What if terraforms had link to MP4 in the metadata?

But would require a render server snapshotting the piece and betray the composition some
We have a gif server for discord that does that btw but decided not to deploy bc we’re not sure best way to do it efficiently, aid anyone here has strong backend design background and knows a cost efficient way to compute and serve 11k 15mb gifs daily, holler
Haven’t gotten around to looking into that yet but maybe someone here knows the best pattern for keeping compute/bandwidth costs way down for something like that

any Terrain mode parcels all technically dynamic
I'd have to do some tests to observe what the threshhold for change is, but bc the whole castle is floating up and down, it samples the noise space at different positions over time
it's very subtle tho and perceiving the change visually is only possible over long time spans
so the sample rate could be low

Perfect loop

ffmpeg -i video/simple.mp4 -filter_complex "[0:v]trim=duration=6,setpts=PTS-STARTPTS,scale=416:600,fade=out:st=5:d=1:alpha=1[fadeout];[0:v]trim=duration=6:start=1,setpts=PTS-STARTPTS[scaled_input];[scaled_input][fadeout]xfade=transition=fade:duration=2:offset=4" output.mp4

nvidia

worth getting hardware accelerated ffmpeg?

https://docs.nvidia.com/video-technologies/video-codec-sdk/12.0/ffmpeg-with-nvidia-gpu/index.html

https://trac.ffmpeg.org/wiki/HWAccelIntro

the real bottleneck is this:

await new Promise((resolve) => setTimeout(resolve, 8000)); // Simulate frame exporting

Canvas as texture?

NFT drop

snapshotting holders

idea:
get info about NFTs held from each holder
generate assets from it?

4.6 AR to host 4 GB of files on arweave

get ascii from terraform, generate particles from it? create atlas + particles or use framework?

petals falling, like a sakurai tree

janusweb /tree/ (rip)

decaying world? shield? room? playcanvas site?
yard-sale/dist/config.json for example
can search and replace? it's only referenced there

just changed a couple places

allocate a number of M3 NFTs into the mix, randomize into the 3D scenes, then airdrop to holders after the reveal

  • boomboxheads
  • chainbreakers
  • M3TV video
  • chuddies
  • retrodoge
  • genesis pass
  • cryptoavatars
  • vipe heros
  • voxel wearables

name idea: Mementos

Fixed camera only, no flying around

launch collection from party dao? so royalties go back to whoever contributed nfts?

Scenes

Castle in the Sky

Internet Archive model

Terraform + particles

threejs / webxr app?

aframe has weird issue, won't play video sometimes

modelviewer + animated texture (video supported)

janusweb + ambient lighting?

airdrop pre-reveal state nfts, then do reveal

NOTE: post processing = no VR/AR support
modelviewer + video + post processing? https://modelviewer.dev/examples/postprocessing/#selective-effects bloom
