[x3d-public] Over next several weeks, I will be ramping up

Thanks for reminding everyone of this important conversion tool, Michalis.
For everyone's convenience, here is your list of formats:

*	Convert everything to X3D
*	https://castle-engine.io/convert.php

*	Convert to X3D from
<https://castle-engine.io/creating_data_model_formats.php> any model format
supported by Castle Game Engine (glTF, X3D, VRML, Wavefront OBJ, STL,
Collada, 3DS, MD3, Spine JSON and others).
*	https://castle-engine.io/creating_data_model_formats.php

Linking to this service is topmost on the X3D-Edit Import menu, screenshot
attached.

*	X3D-Edit > Import X3D Model from File > Castle Game Engine Convert
to X3D

all the best, Don

STL already contains a simple list of triangles. So if by "tesselation" you
mean "ability to produce triangles from more complex shapes", you don't
really need it for STL :)

Note that CGE, view3dscene and https://castle-engine.io/convert.php

really simple and you can likely adjust it for other purposes / libraries /

The Stereo Lithography (STL) export converter from X3D JSON to STL looks
like low hanging fruit. I just need to find some good tesselation code in
ECMAScript. I already have a basic framework. Can anyone recommend A-Frame,
Three.js, Babylon.js, Unity, X3DOM or X_ITE code for doing tesselation, or
is it built into WebGL?  Meanwhile, I will be working on meshes and creating
a project, etc.

work, testing out CTS coping skills (laying on a different side, taking
breaks), computer hygiene, sleeping hygiene etc.

My wife has given me the thumbs up to return to work remotely.

So if there's any X3D tasks, I should be able to pick some of them up, I
will look at the wishlist.

BTW, has anyone attached Gmail to GPT-3?

Everyone have a merry xmas and happy new year.

Thanks!

John
