<p>RenderScript exposes a set of compute APIs that you can use to do intensive computational operations.
|
||
|
|
You can use the compute APIs in the context of a graphics RenderScript such as calculating the
|
||
|
|
transformation of many geometric objects in a scene. You can also create a standalone compute RenderScript that does not
|
||
|
|
draw anything to the screen such as bitmap image processing for a photo editor application.
|
||
|
|
The RenderScript compute APIs are mainly defined in the <code>rs_cl.rsh</code> header</p>
|
||
|
|
|
||
|
|
<p>Compute RenderScripts are simpler to setup and implement as there is no graphics rendering involved.
|
||
|
|
You can offload computational aspects of your application to RenderScript by creating a native RenderScript
|
||
|
|
file (.rs) and using the generated reflected layer class to call functions in the <code>.rs</code> file.
