DESCRIPTION

       This node defines the current surface  material  properties  for  all  subsequent  shapes.
       SoMaterial sets several components of the current material during traversal.

       Multiple  values  can be specified for the diffuseColor and transparency. Different shapes
       interpret materials with multiple values differently. To bind materials to shapes, use  an
       SoMaterialBinding node.

FIELDS

     SoMFColor           ambientColor
          Ambient color of the surface.

     SoMFColor           diffuseColor
          Diffuse color(s) of the surface.

     SoMFColor           specularColor
          Specular color of the surface.

     SoMFColor           emissiveColor
          Emissive color of the surface.

     SoMFFloat           shininess
          Shininess  coefficient  of  the  surface. Values can range from 0.0 for no shininess (a
          diffuse surface) to 1.0 for maximum shininess (a highly polished surface).

     SoMFFloat           transparency
          Transparency value(s) of the surface. Values can range from 0.0 for opaque surfaces  to
          1.0    for   completely   transparent   surfaces.   If   the   transparency   type   is
          SoGLRenderAction::SCREEN_DOOR then only the first transparency value will be used. With
          other  transparency types, multiple transparencies will be used, if the SoMaterial node
          contains  as  many  transparencies  as  diffuse  colors.  If  there  are  not  as  many
          transparencies as diffuse colors, only the first transparency will be used.

METHODS

                         SoMaterial()
          Creates a material node with default settings.

     static SoType       getClassTypeId()
          Returns type identifier for this class.

ACTION BEHAVIOR

       SoGLRenderAction, SoCallbackAction
          Sets  the ambient color, the diffuse color, the specular color, the emissive color, the
          shininess, and the transparency of the current material.

FILE FORMAT/DEFAULTS
