Creates a new PointShadowMap instance. Initializes the shadow moment framebuffer and creates materials for front and back hemisphere rendering. The framebuffer uses RGBA16F format for storing depth moments and a 32-bit depth buffer.
Generates render passes for creating shadow maps from a point light source. Creates two render passes: one for the front hemisphere and one for the back hemisphere of the paraboloid shadow mapping technique.
Array of scene graph entities to be rendered for shadow map generation
The point light entity that casts shadows
An array containing two render passes: [frontRenderPass, backRenderPass]
Gets the framebuffer used for storing shadow moment data. This framebuffer contains the encoded depth moments for variance shadow mapping.
The shadow moment framebuffer containing RGBA16F texture for depth moments
A helper class for managing point light shadow mapping using paraboloid depth moment encoding. This class handles the creation and management of shadow map framebuffers and materials for omnidirectional shadow mapping from point lights.
