Perlin Noise (fBm) を使ったカメラ揺れエフェクト

Perlin Noise (fBm) を使ったカメラ揺れエフェクト

概要

Perlin Noise （fBm 関数）をオブジェクトの動きに取り入れることによって、色々と面白い効果が生み出せます。例えば、これを位置と回転に適用するだけで、カメラの手ブレ風エフェクトなどを作り出せます。

Using Borg and Google Cloud Storage for backing up personal projects

Why do you prefer [Borg] over [git-lfs]/[git-annex]?

  • GitHub LFS has a 2GB limit on file size. This never works with large projects like video productions.
  • git-annex uses symlinks to manage annexed files. This doesn't work well on Windows.

So my conclusion at the moment is that Borg is the best backup software for mid/large-sized personal projects.
