Python for scene and model description for computer graphics
Bibliographic record
Abstract
Python is a general purpose language for use in many applications. In this work we have used Python as the input scene and model description language for a suite of rendering and modeling tools developed at the University of Calgary. Little languages have been used extensively in this arena. Most notably Lua [7, 5], and the Renderman Languages [16]. Python has been used at the University of Calgary for the construction of very complex models. We describe a set of software tools for interactive rendering of models and the description of scenes built up from these models. We also describe a parallel rendering system all based on Python. Parallel renderings are computed on a 30 node distributed memory computer, a discussion of using MPI [6] in concert with Python is given. 1

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
