#NOTE:
# Copy this Script AND g3d_logo.png into .Blender\scripts
# directory then start inside blender Scripts window
# "Update Menus" after that this Script here is accesible
# as 'Wizards' G3d Fileformat Im/Exporter
#ToDo:
#Exporter Bughunt he will be rejoined next release
#Maybe Integrate UV Painter to Generate UVMaps from Blender Material and procedural Textures
#will be nice to paint wireframe too, so that one can easyly load into Paintprogram and see where to paint
#(Already possible through Blender functions so at the end of the list :-) )

"""
Here an explanation of the V4 Format found at www.glest.org
================================
1. DATA TYPES
================================
G3D files use the following data types:
uint8: 8 bit unsigned integer
uint16: 16 bit unsigned integer
uint32: 32 bit unsigned integer
float32: 32 bit floating point
================================
2. OVERALL STRUCTURE
================================
- File header
- Model header
- Mesh header
- Texture names
- Mesh data
================================
2. FILE HEADER
================================
Code:
struct FileHeader{
uint8 id[3];
uint8 version;
};
This header is shared among all the versions of G3D, it identifies this file as a G3D model and provides information of the version.
id: must be "G3D"
version: must be 4, in binary (not '4')
================================
3. MODEL HEADER
================================
Code:
struct ModelHeader{
uint16 meshCount;
uint8 type;
};
meshCount: number of meshes in this model
type: must be 0
================================
4. MESH HEADER
================================
There is a mesh header for each mesh, there must be "meshCount" headers in a file but they are not consecutive, texture names and mesh data are stored in between.
Code:
struct MeshHeader{
uint8 name[64];
uint32 frameCount;
uint32 vertexCount;
uint32 indexCount;
float32 diffuseColor[3];
float32 specularColor[3];
float32 specularPower;
float32 opacity;
uint32 properties;
uint32 textures;
};
name: name of the mesh
frameCount: number of keyframes in this mesh
vertexCount: number of vertices in each frame
indexCount: number of indices in this mesh (the number of triangles is indexCount/3)
diffuseColor: RGB diffuse color
specularColor: RGB specular color (currently unused)
specularPower: specular power (currently unused)
properties: property flags
Code:
enum MeshPropertyFlag{
mpfTwoSided= 1,
mpfCustomColor= 2,
};
mpfTwoSided: meshes in this mesh are rendered by both sides, if this flag is not present only "counter clockwise" faces are rendered
mpfCustomColor: alpha in this model is replaced by a custom color, usually the player color
textures: texture flags, only 0x1 is currently used, indicating that there is a diffuse texture in this mesh.
================================
4. TEXTURE NAMES
================================
A list of uint8[64] texture name values. One for each texture in the mesh. If there are no textures in the mesh no texture names are present. In practice since Glest only uses 1 texture for each mesh the number of texture names should be 0 or 1.
================================
5. MESH DATA
================================
After each mesh header and texture names the mesh data is placed.
vertices: frameCount * vertexCount * 3, float32 values representing the x, y, z vertex coords for all frames
normals: frameCount * vertexCount * 3, float32 values representing the x, y, z normal coords for all frames
texture coords: vertexCount * 2, float32 values representing the s, t tex coords for all frames (only present if the mesh has 1 texture at least)
indices: indexCount, uint32 values representing the indices

