Abstract

fetched live from OpenAlex

Artistic rendering is an important research area in Computer Graphics, yet relatively little attention has been paid to the projective properties of computer generated scenes. Motivated by the surreal storyboard of an animation in production---Ryan---this paper describes interactive techniques to control and render scenes using nonlinear projections. The paper makes three contributions. First, we present a novel approach that distorts scene geometry such that when viewed through a standard linear perspective camera, the scene appears nonlinearly projected. Second, we describe a framework for the interactive authoring of nonlinear projections defined as a combination of scene constraints and a number of linear perspective cameras. Finally, we address the impact of nonlinear projection on rendering and explore various illumination effects. These techniques, implemented in Maya and used in the production of the animation Ryan, demonstrate how geometric and rendering effects resulting from nonlinear projections can be seamlessly introduced into current production pipelines.

Not 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.
