Instanced Rendering
∙ I utilized instanced rendering to optimize the performance of scenes with many identical objects, reducing draw calls and memory usage.
∙ I utilized instanced rendering to optimize the performance of scenes with many identical objects, reducing draw calls and memory usage.
∙ This approach is ideal for large-scale environments like crowds or forests, maintaining visual quality

BRDF Concepts
Disney BRDF
It delves deeply into the "Disney Principled BRDF," which propelled the revolution in physically-based rendering, as well as the subsequent "Disney BSDF" proposed in 2015, providing analysis, summary, and refinement.
Disney BSDF
Solid Angle
Microsurface
The original BRDF model could no longer meet the requirements. As a result, Disney improved upon their previous Disney Principled BRDF and developed the Disney BSDF. This new model was officially introduced at SIGGRAPH 2015 through the talk "Extending the Disney BRDF to a BSDF with Integrated Subsurface Scattering."
