cl_khr_3d_image_writes - Extension to enable writes to 3D image memory objects. #pragma OPENCL EXTENSION cl_khr_3d_image_writes : enable
OpenCL supports 2D image memory objects that can be read or written by kernels. Reads and writes to the same 2D image memory object are not supported in a kernel. OpenCL also supports reads to 3D image memory objects in kernels. Writes to a 3D image memory object are not supported unless the cl_khr_3d_image_writes extension is implemented. Reads and writes to the same 3D image memory object are not allowed in a kernel. An application that wants to use this extension to write to 3D image memory objects will need to include the #pragma OPENCL EXTENSION cl_khr_3d_image_writes : enable directive in the OpenCL program source. The write_image3d(3clc) are implemented by the cl_khr_3d_image_writes extension.
