This can be used in case device creation failed and a rtcErrorFunction could not be set up for this purpose. - Added the API function rtcGetErrorString which returns a string representation of a given RTCError error code. This is purely meant for convenient error information reporting on the user application side. +- Performance improvements on GPU for the one level instancing case (RTC_MAX_INSTANCE_LEVEL_COUNT 1). +- Reduced the number of unneccessary GPU-CPU USM back-migrations which can increase build performance for scene with many instances on GPU. +- Started adding public CI tests for streamlining integration of external pull requests. +- Work-around for problem with unsigned Windows binaries. ### Embree 4.3.2 - Embree now uses level zero raytracing extension to build BVH which enables forward-compatibility. On Linux, the package intel-level-zero-gpu-raytracing has to be installed in addition to the other packages listed here [https://dgpu-docs.intel.com/](https://dgpu-docs.intel.com/). diff --git a/README.md b/README.md index 0fd0920d72..cdf581be58 100644 --- a/README.md +++ b/README.md @@ -1,4 +1,4 @@ -% Embree: High Performance Ray Tracing Kernels 4.3.2 +% Embree: High Performance Ray Tracing Kernels 4.3.3 % Intel Corporation Intel® Embree Overview @@ -100,7 +100,7 @@ Windows Installation -------------------- A pre-built version of Embree for Windows is provided as a ZIP archive -[embree-4.3.2.x64.windows.zip](https://github.com/embree/embree/releases/download/v4.3.2/embree-4.3.2.x64.windows.zip).
