What problem does it solve?

Screen-space ambient occlusion adds depth cues by shading occluded regions, making 3D scenes look more realistic in SDL3 GPU applications.

Core Features & Use Cases

• Hemisphere-based SSAO with a dedicated kernel and three fullscreen passes (SSAO, blur, composite) to produce a final ambient-occlusion weighted image.
• Requires a depth texture sampler and a view-space normal MRT to compute occlusion, enabling integration with existing deferred or forward rendering pipelines.
• Practical use cases include real-time scenes with complex geometry, where subtle contact shadows and depth perception enhance visual clarity.

Quick Start

Integrate SSAO by enabling depth sampling, adding a view-space normal MRT, and wiring three fullscreen passes (SSAO, blur, composite) using a 64-sample hemisphere kernel.
