Brayns
A large-scale scientific visualization platform for interactive ray-tracing of neurons and other biological data.
What is Brayns?
Brayns is a large-scale scientific visualization platform that performs interactive ray-tracing of complex biological data, such as neuronal circuits and molecules. It is built on Intel OSPRay for CPU-based rendering, allowing researchers to visualize massive datasets with high fidelity. The platform addresses the need for detailed, real-time exploration of neuroscientific and biomedical structures.
Neuroscientists, bioinformaticians, and researchers working with large-scale biological data who require high-performance visualization tools. It is also suited for developers in scientific computing needing extensible visualization backends.
Brayns offers a modular, plugin-based architecture that simplifies adding new visualization use cases while maintaining core stability. Its CPU ray-tracing approach leverages hardware efficiently, providing detailed rendering without requiring specialized GPU setups, and it supports remote streaming for collaborative research.

Pros & Cons
Pros
Leverages Intel OSPRay for detailed ray-tracing without GPU dependency, enabling high-quality visualization on hardware where GPUs are limited, as emphasized in the README's focus on hardware efficiency.
Core functionality is extensible via independent plugins like CircuitExplorer, allowing customization for new scientific use cases without compromising stability, per the README's design philosophy.
The braynsService backend streams rendered images over the internet, facilitating collaborative research and access from thin clients, as described in the key features.
Includes plugins for neuroscience-specific formats such as NRRD volumes with AtlasExplorer and PDB files with MoleculeExplorer, making it ideal for biological data visualization.
Available as a Docker image on Docker Hub, simplifying deployment and ensuring consistency across environments, with support for latest commits and tagged releases.
Cons
Requires custom OSPRay 2.10.5 and multiple system dependencies like HDF5 and GCC 12.1+, making setup challenging and time-consuming, as detailed in the build instructions.
Only tested and supported on Linux distributions like Ubuntu and RHEL, with no native support for Windows or macOS, excluding teams without Linux infrastructure.
While build steps are provided, comprehensive guides for developing custom plugins or using the JSON-RPC API are minimal, relying on external Python client documentation without in-depth tutorials.
CPU-based ray-tracing may be slower than GPU alternatives for large datasets, and the README lacks performance benchmarks, potentially limiting use in real-time scenarios.
