The disclosed implementations describe techniques and workflows for a computer graphics (CG) animation system. In some implementations, systems and methods are disclosed for representing scene composition and performing underlying computations within a unified generalized expression graph with cycles. Disclosed are natural mechanisms for level-of-detail control, adaptive caching, minimal re-compute, lazy evaluation, predictive computation and progressive refinement. The disclosed implementations provide real-time guarantees for minimum graphics frame rates and support automatic tradeoffs between rendering quality, accuracy and speed. The disclosed implementations also support new workflow paradigms, including layered animation and motion- path manipulation of articulated bodies.

L'invention concerne des techniques de transitique pour un système d'animation graphique informatique (CG). Dans quelques modes de réalisation, des systèmes et des procédés servent à représenter une composition de scène et à exécuter des calculs sous-jacents à l'intérieur d'un graphique d'expression unifié et généralisé comportant des cycles. Elle concerne des mécanismes naturels de contrôle de niveau de détail, de mise en antémémoire adaptative, de recours minimum à de nouveaux calculs, d'évaluation paresseuse, de calcul prédictif et de raffinement progressif. Ces modes de réalisation fournissent des garanties en temps réel de fréquences de trames graphiques minima et d'options automatiques de support entre la qualité du rendu, sa précision et sa vitesse. Elle supporte également de nouveaux paradigmes de flux de travail, y compris l'animation stratifiée et la manipulation de la trajectoire de mouvement de corps articulés.
