Class Documentation¶
-
class fsd_sampler_t : public wt::scene::scene_element_t¶
FSD sampler. The internals work in wavelength-agnostic canonical space (scaled by wavenumber k).
Public Functions
-
fsd_sampler_t(std::string id, const wt::wt_context_t &context) noexcept¶
-
fsd_sampler_t(fsd_sampler_t&&) noexcept¶
-
~fsd_sampler_t() noexcept¶
-
sample_ret_t sample(sampler::sampler_t &sampler, const fsd::fsd_aperture_t &aperture) const noexcept¶
Samples the free-space diffraction ASF, given an aperture. The returned weight is asf/pdf (i.e., cosine foreshortening is NOT accounted for).
-
inline f_t pdf(const fsd::fsd_aperture_t &aperture, const vec2_t xi) const noexcept¶
Queries the sampling density of the free-space diffraction ASF, given an aperture. (approximation)

fsd_sampler_t(std::string id, const wt::wt_context_t &context) noexcept¶
