coderofsalvation / load_remote_GLTF_extras_metadata.gd
Last active May 8, 2024 10:15
programmatically read extras / custom properties from remote GLTF in Godot 4 gdscript
# For more sophisticated use of loading remote GLTF (with extras) use the xrfragment.org spec & xrfragment.gd script
# XRFRAGMENT.ORG is a mini-spec which standardizes 3D metadata without fileformat or platform lock-in
#
# Usage:
#
# load("https://xrfragment.org/index.glb")
# var doc = GLTFDocument.new()
# var state = GLTFState.new()
# #state.set_handle_binary_image(GLTFState.HANDLE_BINARY_EMBED_AS_BASISU) # Fixed in new Godot version (4.3 as I see) https://github.com/godotengine/godot/blob/17e7f85c06366b427e5068c5b3e2940e27ff5f1d/scene/resources/portable_compressed_texture.cpp#L116
# var error = doc.append_from_buffer(body, "", state)

My favorite Javascript patterns

Useful JS Patterns/Functions

NOTE: for 3D JS patterns see my 3D patterns-page

Besides all the classical designpatterns in js, decorating lodash with new mixins, or a simple underscore object can also be useful.

vanilla DOM components reactified using Proxies, see codepen here

Open Cubic Player Nix-file attempt (newbie needs help, this nix-file is stuck on libancient)

Due to lack of nix-skills I gave up on compiling it via nix (and ideally submitting it upstream). For now, I'm just using the AWESOME ocp player via this ~/bin/ocp shellscript:

#!/bin/bash
nix_windows(){
  test -d ~/apps/ocp || {
    mkdir ~/apps/ocp
 cd ~/apps/ocp

installing ALPINE LINUX on any (old) android device using ssh-droid

installing ALPINE LINUX on any (old) android device using ssh-droid (tested: NEO G4 MINIX)

note: bit of unix-skills (vi e.g.) is needed (a very good investment for your future)

  1. install ssh-droid thru playstore, or download/open its .apk file after googling
  2. open ssh-droid
  3. on another laptop/computer ssh into your android device
  4. type mkdir alpine in your homefolder
  5. download the following shellscript below by typing:

modified version of snippy which features easier installation, follows symlinks, bashdown templates and automatic detection of cli vs window

NixOS Lenovo ideapad s540 nvidia GTX1650 powersave

Welcome ideapad s540 GTX1650 Nix-friends (good news ahead)

I've spend way too long to get the NVIDIA-driver to work, as well as taming the overheating problem which has haunted my ideapad forever. I hope this config can save somebody else lots of time (please comment!), as I experienced weird catch22 scenarios because of the dual-video driver.

note: if you laptop still overheats, lower the CPU_SCALING_MAX_FREQ variables.

You can now run apps on the NVIDIA GPU by creating this nvidia-run shellscript-wrapper:
