Load a PBR Model
# Itroduction
This example demonstrates loading glTF model with PBR materials. PBR materials are usually used with image based lighting. ClayGL provide method app.createAmbientCubemapLight
to load a HDR texture, do prefiltering, and the create an AmbientCubeMap
with the prefilerted cubemap for specular lighting. In addition, it will also create an AmbientSH
for diffuse lighting using technique called spherical harmonics
See Basic Theory of Physically Based Rendering to know more about PBR.
