Detailed Description

Use texture memory for optimized read only cache access.

This represents a view on the memory owned by a CUDA array. Thus you can first create a CUDA array (cuda::array_t) and subsequently create a texture_view from it. In CUDA kernels elements of the array can be accessed with e.g. float val = tex3D<float>(tex_obj, x, y, z);, where tex_obj can be obtained by the member function get() of this class.

See also the following sections in the CUDA programming guide:

Note
texture_view's are essentially owning - the view is a resource the CUDA runtime creates for you, which then needs to be freed.

The documentation for this class was generated from the following files:
