/**
|
||
|
* This defines the actual numeric vertex data stored in a Geom, in the
|
||
|
* structure defined by a particular GeomVertexFormat object.
|
||
|
*
|
||
|
* The data consists of one or more arrays, each of which in turn consists of
|
||
|
* a series of rows, one per vertex. All arrays should have the same number
|
||
|
* of rows; each vertex is defined by the column data from a particular row
|
||
|
* across all arrays.
|
||
|
*
|
||
|
* Often, there will be only one array per Geom, and the various columns
|
||
|
* defined in the GeomVertexFormat will be interleaved within that array.
|
||
|
* However, it is also possible to have multiple different arrays, with a
|
||
|
* certain subset of the total columns defined in each array.
|
||
|
*
|
||
|
* However the data is distributed, the effect is of a single table of
|
||
|
* vertices, where each vertex is represented by one row of the table.
|
||
|
*
|
||
|
* In general, application code should not attempt to directly manipulate the
|
||
|
* vertex data through this structure; instead, use the GeomVertexReader,
|
||
|
* GeomVertexWriter, and GeomVertexRewriter objects to read and write vertex
|
||
|
* data at a high level.
