Implementation of Percentage Closer Filtering (PCF) and Percentage-Closer Soft Shadows (PCSS) in OpenGL. Features a small ImGui configuration panel for adjusting various parameters at runtime. The first prototype was written as part of a school project, but has since been heavily modified and refactored.
These explanations and code snippets were particularly useful to me when first learning about soft shadow rendering. You may find them helpful as well.
