This folder contains sources of the Embree tutorials for illustration
purposes of the API. Follow the next sections to compile the
tutorials.
Compilation under Windows using SYCL
-------------------------------------
Install one of the SYCL compilers supported by Embree, see section
[Compiling Embree / Windows SYCL Compilation] of the Embree
documentation.
Then open some "x64 Native Tools Command Prompt" of Visual Studio and
execute the following line which properly configures the environment to
use the DPC++ compiler:
set "DPCPP_DIR=path_to_dpcpp_compiler"
set "PATH=%DPCPP_DIR%\bin;%PATH%"
set "PATH=%DPCPP_DIR%\lib;%PATH%"
set "CPATH=%DPCPP_DIR%\include;%CPATH%"
set "INCLUDE=%DPCPP_DIR%\include;%INCLUDE%"
set "LIB=%DPCPP_DIR%\lib;%LIB%"
Now download and unpack some recent TBB version for Windows, e.g. oneTBB 2021.2.0:
https://github.com/oneapi-src/oneTBB/releases/download/v2021.2.0/oneapi-tbb-2021.2.0-win.zip
To compile tutorials contained in this folder first create and enter a
build folder inside the tutorial you want to compile. E.g. for the
minimal tutorial execute:
cd minimal
mkdir build
cd build
Then configure the tutorial you would like to compile by pointing to
the Embree and TBB installation on your system.
cmake -G Ninja
-D CMAKE_CXX_COMPILER=clang++
-D CMAKE_C_COMPILER=clang
-D CMAKE_BUILD_TYPE=Release
-D embree_DIR=%cd%\..\..\..\lib\cmake\embree-4.3.3\
-D TBB_DIR=path_to_tbb\oneapi-tbb-2021.2.0\lib\cmake\tbb ..
Now you can build the tutorial:
cmake --build .
In order to run the tutorial you have to set the PATH to the bin
folder in order to find the Embree DLL:
set PATH=%cd%\..\..\..\bin;%PATH%
Now you can run the tutorial:
.\minimal.exe
.\minimal_sycl.exe
Compilation under Linux using SYCL
-----------------------------------
Install one of the SYCL compilers supported by Embree, see section
[Compiling Embree / Linux SYCL Compilation] of the Embree
documentation.
To properly configure your environment, you have to source the
`startup.sh` of the unpacked DPC++ compiler:
source dpcpp_compiler/startup.sh
Now download and unpack some recent TBB version for Linux, e.g. oneTBB 2021.2.0:
wget https://github.com/oneapi-src/oneTBB/releases/download/v2021.2.0/oneapi-tbb-2021.2.0-lin.tgz
tar xzf oneapi-tbb-2021.2.0-lin.tgz
To compile tutorials contained in this folder first create and enter a
build folder inside the tutorial you want to compile. E.g. for the
minimal tutorial execute:
cd minimal
mkdir build
cd build
Then configure the tutorial you would like to compile by pointing to
the Embree and TBB installation on your system.
cmake -D CMAKE_BUILD_TYPE=Release \
-D CMAKE_CXX_COMPILER=clang++ \
-D CMAKE_C_COMPILER=clang \
-D embree_DIR=`pwd`/../../../lib/cmake/embree-4.3.3/ \
-D TBB_DIR=path_to_tbb/oneapi-tbb-2021.2.0/lib/cmake/tbb/ ..
Now you can build the tutorial:
cmake --build .
Now you can run the tutorial:
./minimal
./minimal_sycl
