ludus::graphics::renderer::EnvironmentDescription¶

Struct

Borrowed linear HDR latitude/longitude image; Initialize copies all pixels. +Y is north, longitude zero is +X, increasing longitude turns toward +Z.

Fields¶

PixelsOrNull¶

const ludus::foundation::math::Vector4* ludus::graphics::renderer::EnvironmentDescription::PixelsOrNull = nullptr

Tightly packed top-left rows, RGB radiance [0,1e12]; alpha is ignored. Initialize requires Width*Height records and a nonnull pointer; it copies them during the call without retaining the caller's storage.
