SpletThe Percentage-Closer Soft Shadows (PCSS) algorithm computes a variable kernel size based on the distance between the relative position of the receiver point, an approximation of the blocker, and the area light. It produces perceptually plausible soft shadows that … SpletThe PCSS algorithm: By estimating a penumbra width based on light size, average occluder distance and receiver distance (see Eq. 1), the filter kernel size is adapted, generating visually...

SpletThe Percentage-Closer Soft Shadows (PCSS) algorithm computes a variable kernel size based on the distance between the relative position of the receiver point, an approximation of the blocker, and the area light. It produces perceptually plausible soft shadows that harden on contact (see screenshot above).
Splet02. sep. 2024 · It is important to realize that this algorithm has its drawbacks. Look again at figure 6 and the blocker. Now imagine you have not one but two such blockers where one of them (call it b1) is very close to the light source and the second one (call it … SpletThe Percentage-Closer Soft Shadows (PCSS) algorithm computes a variable kernel size based on the distance between the relative position of the receiver point, an approximation of the blocker, and the area light.