# Glest Model / Texture / UV / Animation Importer and Exporter
# for the Game Glest that u can find http://www.glest.org
# copyright 2005 By Andreas Becker (seltsamuel@yahoo.de)
#
# 2011/05/25: v0.1 alpha1
# modified by William Zheng for Blender 2.57(loveheaven_zhengwei@hotmail.com)
#
# Started Date: 07 June 2005 Put Public 20 June 2005
# Distributed under the GNU PUBLIC LICENSE
#"""
#Here an explanation of the V4 Format found at www.glest.org
#================================
#1. DATA TYPES
#================================
#G3D files use the following data types:
#uint8: 8 bit unsigned integer
#uint16: 16 bit unsigned integer
#uint32: 32 bit unsigned integer
#float32: 32 bit floating point
#================================
#2. OVERALL STRUCTURE
#================================
#- File header
#- Model header
#- Mesh header
#- Texture names
#- Mesh data
#================================
#2. FILE HEADER
#================================
#Code:
#struct FileHeader{
# uint8 id[3];
# uint8 version;
#};
#This header is shared among all the versions of G3D, it identifies this file as a G3D model and provides information of the version.
#id: must be "G3D"
#version: must be 4, in binary (not '4')
#================================
#3. MODEL HEADER
#================================
#Code:
#struct ModelHeader{
# uint16 meshCount;
# uint8 type;
#};
#meshCount: number of meshes in this model
#type: must be 0
#================================
#4. MESH HEADER
#================================
#There is a mesh header for each mesh, there must be "meshCount" headers in a file but they are not consecutive, texture names and mesh data are stored in between.
#Code:
#struct MeshHeader{
# uint8 name[64];
# uint32 frameCount;
# uint32 vertexCount;
# uint32 indexCount;
# float32 diffuseColor[3];
# float32 specularColor[3];
# float32 specularPower;
# float32 opacity;
# uint32 properties;
# uint32 textures;
#};
#name: name of the mesh
#frameCount: number of keyframes in this mesh
#vertexCount: number of vertices in each frame
#indexCount: number of indices in this mesh (the number of triangles is indexCount/3)
#diffuseColor: RGB diffuse color
#specularColor: RGB specular color (currently unused)
#specularPower: specular power (currently unused)
##properties: property flags
#Code:
#enum MeshPropertyFlag{
# mpfTwoSided= 1,
# mpfCustomColor= 2,
#};
#mpfTwoSided: meshes in this mesh are rendered by both sides, if this flag is not present only "counter clockwise" faces are rendered
#mpfCustomColor: alpha in this model is replaced by a custom color, usually the player color
#textures: texture flags, only 0x1 is currently used, indicating that there is a diffuse texture in this mesh.
#================================
#4. TEXTURE NAMES
#================================
#A list of uint8[64] texture name values. One for each texture in the mesh. If there are no textures in the mesh no texture names are present. In practice since Glest only uses 1 texture for each mesh the number of texture names should be 0 or 1.
#================================
#5. MESH DATA
#================================
#After each mesh header and texture names the mesh data is placed.
#vertices: frameCount * vertexCount * 3, float32 values representing the x, y, z vertex coords for all frames
#normals: frameCount * vertexCount * 3, float32 values representing the x, y, z normal coords for all frames
#texture coords: vertexCount * 2, float32 values representing the s, t tex coords for all frames (only present if the mesh has 1 texture at least)
#indices: indexCount, uint32 values representing the indices

# Glest Model / Texture / UV / Animation Importer and Exporter
# for the Game Glest that u can find http://www.glest.org
# copyright 2005 By Andreas Becker (seltsamuel@yahoo.de)

