Interactive Rendering on CPU or GPU

OSPRay features scalable CPU and GPU rendering capabilities geared toward Scientific Visualization applications. Advanced shading effects such as ambient occlusion, shadows, and transparency can be rendered interactively to enable new insights into huge data.

Global Illumination

OSPRay includes a path tracer capable of interactively rendering photorealistic global illumination with phyiscally-based materials.

Volume Rendering

OSPRay supports high-fidelity, interactive direct volume rendering with a number of state of the art visualization features.

MPI Distributed

Run on large scale distributed-memory systems with high-performance MPI backends to both decrease render time and increase total scene size.

Industry Adoption

OSPRay is directly integrated into ParaView 5.x. Implementations for VisIt, VMD, and other popular tools have also freely available.

Open Source

OSPRay is Open Sourced under the Apache 2.0 license.
