Fourteen, indirect diffuse reflection is used in the sphere
Indirect lighting is divided into indirect diffuse reflection and indirect specular reflection. The irradiance map is used to apply indirect diffuse reflection. Direct light also has diffuse reflection. Compare the two. Direct light kD * albedo / PI * radiance * NdotL; where radiance * NdotL is the illumination, Indirect light: kD * texture(irradianceMap, N).rgb* […]

Solve the throughput problem and refuse to be hesitant! Theoretical support, all in one go!
Introduction This article introduces that when we encountered the problem of twice the write throughput in the master-slave mode of Haidongqing, we tried some processing methods but to no avail. After clarifying the relationship between concurrency, QPS, and response time, we derived an empirical theory. Only then can we help us find the cause of […]
