integrators¶

class integrator_t : public wt::scene::scene_element_t

Generic interface for light transport integrators.

Subclassed by wt::integrator::plt_bdpt_t, wt::integrator::plt_path_t

Public Functions

inline integrator_t(std::string id)

integrator_t(integrator_t&&) = default

virtual ~integrator_t() noexcept = default

virtual sensor::sensor_write_flags_e sensor_write_flags() const noexcept = 0: Indicates how the integrator writes to the sensor, and which capabilities are expected from the sensor (or its underlying film).

virtual void integrate(const integrator_context_t &ctx, const sensor::block_handle_t &block, const vec3u32_t &sensor_element, std::uint32_t samples_per_element) const noexcept = 0

Integrates light transport in the scene, given a sensor element and samples count. The arguments block and sensor_element are only used when sensor_write_flags() sets wt::sensor::sensor_write_flags_e::writes_block_splats, otherwise are ignored.

Parameters:

block – block to write samples to
sensor_element – sensor element that block belongs to
samples_per_element – sample count to use for this element

Public Static Functions
