Percentage Closer Soft Shadows is a popular technique to generate contact hardening soft shadows with shadow mapping. Recent research in shadow generation for translucent objects makes it possible to realize shadows for translucent objects in real-time environments. However, for multiple translucent blockers it is unclear how an appropriate blocker depth can be calculated. In this paper, we propose a method to calculate a blocker depth for multiple translucent blockers and therefore, enabling physically plausible soft shadows for opaque and translucent objects in a single approach.
