Stochastic Screen-Space Reflections Implementation
This pull request implements Stochastic Screen-Space Reflections (SSSR) in the Armory3D engine, providing a high-quality visual effect with an optional setting in the SSR section.
Changes
stochasticSSRtossr.glslthat implements the SSSR effect using a stochastic sampling approach.postprocess.glslshader to use the newstochasticSSRfunction when theu_UseStochasticSSRuniform is enabled.u_SSRQualityto control the quality of the SSSR effect.postprocess.hxandpostprocess.hxmlfiles to include a new checkbox and slider to control the SSSR effect.Inspiration
The implementation is inspired by the Blender Eevee SSR and the FidelityFX SSSR, with a focus on visual quality rather than performance.
Example Use Case
To use the SSSR effect, simply enable the "Use Stochastic SSR" checkbox in the post-process settings and adjust the "SSR Quality" slider to control the quality of the effect.
Note: This implementation is not optimized for performance and may have a significant impact on frame rate. Further optimization and refinement may be necessary for production use.
