+# Getting Started Sample for Intel oneAPI Rendering Toolkit: Intel OSPRay
+
+Intel OSPRay is an open source, scalable, and portable ray tracing engine for high-performance, high-fidelity visualization. Easily build applications that use ray tracing based rendering for both surface and volume-based visualizations. OSPRay builds on top of Embree, Open VKL, and Open Image Denoise.

+
+
+## Purpose
+
+- This getting started sample program, `ospTutorialCpp`, renders two conjoined triangles with the [OSPRay API](https://www.ospray.org/documentation.html).
+- Two renders of the triangles are written to .ppm image files on disk. The first image is rendered with one accumulation. The second image is rendered with ten accumulations.
+
+## Key Implementation details
+
+- The noise visible with only one accumulation is a common artifact of Monte Carlo based sampling. Notice the noise reduction (convergence) apparent in the image with ten accumulations.
+- This sample uses the C++ API wrapper for the OSPRay API. The C++ API wrapper definitions are accessed via ospray_cpp.h. A pure C99 version of this tutorial is available on the [OSPRay github portal](https://github.com/ospray/ospray).
+- This sample defines triangle vertex and color data using vector types found in the Render Kit rkcommon support library. These types can be swapped out for vector types found in the OpenGL* Math (GLM) library. An alternate, GLM, implementation of the sample is available for advanced users on the [OSPRay github portal](https://github.com/ospray/ospray).
+- This sample renders single images. OSPRay is also used heavily in interactive rendering environments. Advanced users can see `ospExamples` on the [OSPRay github portal](https://github.com/ospray/ospray) and the [Intel OSPRay Studio](https://github.com/ospray/ospray_studio) showcase interactive application.
