Rendered with Huira

Each of these comes from one of the quick-start examples, in Python and C++. Select one to see how it was made.

The Gateway NASA's model of the Gateway, loaded from glTF and path traced. Motion blur The Gateway spinning once a second, over a 16 ms exposure. Clouds and atmosphere A cloud shell over the Earth, and an atmosphere that scatters light. City lights The Earth's night side, with emissive city lights. Orion Stars from the Tycho-2 catalog. The Pleiades Diffraction, scattered light and distortion in the camera's optics. Planetshine A satellite's night side, lit by the planet below it. Truth data Surface normals, one of the truth images rendered with each picture.

Quick Start

Examples that walk through Huira one feature at a time, each building on the ones before it. Every example comes in Python and C++, lists the data it needs, and shows what it renders.

Validation

Huira's renders compared against real flight imagery, so you can see how closely it reproduces what a spacecraft's camera saw.
