- Added a new 3D rendering pipeline section in the documentation, detailing initialization, VKBuilder, and asynchronous frame handling. - Updated the Ambient Occlusion module to support depth-based sampling, allowing for improved visual fidelity in 3D scenes. - Introduced new shader functionalities for ambient occlusion and global illumination, enhancing the overall rendering quality. - Updated GBuffer to include hardware depth texture for more accurate depth sampling in 3D rendering. - Enhanced the RenderControl to manage new features for ambient occlusion and global illumination, ensuring they are enabled by default.
