A thread for refreshing our memories about outlandish claims, great announcements we never heard about again, vaporware, etc ...
I'll start with one,
what happened to Euclideon, a company that claimed to be able to render unlimited detail on current hardware and they were not voxel or point clouds. See their video:
Nowadays they seem to focus on the medical market with the same kind of videos and still have no game out. At least they acknowledge that what they are doing is rendering point-cloud data, but they still have some amazing claims in their new videos about being able to process and compress the data.
