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.


FUNCTIONS
     SoMaterial *        SoMtlCreate()
          Creates a material node with default settings.

     SoType              SoMtlGetClassTypeId()
          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

          ambientColor   0.2 0.2 0.2
          diffuseColor   0.8 0.8 0.8
          specularColor  0 0 0

          shininess      0.2
          transparency   0
     }
