Release of the first dataset for Openvoxels, a DAO whose mission seeks to preserve, curate, augment, and promote historical digital artifacts from the metaverse beginning with the virtual world of Cryptovoxels.New here?

They offer a wide range of plugins to import models directly into your favorite 3D software easily.Importing districts from a Sketchfab importer: https://sketchfab.com/importersWith the blender plugin you can search for cryptovoxels 2019 and quickly import chunks from the 12-13-2019 dataset into your project.You can import as much or as little as you want. I labeled the dataset with the year it was taken as a tag for optimizing search.We are planning to take another 3D snapshot of the world on the 3rd anniversary of the last one, 12-13-2022, and run a buildathon alongside. Join the M3 discord if you want to help us plan..OptimizationThe biggest district in the collection is Frankfurt comes in at a whopping 150mb and 1.7M triangles. I took a double look when I was able to compress this model down to 3.3mb via Draco using http://gltf.report. I could still could shave 30% with gzip as well, making the final compressed version only 2.1mb. To compare with a different method, Meshopt compression only went to 25mb and broke the collision in Hyperfy.Comparing uncompressed to Draco and meshopt file size for Frankfurt district, the biggest district in Origin CityThe only complaint I heard about Draco is that the size of the WASM library decoder may outweigh size savings for geometry <1MB. If that's all then no biggie - the size difference between uncompressed and other forms of compression like meshopt is substantial in our case.Comparing compressed file size for the entire Origin City dataset, Draco is 32.1 MB compared to 1.43 GB uncompressedUse CasesDigital preservationglTF 2.0 is an international standard file format for 3D modelsSnapshot virtual worlds like the Internet Archive Wayback machineCreate living museumsRecreate CV as it were during a period in timeAlternate realitiesSee how Voxels might look with diff skyboxes or weatherSandbox for rapid prototypingExperiment and use to pitch featuresGood ideas can make their way back to mainHome space decoration (scale to tabletop size)Mixed media art projects / 3D renderingFinal ThoughtsI want to close this with various ideas that have inspired me during this part.
