# Attenuation (OMNI,SPOT):

# Intensity of light changes with distance
|

# The attenuation factor is 1 / (c + l d + q d2)
|
||
# where d is the distance between the light and the vertex being lighted
|

# and c, l, q are the constant, linear, and quadratic coefficients.

# In Blender every object can be the parent of every other object
|
||
# In M3G that is not possible. Only a group object can be parent.

# (Or the world object which is derived from group).

# That will come later as Parenting Part 2

# Include the same image only one time into the m3g-file
|

#
|
||
# All the following changes of this version was made by Claus Hoefele
|
||
#
|
||
#* Until now all vertices of the faces was been written.
|
||
# Now the vertices will be used again if possible:
|
||
# normal and texture coordinates of to vertices have to be the same
|
||
#
|
||
#* Smooth/solid shading can now be defined for every single material:
|
||
# in Editing panel (F9)>Link and Materials
|
||
#
|
||
#* This script uses now correctly the TexFace and Shadless Buttons in
|
||
# Shading panel (F5)>Material buttons>Material box.
|
||
# TexFace switches on/off the Export of texture coordinates.
|
||
# Shadeless does the some with the normal coordinates
|
||
#
|
||
#* The GUI was redesigned in a PupBlock
|
||
#
|
||
#* Options:
|
||
#
|
||
#** Texturing Enabled: Switches on/off export of textures and texture
|
||
# coordinates. Attention: the TextFace button switches only
|
||
# for one mesh
|
||
#** Texturing External: the textures will be included it mg3-file or
|
||
# exported in seperate file
|
||
#** Lighting Enabled: turns on/off export of lights and normal completly
|
||
# Attention: Shadeless only for one mesh
|
||
#** Persp. Correction: turns on/off perspective correction in PolygonMode.
|
||
#** Smooth Shading: turns on/off smooth shading in PolygonMode.
|
||
#
|
||
#* Textures in external references are used again (with ImageFactory)
|
||
#
|
||
#* Blender function: Double Sided button in Editing Context
|
||
# (F9)>Mesh panel)
|
||
# turn on/off PolygonMode.CULL_BACK anzuschalten.
|
||
#
|
||
#* Script ingnores meshes that have no faces
|
||
#
|
||
# History 0.7
|
||
#
|
||
# * Exporter can work with texture coordinates greater 1 and smaller 0
|
||
#
|
||
# * Adler32 did not work always correct. New implementation made.
|
||
#
|
||
# * Modul shutil is not needed any longer. Exporter has its own copy_file.
|
||
# (realized and inspired by ideasman_42 and Martin Neumann)
|
||
#
|
||
# History 0.8
|
||
#
|
||
# * Blender works with SpotAngles 1..180 but M3G works only with 0..90
|
||
# M3G use the 'half angle' (cut off angle) (Thanks to Martin Storsjö)
|
||
#
|
||
# * Error fixed: Texture coordinates was not calculated correct.
|
||
# (Thanks to Milan Piskla, Vlad, Max Gilead, Regis Cosnier ...)
|
||
#
|
||
# * New options in GUI:
|
||
# M3G Version 2.0 : Will export M3G files Vers. 2.0 in future
|
||
# Game Physics: Adds Game Physics infos for NOPE API
