# "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

||||

|

#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
