complex container¶
-
class complex_container_t : public wt::texture::complex_t
Complex-valued texture. Uses a pair of (real-valued) textures: one for the real part and one for the imaginary part.
Public Functions
-
complex_container_t(complex_container_t&&) = default
-
virtual ~complex_container_t() noexcept = default
-
inline virtual bool needs_interaction_footprint() const noexcept override
Returns TRUE for textures that make use of the surface interaction footprint data.
-
inline virtual vec2_t resolution() const noexcept override
Returns texture resolution represented via \( \frac{\text{texels}}{\vec{uv}} \). May return an approximation. Can be infinite, e.g., for analytic textures. Can be 1, for constant textures.
-
inline virtual std::shared_ptr<spectrum::spectrum_t> mean_spectrum() const noexcept override
Average spectrum of the texture. Returns
nullptrwhen an average spectrum cannot be computed.
-
inline virtual std::optional<c_t> mean_value(wavenumber_t k) const noexcept override
Average value of the texture. Returns std::nullopt when an average value cannot be computed.
-
inline virtual c_t f(const texture_query_t &query) const noexcept override
Samples the texture.
-
virtual scene::element::info_t description() const override
