Hello! I’m looking for file format specifications for usda and usdc. From reading the USD documentation, I can mostly infer the usda file format, but I’m sure I’m missing some details. I see how most “USD concepts” map to the file format through the examples, but I would really like to see a formal specification if such a thing exists.
I haven’t found anything (other than reading source code) to grok the usdc file format.
For usda, I’m looking for essentially a “language specification”. Something like:
- starts with
- Followed by a metdata block
- Followed by a sequence of definitions
A metdata block is is a literal
( followed by…
A definitions is a literal
def followed by …
And similarly for usdc something which indicates how data is packed, encoded, framed, etc.
Thanks in advance!
