Pretty cool, it seems to use the DOM directly instead of a <canvas> element, amazing it can perform as well as it does with constant css and element manipulation (notoriously slow)

I like that there's collision detection too!

Element manipulation is normally slow because of layout computations, but explicit transforms remove the element from the layout flow (it doesn't affect nor get affected by the sizing and content of other elements), cutting nearly all of that cost. Also, in most browsers explicit transforms get computed on the GPU.

So for this type of case there isn't nearly as much going on between the DOM and the raw graphics code as you might think

I can’t do anything on mobile. Using safari on iOS.

It uses wasd to move, if that helps.

Worked fine in Firefox Mobile on my BlackBerry Key2. That surprised me!

very cool.

you should write a quake clone like this

Nice vaporwave aesthetic in there. Add a fountain with some particles!

Yes, and don't forget a rotating plane with an image on it, preferably showing off high-tech processing such as alpha-blending and soft specularity. It will look like the future, but from the past.

Great ideas, will see what I can do when I get back from work :)

Fun fact, Three.js (the go-to high-level 3D library for JavaScript) actually has a CSS3DRenderer you can slot in for any arbitrary Three.js project: https://threejs.org/examples/#css3d_molecules

Not for any arbitrary Three.js project. the css3drenderer is severely limited

Very cool although noticing lots of tearing on Chrome w/ an nVidia GPU on Windows 10.

You triggered some strange bug in Firefox. I'm getting many notifications that this site captured mouse pointer long after I've closed it.

So close! Enticing checkerboard pattern and some unshaded wood texturing then a hard crash for Firefox Android 68.5.0. Evokes the early 90s which reminds me that anyone who hasn't seen the "Community" episode with the VR parody must watch it immediately: https://youtu.be/z4FGzE4endQ (this seems to be a super-cut which will annoy the writers, bit still)

Interesting that it crashes, this uses nothing but normal html & css for the actual rendering. I have noticed that on machines with slower graphics hardware, there are a lot of glitches (I think it has to do with low VRAM, but not entirely sure).

Yay, view keeps drifting up & left when mouse is grabbed. Looks like Mozilla can't ever seem to get this ancient bug fixed :(

quite heavy

rhacker• 6 years ago

I'm a bit confused... is this just for the awesome factor that you can do this with CSS?

ath924• 6 years ago

yes
