# Blender.Material module and the Material PyObject

"""
The Blender.Material submodule.

B{New}: L{Material.clearScriptLinks} accepts a parameter now.

Material 
========

This module provides access to B{Material} objects in Blender.

Example::
  import Blender
  from Blender import Material
  mat = Material.New('newMat')          # create a new Material called 'newMat'
  print mat.rgbCol                      # print its rgb color triplet sequence
  mat.rgbCol = [0.8, 0.2, 0.2]          # change its color
  mat.setAlpha(0.2)                     # mat.alpha = 0.2 -- almost transparent
  mat.emit = 0.7                        # equivalent to mat.setEmit(0.8)
  mat.mode |= Material.Modes.ZTRANSP    # turn on Z-Buffer transparency
  mat.setName('RedBansheeSkin')         # change its name
  mat.setAdd(0.8)                       # make it glow
  mat.setMode('Halo')                   # turn 'Halo' "on" and all others "off"

@type Modes: readonly dictionary
@var Modes: The available Material Modes.
    - TRACEABLE    - Make Material visible for shadow lamps.
    - SHADOW       - Enable Material for shadows.
    - SHADELESS    - Make Material insensitive to light or shadow.
    - WIRE         - Render only the edges of faces.
    - VCOL_LIGHT   - Add vertex colors as extra light.
    - VCOL_PAINT   - Replace basic colors with vertex colors.
    - HALO         - Render as a halo.
    - ZTRANSP      - Z-buffer transparent faces.
    - ZINVERT      - Render with inverted Z-buffer.
    - - HALORINGS  - Render rings over the basic halo.
    - ENV          - Do not render Material.
    - - HALOLINES  - Render star shaped lines over the basic halo.
    - ONLYSHADOW   - Let alpha be determined on the degree of shadow.
    - - HALOXALPHA - Use extreme alpha.
    - TEXFACE      - UV-Editor assigned texture gives color and texture info
        for faces.
    - - HALOSTAR   - Render halo as a star.
    - NOMIST       - Set the Material insensitive to mist.
    - - HALOSHADED - Let halo receive light.
    - HALOTEX      - Give halo a texture.
    - HALOPUNO     - Use the vertex normal to specify the dimension of the halo.
    - HALOFLARE    - Render halo as a lens flare.
    - RAYMIRROR    - Enables raytracing for mirror reflection rendering.
    - RAYTRANSP    - Enables raytracing for transparency rendering.
@warn: Some Modes are only available when the 'Halo' mode is I{off} and
    others only when it is I{on}.  But these two subsets of modes share the same
    numerical values in their Blender C #defines. So, for example, if 'Halo' is
    on, then 'NoMist' is actually interpreted as 'HaloShaded'.  We marked all
    such possibilities in the Modes dict below: each halo-related mode that
    uses an already taken value is preceded by "-" and appear below the normal
    mode which also uses that value.
