The most basic data type. An element represents one cell of a memory allocation. * Element is the basic data type of Renderscript. An element can be of two forms: Basic elements or Complex forms. * Examples of basic elements are:
*Complex elements contain a list of sub-elements and names that * represents a structure of data. The fields can be accessed by name * from a script or shader. The memory layout is defined and ordered. Data * alignment is determined by the most basic primitive type. i.e. a float4 * vector will be aligned to sizeof(float) and not sizeof(float4). The * ordering of elements in memory will be the order in which they were added * with each component aligned as necessary. No re-ordering will be done.
* *The primary source of elements are from scripts. A script that exports a * bind point for a data structure generates a Renderscript element to represent the * data exported by the script. The other common source of elements is from bitmap formats.
