|

* <p>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. </p>
|
||||
* <p>
|
||||
* 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.
|
||||
* </p>
|
||||
* <p>
|
||||
* Parts of the mesh can be rendered with either explicit
|
||||
* index sets or primitive types.
