Reality Check

Just for those of you who might be concerned about the Climate Change, here are couple of sobering insights:

• Neil deGrasse Tyson's perspective on climate change: YouTube Video
• My perspective, with statements from two AI entities: Climate Change

Localized and optionally customized three.js

IF, for whatever reason, you might need to locally run the three.js Editor and Examples (Docs) then here is a possible way of doing it with python.

Note: this repository also provides optional customized files which can provide additional functionality currently not available in the Editor. These files should be implemented as either all or none. Also try using only some of these files but don't get surprised if eventually something doesn't work properly.

Maybe consider learning how to modify these files yourself since three.js might implement some features in the future that would not be available in the current optional files or might even break their functionality. This was tested as working with r158 (even r159dev).

Requirements

Required repository - download and extract the zip file from:

• master or dev branch or releases of the three.js, which when unzipped will create the main folder
  • Possible main folder definitions could then be:
    • three.js-master or three.js-dev or three.js-rXXX or some custom name

The simplest requirement and approach for running:

• python3
  • get the Required Repository as stated above and unzip it to create the main folder
  • add to the main folder the index.html file found in the Required folder of this repository
  • use Terminal / Command Prompt, navigate to the main folder and run either of the following commands:
    • python3 -m http.server or python3 -m http.server 8000 --bind 127.0.0.1
  • access the main page in your browser at http://localhost:8000
  • if you decide to use the optional customized files then read below on how to install all of them

As an alternative, either of the following 2 choices below should also work:

• python + Flask and flask_cors packages
• VS Code + python extension (from Microsoft Store) + Flask and flask_cors packages

Packages are normally installed with pip, for example: > pip install Flask or > pip install flask_cors

Flask Folder Structure

• Required files for python / Flask run (add each file to the main folder):

  • app.py
  • __init__.py
  • index.html
  • 404.html

• To run the Flask server:

  • navigate to the main folder in terminal and type python -m app
  • or open the app.py file in VS Code, wait for it to find python interpreters and press F5
  • In the browser go to http://localhost:5000 to see the page

I would recommend using VS Code since it allows to start / stop the server and edit files, all in one app.

Optional Custom Mods (use all or none)

These files / folders should be placed in their corresponding folder and replace any existing files:

file / folder	destination
sw.js (file)	main folder/editor/
Strings.js (file)	main folder/editor/js/
Loader.js (file)	main folder/editor/js/
Editor.js (file)	main folder/editor/js/
Menubar.File.js (file)	main folder/editor/js/
ui.three.js (file)	main folder/editor/js/libs/
3DMLoader.js (file)	main folder/examples/jsm/loaders/
BIMLoader.js (file)	main folder/examples/jsm/loaders/
ColladaLoader.js (file)	main folder/examples/jsm/loaders/
FBXLoader.js (file)	main folder/examples/jsm/loaders/
IFCLoader.js (file)	main folder/examples/jsm/loaders/
IFCLoader.js.map (file)	main folder/examples/jsm/loaders/
ifc (folder)	main folder/examples/jsm/loaders/
MTLLoader.js (file)	main folder/examples/jsm/loaders/
USDZLoader.js (file)	main folder/examples/jsm/loaders/
XYZLoader.js (file)	main folder/examples/jsm/loaders/
LDRAWLoader.js (file)	main folder/examples/jsm/loaders/
ldraw-parts-library-master (folder)	main folder/editor/
PRWMLoader.js (file)	main folder/examples/jsm/loaders/
3DMExporter.js (file)	main folder/examples/jsm/exporters/
OBJExporter.js (file)	main folder/examples/jsm/exporters/
PLYExporter.js (file)	main folder/examples/jsm/exporters/
USDZExporter.js (file)	main folder/examples/jsm/exporters/
ColladaExporter.js (file)	main folder/examples/jsm/exporters/
chevrotain.module.min.js (file)	main folder/examples/jsm/libs/

Optional repository - download and extract the zip file from:

• ldraw-parts-library for local LDRAW support, which when unzipped will create the ldraw-parts-library-master folder mentioned above

Customized features would be mainly Editor related:

• Automatic addition of DirectionalLight to the new scene
• Customized PDB, PRWM, LDRAW and XYZ loaders
• Unofficial BIM loader (dotbim based)
• Customized 3DM loader / exporter:
  • exporter is unofficial and can export textured meshes, points and line segments
  • loader has been modified to support the above mentioned exported 3dm files
• Customized USDZ loader / exporter:
  • can approximate transmission effect
  • USDZ (flipY) as an additional menu export option that can flip exported textures
• Localized IFC loader
• Customized OBJ exporter:
  • it will export MTL file along with the OBJ model / textures
• Customized MTL loader to support the above mentioned exported MTL file
• Customized PLY exporter:
  • converts material color to vertex color if the material has no texture
• Customized DAE (Collada) loader:
  • includes support for THREE.Points
• Customized FBX loader:
  • includes support for THREE.Points
• Added DAE (Collada) exporter, which was officially removed
• Added support for loading USDZ zipped file
• Added support for loading 3DS + textures zipped files
• Added support for loading FBX + textures zipped files
• Added support for loading OBJ + MTL + textures zipped files
• Added support for loading GLTF + BIN + textures zipped files
• Added support for loading DAE (Collada) + textures zipped files
• modified ui.three.js file allows using DDS and KTX2 images as maps
• modified chevrotain.module.min.js fixes the unreachable code warnings

There might be bugs.
