This Skill enhances the visual fidelity of 3D applications by adding realistic contact shadows in crevices and corners, making scenes appear more grounded and detailed.
Integrate SSAO into your SDL3 GPU application by adding view-normal output to your geometry pass and setting up three additional fullscreen-quad pipelines for SSAO, blur, and composite passes.

To add screen-space ambient occlusion (SSAO) to an SDL3 GPU application, you must output view-space normals and a depth buffer from your geometry pass, then implement separate fullscreen-quad pipelines for SSAO calculation, blur, and composite passes.
Hemisphere-kernel sampling for SSAO is a technique used to calculate contact shadows by sampling view-space normals and depth buffers, generating ambient occlusion factors that add realistic shadows to crevices and corners in 3D scenes.
Yes, implementing SSAO in SDL3 requires view-space normals and a depth buffer generated from your geometry pass. These are essential inputs for the hemisphere-kernel sampling used to calculate accurate ambient occlusion factors.
SSAO compositing requires three specific rendering passes: a calculation pass for the ambient occlusion factor, a blur pass to smooth the results, and a composite pass to blend the occlusion with your scene color.
Yes, this SSAO implementation uses multiple render targets to simultaneously output scene color, view-space normals, and ambient occlusion factors during the geometry pass to efficiently support the multi-pass rendering pipeline.
Your 3D scene lacks contact shadows because it is missing screen-space ambient occlusion (SSAO). Adding SSAO calculates how exposed each point is to ambient lighting, grounding objects and adding realistic depth to intricate geometric details.
