class complex_constant_t : public wt::texture::complex_t

Constant (complex-valued) texture.

Public Functions

inline complex_constant_t(std::string id, std::shared_ptr<spectrum::spectrum_t> &&spectrum)
complex_constant_t(complex_constant_t&&) = default
virtual ~complex_constant_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 nullptr when 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.
