[Plib-devel] Vertex array code

[Vallevand, M. K <Mar...@UN...>]

Here is the vertex array code for ssg.
 <<plib.tar.gz>> 
I've included a diff file of changes to existing files, the original 
files, the changed files, and the new files.  There isn't any
documentation except this email message.  I based the changes
on plib 1.1.9.-

I've tested the main part of the code, and it works very nicely.  I
haven't tested things like the highlight or save/load code.  I have
doubts about the save/load code for any ssg object existing at
more that one point in the tree, anyway.

The new class, ssgVtxArray is similar to ssgVtxTable, but it takes
an additional parameter to its constructor: an index array. The
index array is a new type, ssgIndexArray, which stores an
array of integers to use as vertex indices.  The vertex, colour,
texture coord, and normal arrays used in the ssgVtxArray
constructor are global, shared arrays.  The index array is the
list of indices to use for the object.  There are also placeholders
for interleaved vertex array support, but that code is a future
project.

There is also too much duplicated code between ssgVtxArray and
ssgVtxTable, from which it is derived.  The code need to be work
over to get more shared code into the base class.  I would
probably need to do that when interleaved vertex support is added.
If interleaved support is never added, I'd be inclined to just leave
it alone.

I don't have cvs access, and probably don't want it.  My network
connection a home is very unreliable unless I am behind the
corporate firewall, and behind the firewall cvs doesn't work.  So,
I'm just passing the code this way.

Regards.
