#ifndef _LOVE_H_

/*
What do we need as an internal world object format?
Can't call it Things, that's taken already.
"Stuffs" works though. B-)
Love server needs to manage in world stuffs, and send changes to everyone.
Extantz needs to manage what's shown in world, and edit that stuffs.
Combining the data structures seems sane. Letting the love server
define those data structures also seems sane, hence this file.
Extantz needs -
what it looks like (Evas_3D stuff)
"link sets"
what is attached to what
mesh
vertices, triangles, ...
local position and orientation relative to parent
material
textures
colours, including alpha
light
shade mode
where it is
position, orientation
animation stuff
common
UUID
name & description
owner
position, orientation
"link sets"
love needs
UUID
name & description
owner
position, orientation
"link sets"
LL used a list of prims, we can do better I'm sure.
Though for the sake of this experimental version, just use an array of stuffs.
contents
scripts, cards, other stuffs, animations, sounds, textures, ...
content types
*/
/* Stuffs is a single "primitive" object, it can be -
single mesh object - NOTE: Should include a list of materials.
LL style prim, including tree, defined as a small bunch of data defining the type and parameters
LL style mesh "file"
single mesh file, collada, other mesh format
height field, for land, or water
LuaSL script
"notecard", just a text file, with no limits
animation, BVH, Alice's BVJ, or perhaps any other animation file format
sounds, MP3, other sound formats
textures, PNG, JPEG, JPEG2000, TIFF, GIF, other texture formats
other LL stuff
landmark
clothing
body part, shape, skin, hair, or eyes
gesture
calling card
