|
|
|
* The most important function in this fill is \c fill_array_info_cache.
|
|
|
|
* The \c array_state_vector contains a cache of the ARRAY_INFO data sent
|
|
|
|
* in the DrawArrays protocol. Certain operations, such as enabling or
|
|
|
|
* disabling an array, can invalidate this cache. \c fill_array_info_cache
|
|
|
|
* fills-in this data. Additionally, it examines the enabled state and
|
|
|
|
* other factors to determine what "version" of DrawArrays protocoal can be
|
|
|
|
* used.

|
|
|
* Current, only two versions of DrawArrays protocol are implemented. The
|
|
|
|
* first version is the "none" protocol. This is the fallback when the
|
|
|
|
* server does not support GL 1.1 / EXT_vertex_arrays. It is implemented
|
|
|
|
* by sending batches of immediate mode commands that are equivalent to the
|
|
|
|
* DrawArrays protocol.
|
|
|
|
*
|
|
|
|
* The other protocol that is currently implemented is the "old" protocol.
|
|
|
|
* This is the GL 1.1 DrawArrays protocol. The only difference between GL
|
|
|
|
* 1.1 and EXT_vertex_arrays is the opcode used for the DrawArrays command.
|
|
|
|
* This protocol is called "old" because the ARB is in the process of
|
|
|
|
* defining a new protocol, which will probably be called wither "new" or
|
|
|
|
* "vbo", to support multiple texture coordinate arrays, generic attributes,
|
|
|
|
* and vertex buffer objects.
