Incoming radiance
WebJul 25, 2024 · A path tracer, determines this incoming radiance recursively by tracing a ray from \(x\) towards \(\omega_i\) and computing the outgoing radiance at the intersected point for direction \(-\omega_i\). We are more concerned with direct lighting. Thus, we just have to figure out whether the ray intersects the polygonal area light. If so, we ... WebJan 14, 2009 · The Earth’s climate is a solar powered system. Globally, over the course of the year, the Earth system—land surfaces, oceans, and atmosphere—absorbs an average of about 240 watts of solar power per square meter (one watt is one joule of energy every second). The absorbed sunlight drives photosynthesis, fuels evaporation, melts snow and ...

We call the new method radiance caching. The incoming radiance at a point is represented by a vector of coefcients with respect to spherical or hemi-spherical harmonics [9]. Due to the basis orthogonality, the illumination integral evaluation (Eq. 1) reduces to a dot product of the interpolated incoming radiance coef-cients and the BRDF ...
