We were pretty sure 2018 would be the last time we did this survey. After all, the JavaScript ecosystem can’t very well keep changing again, can it? But what do you know, turns out JavaScript isn’t quite done changing just yet! And so after over 21,717 respondents took this year's survey we had to dig up our components and charts, curse us-from-a-year-ago for writing such crappy code, and get to w
これはThree.js Advent Calendar 2019の14日目の記事です。 3年前に以下の記事を読んでWebGL Inspectorを使い、デバッグ処理でWebGL Inspectorに凄くお世話になりました。 WebGLの開発やデバッグに便利なブラウザ拡張機能をつかってみよう 「Three.jsにBaylon.jsみたいなDebug modeある?」という議論を見つけて気になったので、現状のWebGLデバッグツール状況を調べてみました。 Three.jsフォーラム - Does three.js has some “scene debug mode” or plugin? (like babylon.js DebugLayer) 消失したデバッグツール WebGL Inspector 最終更新日(github):2017/02/22 去年はまだChromeウェブストアにあった
