NES emulation in #VR!
Works on desktop and on Quest (uses controllers for input).
Built using JSNES by @bfirsh, #threejs, and #AFrame @aframevr.

@AdamClarey @bfirsh @aframevr I lend my support for these open source and community driven projects by making and sharing lots of examples to show what is possible with the technology. Consider this "NES emulation in VR" example a proof-of-concept, which I hope others will improve upon. (3/3)

@AdamClarey @bfirsh @aframevr I also love the convenience and simplicity of sharing a VR experience by visiting a website - no downloads or installation necessary.

Thanks to #threejs and #AFrame, creating these experiences is very accessible... (2/3)

[Lee Stemkoski @ProfStemkoski]

@_limbofeather @bfirsh @aframevr Yes, there is a live playable game included; see https://t.co/mgLB5yvEUx, but first read https://t.co/LYeKpwM6DU to learn the controls.
Some people program NES ROM files and make them freely and legally available, like the sample game included above - thanks @PinoBatch!

Special thanks to @MaximeEuziere and the JSNES-lite project (https://t.co/4q4gOepjBy), who is working hard to make NES emulators easier to understand (https://t.co/tDDxmdDy8Y) and easier to use for everyone!

@thraxalicious Your dice simulation is beautiful! 🎲😄
I'm using PhysX, building on the work of @zach_geek, see also https://t.co/ZPgKy2QhHT for another physics demo.

Interactive physics in an #AFrame #VR world. Built using the PhysX component, part of the #VARTISTE project by @zach_geek.

Polyhedral dice are cool.
#AFrame and #threejs are cool.
Time to bring them together!

New demos: physics-based infinite dice tower, and a ball of 1,000 rotating dice (uses an instanced mesh).
Examples live at https://t.co/X890LiaOrQ, free dice models at https://t.co/GDHgNFl4az

[Lee Stemkoski @ProfStemkoski]

Updates on #VR #GameDev with #AFrame and #threejs: added dynamic lighting, ambient occlusion, animated shader effects, and ambient sounds.
After collecting the colorful orbs, vanquish the dark orbs!
(Still work in progress, but code available on GitHub.)

Did you ever point a video camera at a screen that displays what the video camera sees?

Just for fun, created this with #AFrame and #threejs, works on desktop and is extra fun in #VR!

Working on some #VR #GameDev with #AFrame and #threejs. Features randomly generated dungeons, a GPS-style minimap, and collectable objects with particle effects. Still very much a work in progress, but enough to share a video of how it looks so far: https://t.co/39DuAP9eMQ

@AdaRoseCannon I've been focusing on controller based interaction, so I'm not aware of hand tracking issues, but I aspire to create those types of experiences soon!

I'm currently thinking about how to remap controls when an object is held, to manipulate objects more easily. Lots to explore!

[Lee Stemkoski @ProfStemkoski]

Working on new #VR projects with #threejs and #AFrame: new components for movement, selection, and holding objects. Also: components for interactive music players, books, and video games!

@ronchoqa We are all very fortunate, thanks to the developers of #AFrame / @aframevr, for working on the library which makes #VR and #AR development accessible to so many people! 😄

[Lee Stemkoski @ProfStemkoski]

Created some animated shaders in #VR with #threejs and #AFrame: a dissolve effect using Perlin noise, a Mandlebrot fractal with Julia sets, Conway's Game of Life (processing done in fragment shader), and a raymarching demo.

All examples live on GitHub: https://t.co/X890LiaOrQ

Going for a walk in my #AFrame #VR world! Model made with #VRoid, amazing and easy-to-use software. Excellent A-Frame #VRM plugin by https://t.co/pN2wILTqvw, integrates with VMD/BVH motion files. Live example at https://t.co/IHGO1qAu5C.

@giodegas Do you mean some type of AR experience using pass-through mode on Quest, using A-Frame? I'm not sure if pass-through mode is accessible while using a web browser, but even if it was, I don't think the cameras capture images appropriate for the kind of image processing needed...?

[Lee Stemkoski @ProfStemkoski]

@exception_at_0x It's great to hear that everything is going well. Happy coding!
