yes here it works in HUD but not when walking

you can change Mercator 'globe inventor' his t-shirt'
yesterday the new museum in Belgium is opened with metaHuman

this metahuman can talk and answer about the globe

how cool with microsoft copilot you can now make 3D objects from a picture for free

how cool I made a remake of snow Chaoa to 'make your own wooden structure'

and with 2 levels as ZAPP

and with extra balls and 4 levels

chedk the post

happy christmas, with https://readyplayer.me/avatar you can make christmas glass

karelrosseel82 · December 21, 2025, 10:10pm

how cool this ebook https://www.ixperium.nl/wp-content/uploads/2025/12/EDUsummIT-eBook-2025.pdf
via

new digital technology that I believe in is Learn Apps - mobile and e-learning apps with ZIM JavaScript Canvas Framework components - zimjs.com - ZIMjs learning apps, are becoming more important than ever to be able to create free learning apps by and for students in all languages of the world it is used, and it supports not only normal alphabeth, also Japanese writing system, Chinese characters, RTL (right-to-left) script, Turkish characters, TTS (text-to-speech), voice recognition, 3D+VR, ml5js (machine learning) and so much more!

cool from 2020

drawing app with colors and size possible to change

happy christmasTime a little present idea https://zimjs.com/certificates

happy christmas = Fijne Kerst in Ductch!

from original Dan Zen
2026 will become minecraft kenney-year

/// found this AR christmastree idea
would be cool if also a christmasTree 3D can be placed into the room with ZIM+AR

𝗪𝗛𝗔𝗧 𝗧𝗛𝗜𝗦 𝗜𝗦
What you are seeing here is exclusive material we created two years ago around Christmas. It shows our XR Stager Spatial Computing platform in action, using seasonal 3D assets to explore how digital content moves seamlessly from screen based interaction into spatial experiences.

𝗛𝗢𝗪 𝗜𝗧 𝗦𝗧𝗔𝗥𝗧𝗦
Christmas themed 3D assets were selected and controlled directly on an iPad, turning the tablet into a spatial control surface that allows intuitive interaction. From there, the content was sent live to a Proto Hologram 3D display, demonstrating how touch based input can be translated instantly into spatial output.

𝗪𝗘𝗕 𝗕𝗔𝗦𝗘𝗗 𝗫𝗥 𝗖𝗢𝗡𝗙𝗜𝗚𝗨𝗥𝗔𝗧𝗜𝗢𝗡
At the same time, a Christmas tree with 3D gifts was configured through the XR Stager web platform. Decorations, materials, and structural elements were defined directly in the browser, showing how web based XR enables fast and accessible spatial configuration without requiring dedicated apps or installations.

𝗙𝗥𝗢𝗠 𝗖𝗢𝗡𝗙𝗜𝗚𝗨𝗥𝗔𝗧𝗜𝗢𝗡 𝗧𝗢 𝗠𝗘𝗧𝗔𝗩𝗘𝗥𝗦𝗘
The configured Christmas tree was then placed inside a virtual showroom in the Metaverse, where it became part of a spatial environment rather than a standalone object. This allowed the scene to be explored, presented, and experienced as a coherent digital space.

𝗤𝗥 𝗖𝗢𝗗𝗘 𝗧𝗢 𝗪𝗘𝗕 𝗔𝗥
Each Christmas configuration could be published as a QR code, enabling viewers and visitors to access the same experience on their own devices. By scanning the code, the Christmas tree could be placed virtually at home using WebAR on a smartphone, extending the experience beyond the showroom into personal space.

𝗪𝗛𝗬 𝗧𝗛𝗜𝗦 𝗠𝗔𝗧𝗧𝗘𝗥𝗦
This small Christmas experiment already reflected many principles that define Spatial Computing today, including web first XR workflows, device independent experiences, and continuous pipelines from configuration to hologram to AR. It shows how playful experimentation can evolve into meaningful platform thinking.

Wishing everyone a calm and inspiring Christmas.

so would be nice to have the mincraft kenney in AR, but for the moment only VRbutton is supported into the template https://zimjs.com/015/vr_template.html

found this idea ThreeJS video to track picture of a globe

possible into the future of ZIM maybe?

karelrosseel82 · December 26, 2025, 4:16am

happy with the walking robot minecraft in "ZIMECRAFT"
walk around, turn around, and change the texture

@Abstract can you test it out, (note you can not zoom out very far with maxDistance and not look under the tiles)

Extra firstPerson where you can choose cam from front , back of the person to walk around into the space

here I made the axis visible by the sides of the tiles, and you can walk forward in FirstPerson when clikcing EYES button

Idea to paint onto threejs objects

https://discourse.threejs.org/t/projecting-texture-onto-mesh-and-applying-result-to-mesh-texture-for-mesh-painting/75779/2

how can I do @Abstract
found this example

how cool http://www.cartelle.nl/deathpaint/ if ZIM can do that with own colorPicker

Abstract · December 27, 2025, 2:53am

TextureActive.

karelrosseel82 · December 27, 2025, 2:57am

onto a 3D object possible? can you make example?

Abstract · December 27, 2025, 3:14am

When you make a TextureActive it is a canvas texture on a three.js object. So when we draw with the pen, for example, on a TextureActive, it is drawing on the texture of an object. That object can be a model.

Try it - set the texture of a model to a TextureActive and have the pen draw on the texture. Sort of like https://codepen.io/zimjs/pen/dPogxNB

karelrosseel82 · December 27, 2025, 7:01am

oh it can be a christmasBall
haapy christmas and joyfull 2026

I want to make worlds in 3D for free and found out this is possible with API js at
https://worldgen.github.io/
can you test it can work new WorldGen() with ZIM

# Use our API to generate a 3D scene
worldgen = WorldGen()
worldgen.generate_world("<TEXT PROMPT to describe the scene>")

what a christmaspresent @Abstract if it would work to walk in.. with 2 lines of code..

Abstract · December 27, 2025, 7:45pm

Go ahead - I do not think there is anything we need to do.

karelrosseel82 · December 28, 2025, 6:46am

how cool, I fixed it so in EYES and BACK modus the arrows turn 'in correct cross.index positions' (not when in CAMERA modus)

so when in EYES modus

test it at

newer version mineZIMcraft

https://zimjs.com/zapp:E_UVQRV
with VR button and panel to hide the colors of the borders

I want to make something like this https://www.demaaltafels.be/panda-resort.html

but here her the panda walks towards your finger that pressed the screen, much eadier for children

Abstract · December 28, 2025, 3:18pm

work it out - I guess it does not fit on portrait and that is why you can't see the sides - if that is what your question was.

karelrosseel82 · December 31, 2025, 7:49am

happy I made the ice minecraft slingshot

I learn kids how to correctly place pictures onto the stage with .loc(x,y).place() code
as

tip: you can rebuild it yourself, but it was not easy to place blocks with one mousefingerpoint, so I added some extra code in this newer version

my son is minecraft lover.. but I like to let him play only the ZIM minecraft because he is only 7 years.. and let him build block constructions as this

joyfull 2026!
