Nuke The City

I rendered this video frame-by-frame using my custom NORI renderer for my course project at the University of Zaragoza in Modelling and Simulation of Appearance.

The volumetric media is loaded using OpenVDB, including temperature and density fields.

The emission and color of the medium are inferred using a logarithmic temperature scale.

To make emission more prominent, Next Event Estimation (NEE) is used by inserting point lights at the centers of octree leaf nodes. The octree provides a tight spatial bounding structure for efficient volumetric rendering.
