A texture is a data aggregate on an accelerator_view in the extent domain. It is a collection of variables, one for each element in an extent domain. Each variable holds a value corresponding to C++ primitive type (unsigned int, int, float, double), a scalar type (norm, or unorm), or a short vector type.

Parameters

_Value_type
The type of the elements in the texture.
_Rank
The rank of the texture.
