However, what you can do is just create a new ISPC struct that contains the Embree ray as first argument (e.g.&nbsp;struct ExtendedRay { RTCRay ray; MyData* data; }) and do proper casting.</P> <P>2) If I understand correct your questions targets on using the C++ and ISPC version of Embree in the same program? This is supported, the only thing to be carefull is to set RTC_INTERSECT1/4/8/16 flags in case one creates the scene on the C++ side and wants to call the rtcIntersect function in ISPC later on that scene.</P> Wed, 22 Oct 2014 06:22:58 GMT SvenW_Intel 2014-10-22T06:22:58Z https://community.intel.com/t5/Intel-Embree-Ray-Tracing-Kernels/Integration-questions/m-p/1031251#M420 <P>Hi All</P> <P>1) I'm passing my data to rays as following (pseudocode)</P> <P>struct MyRay : public RTCRay {</P> <P>&nbsp;MyData * data;</P> <P>};</P> <P>It works fine but how to do same with ispc where ray is "varying"?</P> <P>2) For ispc I've built object files for <EM>rtcore_ispc.ispc</EM> and <EM>myfile.ispc</EM> that contains only one export function with rtcInit(). For all others (creating scene, set callbacks, cast rays) I use same C++ code as without ispc. Is it correct?</P> <P>Thanks</P> Tue, 21 Oct 2014 16:22:39 GMT https://community.intel.com/t5/Intel-Embree-Ray-Tracing-Kernels/Integration-questions/m-p/1031251#M420 Igor_Igor 2014-10-21T16:22:39Z https://community.intel.com/t5/Intel-Embree-Ray-Tracing-Kernels/Integration-questions/m-p/1031252#M421 <P>1) ISPC does not support classes, thus you cannot derive from the Embree ray this way.
