embree-api

Embree2 compatible API for NanoRT

Drop-in replacement of raytracing engine with Embree API for cross-platform support(e.g. raytracing on ARM, PowerPC)

Version

Based on Embree2 2.17.0 header.

Status

Minimum and experimental.

Triangle + single ray intersection only.

Coordinates

• Right-handed
• Geometric normal defined as CCW

How to use

Simply copy embree2 header files(include/embree2/), nanort.h(../../), nanosg.h(../nanosg/) and nanort-embree.cc to your project.

Notes

Current implementation does not consider calling Embree API from multi-threaded context. Application must care of calling Embree API with proper locking(except for rtcIntersect)

TODO

• Curve/hair
• Subdivision surface
• Motion blur
• Instanciation
• Stream intersection API
• Ray stream API
• Multi-threading support.
• DLL build of nanort-embree module.
