class response_t : public wt::scene::scene_element_t¶
Sensor’s response function. This is responsible to transform spectral samples to film pixel data. f() converts spectral samples are converted to power values using the sensor’s sensitivity spectrum for each channel. An optional tonemapping operator, get_tonemap(), transforms the final multichannel data using some mapping, e.g., gamma correction.
Subclassed by wt::sensor::response::RGB_t, wt::sensor::response::XYZ_t, wt::sensor::response::monochromatic_t, wt::sensor::response::multichannel_t
