Today I worked on the implementation of screen space reflections (SSR) and screen space ambient occlusion (SSAO) within the rendering subsystem. These features are vital for enhancing visual fidelity and realism in lighting interactions within the voxel environment.

SSR Module: Introduced the ssr_fsquad, which sets up a full-screen quad for executing the SSR shader pass. This establishes a foundation for reflection calculations.SSR Configuration: Created ssr_config scaffolding to manage SSR parameters, allowing for adjustable settings such as reflection intensity and roughness.SSR Depth Setup: Implemented the ssr_depth, which captures depth information necessary for accurate reflection rendering. This enables proper occlusion of reflections based on scene depth.SSR Debugging: Set up ssr_debug to visualize reflection calculations during development, aiding in the identification of rendering artifacts or inaccuracies.SSAO Configuration: Initialized ssao_settings to provide user-adjustable controls over ambient occlusion effects, including radius and intensity.SSAO Pass Setup: Established the ssao_pass, which integrates the SSAO calculations into the render pipeline, ensuring it runs alongside other post-processing effects.SSAO Sampling: Started working on ssao_sample, which defines the sampling strategy for ambient occlusion, leveraging a kernel to calculate occlusion values based on neighboring pixels.Kernel Statistics: Set up ssao_kernel_stats to track and debug the parameters of the SSAO kernel, which will assist in optimizing performance and quality.
The rendering subsystem now has a foundational implementation for both SSR and SSAO, with key components in place. The next steps will involve refining the sampling methods for SSAO and integrating the blurring effect for the final output to enhance visual quality.
