static TypedWritable *const | Null = nullptr |
This class defines the physical layout of the vertex data stored within a Geom.
The layout consists of a list of named columns, each of which has a numeric type and a size.
The columns are typically interleaved within a single array, but they may also be distributed among multiple different arrays; at the extreme, each column may be alone within its own array (which amounts to a parallel-array definition).
Thus, a GeomVertexFormat is really a list of GeomVertexArrayFormats, each of which contains a list of columns. However, a particular column name should not appear more than once in the format, even between different arrays.
There are a handful of standard pre-defined GeomVertexFormat objects, or you may define your own as needed. You may record any combination of standard and/or user-defined columns in your custom GeomVertexFormat constructions.
