rotoglup / 202003 - a look into threejs API.md
Last active March 13, 2020 08:16

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...

rotoglup / 202003 - a look into threejs shaders.md
Last active March 13, 2020 08:02

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

A personal list of traps if fell into using threejs

applyMatrix on Geometry does not flip faces when needed

applyMatrix, on Geometry or BufferGeometry, does not flip faces indices when applying a matrix that flips normals (determinant < 0).

see mrdoob/three.js#17361

or

  • Set-NetConnectionProfile -Name "Ethernet" -NetworkCategory Private

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

Code refactor, thoughts

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

Booleans are values

(m_ui.SomeCheckBox->checkState() == Qt::CheckState::Checked) ? true : false

Should probably just be
