NAME

     OSUInventorScene - C++ class  for  reading  an  OpenInventor
     scene

SYNOPSIS

     A C++ class for reading an OpenInventor scene from a file.

OSUInventorScene CONSTRUCTOR

     OSUInventorScene(char * filename)
          Open file filename and read the OpenInventor scene from
          the  file.   Store  objects  in the Objects list, store
          lights in the Lights list and store the camera (if  one
          exists) in Camera.

OSUInventorScene DATA

     SbPList Objects
          A list of objects of type OSUObjectData.

     SbPList Lights
          A list of OpenInventor lights.

     SoCamera *Camera
          Pointer to a camera.  May be NULL (0) if no camera  was
          found in the input file.

OSUObjectData DATA

     SoNode *shape
          Shape stored at the node, i.e., sphere, cube, quadmesh,
          triangle strip.

     SoTransform *tranformation
          Transformation which maps shape from  object  to  world
          coordinates.   OSUInventorScene  puts  together all the
          transformations applied to a shape  to  give  a  single
          transformation for that shape.  Transformation consists
          of a scaling, followed by  a  rotation  followed  by  a
          translation.

     SoMaterial *material
          Material properties.  Contains  the  ambient,  diffuse,
          specular  and emissive color, the shininess coefficient
          and the transparency.

     SoNode *points
          List of point coordinates for use in  triangle  strips,
          quad meshes, etc.

     SoNormal *normal
          List of normal vectors.

     SoNode *texture_points
          List of points for defining texture.

     SoNode *texture
          Texture.  Contains the file name of the SGI  .rgb  file
          containing the texture.

     TextureType texture_type
          Flag for defining procedural textures.  This is not  an
          OpenInventor object.

     SoDrawStyle draw_style
          Drawing style. Filled, lines  (wireframe,)  points,  or
          invisible.

     SoComplexity complexity
          Hint for how to render an object based on its geometric
          complexity.
