Based on my looking at ThreeJS r115dev source code, while trying to figure out how to customize the lighting by writing my own shader.

Materials

ThreeJS has the following Material classes :

• MeshBasicMaterial, not affected by lights
• MeshLambertMaterial: lighting is computed at each vertex, for diffuse lighting, and interpolated in gouraud like fashion

Once more, I'm struggling to wrap my head around the threejs API, here are my notes.

IMPORTANT base on threejs r114 (march 2020)

API topics covered :

• Scene and Object3D, hierarchy, transforms
• Maths, linear algebra
• DirectionalLight, as I'm currently trying to understand how to attach one of them to a Camera...

Scene, view, collections, etc.

Create a new collection

collection = bpy.data.collections.get(collectionName)
if collection is None:
    collection = bpy.data.collections.new(collectionName)
    bpy.context.scene.collection.children.link(collection)

A look into threejs raycaster

I've been looking at the current master source code, not a specific version : github commit b3ce68b4 on sept. 2019.

The source code is located in src/core/Raycaster.js, and the doc is online.

A Raycaster instance is constructed given a ray (origin point + direction vector) and a range on this ray (near, far distances), and offers the following API :

• intersectObject( object, recursive, optionalTarget ) : Array

A look into threejs editor

My notes while reading the source code from threejs Editor app, as I've been curious about :

• the editor architecture
• the undo/redo system
• the camera control behaviour & code
• the object transform gizmos behaviours & code

          and was not of much use anyway

   QUICK NOTES:
      Primarily of interest to game developers and other people who can
