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

201909 - a look into threejs raycaster

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

Some Blender 2.80+ scripting notes

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)

Code refactor, thoughts

Some thoughts about code structure, as I read code, and find some things some hard to follow than others.

Notes about my usage of GIT

My GIT habits :

  • On Windows, through GIT bash

  • No UI, except occasional gitk --all& to visually check branches and commits

  • Use git fetch then git merge --ff-only origin/master

    • I don't like git pull auto-merging feature that messes up the history

  • Use git add -p to :

  • make a quick review of changes before commit
