Embree: Photo-Realistic Ray Tracing Kernels

Procedural geometry possibility with Shape class in raytracer


  I am exploring the possibility of injecting geometry procedurally [http://renderman.pixar.com/view/appnote23] to the Embree RayTracer.

  Is the Shape class the place to start ?

  Does the ray tracer request geometry bucket by bucket so as to conserve/control memory usage ?


Embree 2.0 to be released during Siggraph 2013

Based on Embree's success on Intel Xeon platforms we are proud to announce the release of Embree 2.0 with support for Xeon Phi during the annual ACM Siggraph 2013 Conference in Anaheim, CA. Embree 2.0 will be presented on July 25th from 3:45 to 5:15 in the Convention Center in Anaheim in Ballroom D, and will be released on embree.github.com shortly thereafter.

Bug when inverting embree::OrthonormalSpace3f ?


I think I found a bug.
When calculating the inverse of an instance of embree::OrthonormalSpace3f via rcp(..) the resulting translation is wrong. I tracked down the problem to line 86 in common/math/affinespace.h:

  template<typename L> __forceinline AffineSpaceT<L>        rcp( const AffineSpaceT<L>& a ) { L il = rcp(a.l); return AffineSpaceT<L>(il,-il*a.p); }

Reload 3D Model to the existing scene

Hi Everyone,
I have developed an application which uses the method below to load and display a 3d model. Now when I reload the new 3d model using same method, then the application exits. Please someone guide me in this regards so I can reload the 3D model.Thanks.

g_device = Device::rtCreateDevice("default",g_numThreads);
g_pathTOECSFile = FileName(pathToECSFile);
g_pathToModelFile = g_pathTOECSFile.path() + getModelFileName(pathToECSFile);

rendering engine - material configuration


First, thanks so much for releasing such a powerfull library with such an easy to use API.

I have no experience at all with raytracers and despite all the warnings, so far I've found the rendering engine to be complete enough to achieve amazing results really fast. I made a little OpenFrameworks addon that allows to render OF geometries with the interactive renderer : https://github.com/kikko/ofxEmbree

Embree in Action

First I want to express our gratitude for the embree team at Intel for the great software they are making.

At SimLab Soft we utilized the power of embree in the new SimLab Composer 2014, and the result is a real time rendering capability that makes user happy. Following is a screen shot of the embree real time view inside SimLab Composer 2014.
