HDR Tone Mapping for Post Processing Using OpenCL™ Technology

Published:05/16/2014

Features and Description

The Tone Mapping sample demonstrates how to use high dynamic range (HDR) rendering with tone mapping effect with the OpenCL™ technology.

It also demonstrates a CPU-optimized implementation of the tone mapping effect, showing how to:

Implement calculation kernels using OpenCL C99
Parallelize the kernels by running several work-groups in parallel
Organize data exchange between the host and the OpenCL device
Store the final image on the hard drive.

Supported Devices: CPU, Intel® Processor Graphics, Intel® Xeon Phi™ coprocessor
Supported OS: Windows* OS
Complexity Level: Novice

For more information about the sample refer to the sample documentation inside the package.

Product and Performance Information

¹

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
