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-@EMBREE_VERSION@\
|
|
-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-@EMBREE_VERSION@/ \
|
|
-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
|
|
|
