Today, I focused on implementing the depth of field (DoF) post-processing effect within the rendering pipeline. This is a critical enhancement for visual fidelity, as it allows for more realistic focus transitions in the scene.

Depth of Field (dof_programs): Implemented dof_programs_unload, which properly releases shaders and associated resources when no longer needed, optimizing memory usage.Depth of Field (dof_pass): Began the development of the dof_pass, which will serve as the new rendering stage to handle depth of field computations, ensuring it integrates smoothly with the existing render pipeline.Depth of Field (dof_gather): Completed the dof_gather function, which samples the scene to collect color and depth information needed for the DoF effect, with attention to efficient texture access patterns.Depth of Field (dof_quad): Started implementing the dof_quad, which will represent the screen-space quad used for applying the DoF effect in a fragment shader.Depth of Field (dof_focus): Added functionality for dof_focus, allowing users to set the focal distance dynamically, enhancing control over the DoF effect.Depth of Field (dof_coc): Initiated the dof_coc (circle of confusion) calculations, which are essential for determining which parts of the scene should appear in focus versus out of focus based on their distance from the camera.Code Cleanup: Performed various minor cleanups and formatting changes throughout the modules to improve code readability and maintainability.
The depth of field implementation is progressing well, with foundational components in place. The next step will involve integrating the dof_coc calculations into the rendering pipeline and refining the dof_pass to ensure correct visual output.
