Title:
- Modular Scene Filtering via the Pixar Hydra 2.0 Architecture

Abstract:
Pixar’s Hydra project began as an abstract scene interface to an OpenGL-based renderer intended for interactive viewports across multiple applications. As the project added integrations with other renderers (including path tracers), it became clear that it needed a richer scene interface to convey a broader set of renderer features, as well as a more structured and modular way to resolve the scene into rendering primitives.
We’ll discuss the Hydra 2.0 architecture that was developed to address this problem, with examples from two scene filtering cases:
