Anyone can help me, which lib missing? Error LNK2019 unresolved external symbol "public: bool __cdecl embree::Geometry::pointQuery(struct embree::PointQueryK<1> ,struct embree::PointQueryContext )" (?pointQuery@Geometry@embree@@QEAA_NPEAU?$PointQueryK@$00@2@PEAUPointQueryContext@2@@Z)，function"public: static bool __cdecl embree::avx2::ObjectIntersector1<1>::pointQuery(struct embree::PointQueryK<1> ,struct embree::PointQueryContext ,struct embree::Object const &)" (?pointQuery@?$ObjectIntersector1@$00@avx2@embree@@SA_NPEAU?$PointQueryK@$00@3@PEAUPointQueryContext@3@AEBUObject@3@@Z)

Could you explain what you are trying to do? Do you compile Embree? If so which config did you setup in cmake and which Embree version are you using?

I am grateful for your response. I build which this command

cmake -G "Visual Studio 17 2022" -D CMAKE_BUILD_TYPE=Debug -D EMBREE_LIBRARY_NAME=frontface4 -D EMBREE_BACKFACE_CULLING=ON -D EMBREE_BACKFACE_CULLING_CURVES=ON -D EMBREE_BACKFACE_CULLING_SPHERES=ON -D EMBREE_MAX_ISA=AVX2 -D EMBREE_ISA_AVX2=ON -D TBB_ROOT="C:\Program Files (x86)\Intel\oneAPI\tbb\2021.9.0\lib\cmake\tbb" -D CMAKE_INSTALL_PREFIX="F:/DevTools/embree4-frontface-Debug" ..

I can access BVH, but the intersect function can't complie embree::isa::BVH4Triangle4Intersector1Moeller().intersect(&(((Accel*)scene)->intersectors), rayhit, NULL);

You write that you can access the BVH, does that mean the above Embree compilation succeeds?

I just tried your combination of cmake flags under Linux and there it compiles fine. You do not need the EMBREE_ISA_AVX2=ON option, EMBREE_MAX_ISA=AVX2 already enabled AVX2.

Are you trying to additionally compile the embree::isa::BVH4Triangle4Intersector1Moeller().intersect(&(((Accel*)scene)->intersectors), rayhit, NULL); inside your application?

Please do use Embree through its API as described in an example here:
