MeshGlintMaterial

Far from production ready - you probably need to fix it before using in a real project

Implementation

This is a very early version and some simplifications were made to implement it. Contributions and comments are welcome, especially when it comes to lighting and blending the effect inside the THREE.MeshPhysicalMaterial.

ParallaxMaterial extends THREE.MeshPhysicalMaterial. This means that it inherits the same constructor, properties, and methods, while also introducing additional features described below. The material can have significant impact on performance, but I’m looking into simplifying the glints and releasing a performance version.

Three.js implementation of Procedural Physically based BRDF for Real-Time Rendering of Glints.

Dictionary

The material is currently provided with 1 base dictionary for glints and can have a significant effect on performance. https://github.com/ASTex-ICube/real_time_glint_dictgenerator

Constructor

Instead of one set of parameters, you provide two - one for THREE.MeshPhysicalMaterial and one for MeshParallaxMaterial

new MeshParallaxMaterial(
  MeshPhysicalMaterialParameters,
  MeshGlintMaterialProps
);
