This allows different levels of * blur to be quickly accessed based on material roughness. It is packed into a * special CubeUV format that allows us to perform custom interpolation so that * we can support nonlinear formats such as RGBE. Unlike a traditional mipmap * chain, it only goes down to the LOD_MIN level (above), and then creates extra * even more filtered "mips" at the same LOD_MIN resolution, associated with * higher roughness levels. In this way we maintain resolution to smoothly * interpolate diffuse lighting while limiting sampling computation. * * Paper: Fast, Accurate Image-Based Lighting * https://drive.google.com/file/d/15y8r_UpKlU9SvV4ILb0C3qCPecS8pvLz/view */ class PMREMGenerator { constructor(renderer) { this._renderer = renderer; this._pingPongRenderTarget = null; this._blurMaterial = _getBlurShader(MAX_SAMPLES); this._equirectShader = null; this._cubemapShader = null; this._compileMaterial(this._blurMaterial); } /** * Generates a PMREM from a supplied Scene, which can be faster than using an * image if networking bandwidth is low.
