Path Tracing

About

Provides a comprehensive framework for reverse-engineering programmatically-generated ray-traced images, focusing on extracting scene parameters like camera position, geometry, and lighting from a target image. The skill guides developers through a four-phase approach involving systematic pixel analysis, fast iteration with downscaled renders, component-specific verification, and final high-resolution validation. It is particularly useful for tasks requiring extremely high similarity scores (0.99+) and includes technical guidance on avoiding common pitfalls like gradient inversion or incorrect runtime estimation.
