perfectly uniform environment.no setter - hashCode → int
-
The hash code for this object.
no setterinherited
- maximum → Vector3
-
Highest per-channel radiance any direction evaluates to.
final
- mean → Vector3
-
Mean reflected radiance over the sphere. For coefficients projected from
an environment this equals the environment's average radiance, so a
constant environment of radiance
Lround-trips tomean == L.final - minimum → Vector3
-
Lowest per-channel radiance any direction evaluates to. Meaningfully
negative values mean ringing (or a bad bake).
final
- negativeFraction → double
-
Fraction of sampled directions where any channel evaluates negative.
final
- runtimeType → Type
-
A representation of the runtime type of the object.

Object other) → bool -
The equality operator.
