↳ | android.renderscript.Mesh |
This class is a container for geometric data displayed with Renderscript. Internally, a mesh is a collection of allocations that represent vertex data (positions, normals, texture coordinates) and index data such as triangles and lines.
Vertex data could either be interleaved within one allocation that is provided separately, as multiple allocation objects, or done as a combination of both. When a vertex channel name matches an input in the vertex program, Renderscript automatically connects the two together.
Parts of the mesh can be rendered with either explicit index sets or primitive types.

destroy disconnects the object from the native object effectivly rendering this java object dead. The primary use is to force immediate cleanup of resources when its believed the GC will not respond quickly enough.

setName assigns a name to an object. This object can later be looked up by this name. This name will also be retained if the object is written to an A3D file.
name | The name to assign to the object. |

Called before the object's memory is reclaimed by the VM. This can only happen once the garbage collector has detected that the object is no longer reachable by any thread of the running application.
The method can be used to free system resources or perform other cleanup
before the object is garbage collected. The default implementation of the
method is empty, which is also expected by the VM, but subclasses can
override finalize()
as required. Uncaught exceptions which are
thrown during the execution of this method cause it to terminate
immediately but are otherwise ignored.
Note that the VM does guarantee that finalize()
is called at most
once for any object, but it doesn't guarantee when (if at all) finalize()
will be called. For example, object B's finalize()
can delay the execution of object A's finalize()
method and
therefore it can delay the reclamation of A's memory. To be safe, use a
ReferenceQueue
, because it provides more control
over the way the VM deals with references during garbage collection.
