# Getting Started Sample for Intel® oneAPI Rendering Toolkit (Render Kit): Intel® Embree

Intel® Embree is a collection of high-performance ray tracing kernels.
Improve performance of photo-realistic rendering applications by using
performance optimized ray-tracing kernels.
Intel Embree is a library of high-performance ray tracing kernels. Improve performance of photo-realistic rendering applications with Intel Embree.

| Minimum Requirements | Description
|:--- |:---
| OS | Linux* Ubuntu* 18.04 <br>CentOS 8 (or compatible) <br>Windows* 10 <br>macOS 10.15+
| Hardware | Intel 64 Penryn or newer with SSE4.1 extensions; ARM64 with NEON extensions <br>(Optimized requirements: Intel 64 Skylake or newer with AVX512 extentions, ARM64 with NEON extensions)
| Compiler Toolchain | Windows: MSVS 2019 with Windows SDK and CMake*; Other platforms: C++11 compiler, a C99 compiler (for example gcc/c++/clang), and CMake*
| Libraries | Install Intel&reg; oneAPI Rendering Toolkit (Render Kit), including Embree
## Versions

| Objective | Description
|:--- |:---
| What you will learn | How to build and run a basic sample program using the Embree API from the Render Kit.
| Time to complete | 5 minutes
1. [CPU](./cpu/) - for Intel64 (x86-64) Host)
- This version of the `minimal` program uses a C++11 (or C99) compiler to target the host processor.
2. [GPU](./gpu/) - for Intel&reg; Arc&trade; hardware (Xe-HPG))
- This `minimal_sycl` program uses Intel&reg; oneAPI DPC/C++ Compiler and SYCL* Runtimes to target the GPU.

## Purpose

This sample program, `minimal`, performs two ray to triangle intersect tests
with the Intel&reg; Embree API. One test is successful, while the other test is
a miss. Output is written to the console (stdout).

## Key Implementation Details

This source code is constructed to build with a C++ or a C compiler.

## Build and Run

### Windows

1. Run a new **x64 Native Tools Command Prompt for MSVS 2019**.

```
call <path-to-oneapi-folder>\setvars.bat
cd <path-to-oneAPI-samples>\RenderingToolkit\02_embree_gsg
mkdir build
cd build
cmake ..
cmake --build . --config Release
cd Release
minimal.exe
```

2. Review the terminal output (stdout).


### Linux and macOS

1. Start a new Terminal session.
```
source <path-to-oneapi-folder>/setvars.sh
cd <path-to-oneAPI-samples>/RenderingToolkit/02_embree_gsg
mkdir build
cd build
cmake ..
cmake --build .
./minimal
```
2. Review the terminal output (stdout).
