Do you have any names you would recommend?

I am not in the field, but I am working on multi-materials architecture designs and one of the questions how can I started design such system to come up with new possibilities of architecture and new geometries. While reading the abstract in that paper it mentions "novel object synthesis" what this mean actually?

I am also struggling to understand what are the possibilities behind the explosion of diffusion models beyond art, sorry if that sound ignorant but I want to understand and deploy this in my work hopefully.
