I think it's safe to say that these were all collected at a time when people were not doing any diligence as far as documenting the provenance of the test images and ensuring that they had permissions from the owners.
quad and strike are from Pixar (quad was just a test image for their renderer, strike is a small version of the image on the cover of the book "The RenderMan Companion"). jello is from a SIGGRAPH 1987 paper by Paul Heckbert. office is an image I think I recognize from an early computer graphics research paper, but I can't quite remember which one. oxford is just a screen shot of the process meter on an SGI, I think that one can surely be said not to contain anybody's IP. the photographs obviously belong to somebody, but I don't know who. I don't know if it was Sam or not who actually took or owned them. > On Jun 19, 2022, at 12:00 PM, [email protected] wrote: > >> >> Anyone know what the origin and purpose of these images is (or was)?
