Our 3D re­pos­it­ory sits atop of a NoSQL Mon­goDB in the cloud. Each 3D scene com­pon­ent is stored and trans­mit­ted as a bin­ary blob.


A built-​​in cross-​​platform 3D Diff tool sup­ports visual dif­fer­en­cing and mer­ging of 3D mod­els re­volu­tion­al­ising col­lab­or­at­ive mod­el­ling.


The plat­form can be eas­ily ex­ten­ded and cus­tom­ised. We already sup­port 42 dif­fer­ent 3D file formats and are work­ing on more.
