This is an unscripted exploration of setting up a 3D project using the micro WebGL2 framework named "W". I run into various issues, work to solve them in the video, and eventually get a very simple 3D scene rendered in the browser.
The corresponding FOSS code is on GitHub: https://github.com/morph-games/w-dungeon -- Look for the tag "video-0" to see the state of the code as it was in this video.
