详细描述

EnvironmentLight uses cubemaps to implement image-based lighting (IBL), a technique often used in conjunction with physically-based rendering (PBR). The cubemaps are typically expected be based on high dynamic range (HDR) images, with a suitable OpenGL format (such as RGBA16F) that can handle the increased range of values.

There are a variety of tools that can be used to produce the cubemaps needed by EnvironmentLight. Some examples include

• cmftStudio
• IBLBaker
• Lys

HDRI Haven provides many CC0-licensed HDR images that can be used as source material for the above tools.
