Hey everyone!
I’m excited to share the 3d-tiles-renderer project that I worked on and open sourced years ago at NASA JPL. This renderer has been used in recent Mars missions on both the Perseverance and Curiosity rovers to display 3D tiles datasets, which include data from orbiters and rovers for contextual landscape and environment visualizations.
For those unfamiliar, 3D tiles is a format designed to enable progressive and scalable loading of large datasets—like cities or Mars topological maps—by only displaying a minimal amount of data based on certain error metrics. This is achieved by creating various levels of tile LoDs arranged in a bounding volume hierarchy until full detail is reached at the leaves.
You can explore several demos in the repository, including one that renders a Dingo Gap data set from Curiosity. The project is also integrated into the Explore with Perseverance Experience to showcase mission terrain.

3D Tiles Renderer for Mars Mission Visualizations
The 3D-tiles-renderer project is an impressive open-source contribution from NASA JPL that enables visualization of large 3D datasets from Mars missions. This technology has been used in both the Perseverance and Curiosity rover missions to display contextual landscape data.
Key Features
- Progressive Loading: The 3D tiles format allows for scalable loading of massive datasets like Mars topological maps
- Efficient Rendering: Only displays minimal necessary data based on error metrics
- Level of Detail (LoD): Uses a bounding volume hierarchy with varying detail levels
- Real Mission Application: Integrated into actual Mars mission visualization tools
Available Demos
You can explore the technology through several demos in the repository:
- The Dingo Gap dataset from the Curiosity rover
- Integration with the Explore with Perseverance Experience website
The visualizations show detailed Martian terrain that helps provide context for rover operations and scientific analysis.
This project demonstrates how advanced 3D rendering techniques can be applied to space exploration data visualization, making complex topographical information more accessible and useful for mission operations.
