This article originates from a frequently asked question during my interview for a graphics programmer position: What is the Fresnel term in microfacet BRDF, and what does it mean in physics?
Steps to implement a virtual shadow map, presenting an idea to avoid readback operations in virtual shadow map rendering.
Discusses techniques for optimizing Unreal Engine by moving resource initialization tasks from the main render thread to auxiliary threads. Offers solutions to minimize game thread stuttering caused by render resource creation.
Package Android with Unreal without Android Studio! If you don’t want UE to pollute your local Android environment or need to package Android with multiple versions of UE, try this method!
Use perfetto to capture and profile gpu counters on Snapdragon & Mali gpu.
A postmortem of an unsuccessful async-compute experiment on Mali GPUs, and what GPU counters revealed about the real parallelism between the Tiler and Execution Engine.
A Bistro benchmark that ran at 150+ FPS on Adreno 840 dropped to around 40 FPS on MTK9500 / Mali, with nearly 20 ms spent in binning. After several failed geometry-side optimizations, the issue turned out to be the combination of VkCmdDrawIndirect and gl_BaseInstance-based per-draw indexing.