# Distributed under the GNU PUBLIC LICENSE
#"""
#Here an explanation of the V4 Format found at www.glest.org
#================================
#1. DATA TYPES
#================================
#G3D files use the following data types:
#uint8: 8 bit unsigned integer
#uint16: 16 bit unsigned integer
#uint32: 32 bit unsigned integer
#float32: 32 bit floating point
#================================
#2. OVERALL STRUCTURE
#================================
#- File header
#- Model header
#- Mesh header
#- Texture names
#- Mesh data
#================================
#2. FILE HEADER
#================================
#Code:
#struct FileHeader{
# uint8 id[3];
# uint8 version;
#};
#This header is shared among all the versions of G3D, it identifies this file as a G3D model and provides information of the version.
#id: must be "G3D"
#version: must be 4, in binary (not '4')
#================================
#3. MODEL HEADER
#================================
#Code:
#struct ModelHeader{
# uint16 meshCount;
# uint8 type;
#};
#meshCount: number of meshes in this model
#type: must be 0
#================================
#4. MESH HEADER
#================================
#There is a mesh header for each mesh, there must be "meshCount" headers in a file but they are not consecutive, texture names and mesh data are stored in between.
#Code:
#struct MeshHeader{
# uint8 name[64];
# uint32 frameCount;
# uint32 vertexCount;
# uint32 indexCount;
# float32 diffuseColor[3];
# float32 specularColor[3];
# float32 specularPower;
# float32 opacity;
# uint32 properties;
# uint32 textures;
#};
#name: name of the mesh
#frameCount: number of keyframes in this mesh
#vertexCount: number of vertices in each frame
#indexCount: number of indices in this mesh (the number of triangles is indexCount/3)
#diffuseColor: RGB diffuse color
#specularColor: RGB specular color (currently unused)
#specularPower: specular power (currently unused)
##properties: property flags
#Code:
#enum MeshPropertyFlag{
# mpfCustomColor= 1,
# mpfTwoSided= 2
#};
#mpfTwoSided: meshes in this mesh are rendered by both sides, if this flag is not present only "counter clockwise" faces are rendered
#mpfCustomColor: alpha in this model is replaced by a custom color, usually the player color
#textures: texture flags, only 0x1 is currently used, indicating that there is a diffuse texture in this mesh.
#================================
#4. TEXTURE NAMES
#================================
#A list of uint8[64] texture name values. One for each texture in the mesh. If there are no textures in the mesh no texture names are present. In practice since Glest only uses 1 texture for each mesh the number of texture names should be 0 or 1.
#================================
#5. MESH DATA
#================================
#After each mesh header and texture names the mesh data is placed.
#vertices: frameCount * vertexCount * 3, float32 values representing the x, y, z vertex coords for all frames
#normals: frameCount * vertexCount * 3, float32 values representing the x, y, z normal coords for all frames
#texture coords: vertexCount * 2, float32 values representing the s, t tex coords for all frames (only present if the mesh has 1 texture at least)
#indices: indexCount, uint32 values representing the indices

# Glest Model / Texture / Animation Exporter

# copyright 2005-2006 By Vincent Gadoury
# Started Date: December 18 2005 Put Public Decembre 20 2005
# Ver: 1.0 (Jan 30 2009)
# Distributed under the GNU PUBLIC LICENSE
# Based on g3d_support.py by Andreas Becker

