Probably not, there is an impressive interactive 3D point cloud rendering, which only shows up after a few seconds. Perhaps you missed that?

How many seconds? I see a discord button, and then some weird blob thing wobbling around. After 30 seconds I got bored of watching it.

In that case you didn't miss anything. Weird wobbling blob thing is the "impressive interactive 3D point cloud".

Oh no, not another "join our discord to use it".

Its a weird choice of UI. Why do companies do this? Is it a development shortcut or something?

> Its a weird choice of UI.

Yeah for sure. I guess one advantage is that since it's already in a chat, people can react and talk about it as it's happening.

Landing page is awesome, wonder how it was created

Thank you! I worked on this

We start with a point cloud generated from the model which has color and normal and render each particle as a little hexagon with metallic and iridescent shading. Each particle is given a position and velocity in a texture. Each frame we do a physics step that writes to these textures with fragment shaders. We sum the forces into the velocity texture:

- mouse interaction force

- flow force from time varying curl noise

- spring force to return to original position

- air resistance

last we do a euler step to update position texture. There’s masses of free parameters to control forces and materials, the animation is created by changing parameters per-particle over time

Tech: three.js, GLSL & TypeScript

You should be able to see the blob form models – perhaps there's some error when it runs on your system. It relies on floating-point textures which aren't supported everywhere

If you view this link https://lumalabs.ai/genie?s=1&d=-4, do you see the models more clearly?

If you _don't_ I'd be curious if any errors are reported in console

Yes with s=1?d=-4 the models are completely clear. I assume the semitransparent glittery look is intentional artistic choice."weird blob" weren't my words but I can imagine how someone could describe it that way considering that half of the time you see the transition animation during which it's much harder to recognize the object.

Both a dev shortcut as well as a stickiness play. Adding a Discord server is like installing a smartphone app.
