## The Open, Scalable, and Portable Ray Tracing Engine

### Render massive scenes interactively

Disney's Moana Island Scene: over 15 billion instanced primitives+volume at interactive rates

### Photorealism

Physically-based shading and lighting

### Feature rich, large-scale volume visualization

Richtmyer–meshkov volume shown with shadows and ambient occlusion

### USD Hydra Integration

Gramophone rendered in Pixar's usdview

### Integrations in VTK, ParaView, VisIt, and more

DKRZ weather data rendered with shadows inside ParaView

### Directly render unstructured and AMR volumes

AMR volume rendered without resampling inside ParaView

## 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.