###########################################################################
# (I'm sorry for the poor quality of this text,
# I'm not a native English speaker)
#
#INSTALLATION :
# Copy this Script into your .blender\scripts directory.
# if you want direct .g3d support unpack all needed glexemel files to this directory too:
# LINUX:
# In case of linux its only: xml2g and g3d.dtd ( included is a binary for linux32 bit).
# The sourcecode can be found here:
# http://www.glest.org/files/contrib/tools/glexemel-0.1a.zip
# WINDOWS:
# If you are using windows, all files from the "bin" directory from the
# following zip files are needed:
# http://www.glest.org/files/contrib/tools/glexemel_win32_0.1a.zip
#
# In Blender, open a Script Window and in the menu choose "Update Menus"
# Export with File->Export->G3D XML Exporter
#
#PREPARE THE MODEL :
# Each of your meshes' faces must be a triangle (3 vertex)
# In Edit mode, you can press Space, edit>faces>Convert to Triangles
# Create and place all your meshes before texturing or animating.
# The X axe is the floor and the Y axe is the elevation. The center
# of the Blender's 3D space will be the center of you object, at the
# ground level. Before exporting your model, apply the transformations
# to each of your mesh (In the 3D space window's menu :
# Object->Clear/Apply->Apply ... )
# This will place the center of your mesh (the yellow or pink dot)
# at the center of the Blender 3D space.
#
# !!!!!!!!!!!!!!
# !!!new since 0.1.4: !!!
# If you have a non animating model, you have to set the start frame
# and the end frame to '1' in blenders 'timeline'-window. Otherwise a non
# animating animation will be exported, containing a lot of frames and your
# model gets really big.
# !!!!!!!!!!!!!!
#
# Before doing any texturing or animation, try to export your model and
# check your python console (the terminal which opens Blender) to see
# if there is a warning about the number of used faces in the summary.
# If there is, try to delete "false" faces (which use only 2 vertices)
# and transform all your faces in triangle.
#
#EXPORTING :
# You MUST select the meshes you want to export.
# Only meshes are exported among the selected objects.
#
# The diffuse color of the mesh will be it's (first) material's color.
# The opacity of the mesh will be it's material's alpha.
# Double sided property of the mesh is exported (see F9).
# If you want to use custom color in the texture, your mesh must be
# double sided. If you don't want custom color to be activated for the
# mesh, add a new boolean property to it (F4) named customColor and with
# the false value. Custom Color set if the alpha of the texture is
# replaced for the color of the player.
#
#TEXTURING :
# To use a texture for the mesh, you must add a texture at the FIRST
# position to the mesh's material. The texture type must be 'image'
# and you should insert the real image. In fact, only the filename
# of the image is used. After having mapped the image on the
# mesh with UV Face selection, you don't need anymore to "stick"
# the coordinates to the vertices.
# Your texture's format must be TGA, without compression and with the origin
# at the bottom left position. The side of the image must be a multiple
# of 2. In practice, you must use only one image for all your meshes.
#
#ANIMATING :
# You can export all animations made with blenders armature system.
# You have to set the start frame and the end frame in the 'timeline'-window
# to define the animation which will be exported.
# If you animate without using the armatures it will not work!!
#
# LINKS :
# Animating with armatures
# http://www.blender.org/documentation/htmlI/x1829.html
# Map an image on your mesh with UV Face selection :
# http://en.wikibooks.org/wiki/Blender_3D:_Noob_to_Pro/UV_Map_Basics
# http://download.blender.org/documentation/htmlI/ch11s05.html
#
#CONVERT TO .G3D
# The following is no longer needed if you copied g3d.dtd and xml2g(.exe) next
# to this script:
#
# Use the xml2g program of the glexemel tool at
# http://www.glest.org/files/contrib/tools/
# Syntax : ./xml2g ExportedFile.xml DesiredFile.g3d
#
# WARNING : The current version of this program don't seems to work...
# You'll have to add the lines (if they aren't there) :
# #pragma pack(push, 1)
# near of the beginning of the file "g3dv4.h" of glexemel and
# #pragma pack(pop)
# before the #endif
#
#
#ChangeLog :
# 1.1: by Titus Tscharntke (titi)
# fixed bug in windows ( problems with file sparator char )
# 1.0: Big thanks go to Frank Tetzel (Yggdrasil) who finally made a
# direct export to .g3d possible. If you copy g3d.dtd and
# xml2g(.exe) next to this script it will export to .g3d.
# If not, it will export to .xml like before.
#
# 0.1.7 : by Titus Tscharntke (titi)
# removed non 7-bit ascii characters for newer versions of python
# 0.1.6 : by justWeedy(weedkiller)
# Basic colorsettings for maps are often unused but may cause
# models look "bright".
# There are Hardcoded defauld values to avoid this.
# Turn On/Off due the boolean <useHardCodedColor>
# 0.1.5 : by weedkiller
# You don't have to apply scale and rotation anymore
# 0.1.4 : by weedkiller and Titus Tscharntke ( www.titusgames.de )
# New implementation of the animation export ( including some usage changes!!! )
# Exporting animations is now possible with newer Blender versions ( tested with 2.43 )
#
# 0.1.3 : by Titus Tscharntke ( www.titusgames.de )
# Fixed a bug with getProperty() in blender 2.43
#
# 0.1.2 :
# Correcting an execution bug
# Adding the "frameCount" property for each object
# Using only the triangle faces for the index count
# (problems of linking between index and vertex may occur)
# Adding the summary display in the python console
# Adding a better documentation
# 0.1.1b :
# Adding a vertex duplication method to correct the vertex UV problem.
# Correcting NMVert.uvco misuse
#
#ToDo:
# More tests...
# More validations...
# Warn the user if there is something wrong, e.g. :
# - no mesh among the selected objects;
# - texture without uvco;
# - no material on a mesh.
# Test and correct the theoric linking problem if faces are ignored...
