Today, I focused on implementing various aspects of the volumetric rendering subsystem. This work is critical for enhancing the visual fidelity of the water rendering and introducing new volumetric effects, which are essential for achieving realistic environmental interactions in the engine.

water_reflect: Implemented reflective properties for water surfaces, enhancing the realism of water rendering by calculating reflection vectors based on the viewer’s position and the surface normals.volumetric_programs_use_march: Wired up the volumetric rendering programs to utilize a raymarching approach for rendering volumetric effects, allowing for more complex light interactions within volumes.vol_raymarch: Began development of the raymarching algorithm for volumetric rendering, laying the groundwork for subsequent implementations of effects such as fog and smoke.volumetric_pass_run: Implemented the core function to execute volumetric passes, establishing a pipeline for rendering volumetric effects sequentially within the main render loop.vol_caustics: Initiated the caustics rendering system, which will simulate light patterns created by surface reflections on the volumetric medium, enhancing the visual complexity of water interactions.vol_pass: Scaffolded the volumetric pass structure, defining how different volumetric effects will be processed in the render pipeline.vol_medium: Created an initial implementation of volumetric mediums, allowing the engine to define properties such as density and scattering for various materials.
The volumetric rendering subsystem is now more robust and modular, with foundational components in place. The next step is to continue refining the raymarching implementation and integrate the caustics calculations within the rendering pipeline.
