    • Provided are a 3D object graphics processing apparatus and a 3D scene graph processing apparatus. A 3D object graphics processing apparatus includes: an Appearance processing unit defining an appearance of a 3D object; a Material processing unit defining material of the appearance of the 3D object; an IndexedFaceSet processing unit defining the 3D object by using faces formed in coordinates; an IndexedLineSet processing unit defining the 3D object by using lines formed in the coordinates; a Color processing unit defining colors of the 3D object; a Coordinate processing unit defining the coordinates of the 3D object; a TextureCoordinate processing unit defining coordinate values for a texture of the appearance of the 3D object; a DirectionalLight processing unit defining a light illuminated from an infinitely distant light source in a predetermined direction in parallel; a PointLight processing unit defining a light generated from a single point source and illuminated symmetrically to all directions; a SpotLight processing unit defining a light generated from a single point source and illuminated in a particular direction within a predetermined angle range; and a Shape processing unit defining a shape of the 3D object of which the appearance has been already defined by the Appearance processing unit. Therefore, it is possible to create a 3D object by using a small number of 3D object graphics tools, so that burdens on a memory device and the size and weight of hardware can be reduced.
    • 提供了3D对象图形处理装置和3D场景图处理装置。 3D对象图形处理装置包括:外观处理单元,其界定3D对象的外观; 材料处理单元,其定义3D对象的外观材料; IndexedFaceSet处理单元通过使用坐标中形成的面来定义3D对象; IndexedLineSet处理单元,通过使用在坐标中形成的线来定义3D对象; 定义3D对象的颜色的颜色处理单元; 定义3D对象的坐标的坐标处理单元; 纹理坐标处理单元,定义3D对象的外观的纹理的坐标值; 定向光处理单元,其在预定方向上平行地限定从无限远的光源照射的光; PointLight处理单元,定义从单个点源产生的光,并对所有方向对称地照亮; SpotLight处理单元,定义从单个点源产生并在预定角度范围内沿特定方向照亮的光; 以及形状处理单元,其定义外观处理单元已经定义了外观的3D对象的形状。 因此,可以通过使用少量的3D对象图形工具来创建3D对象,从而可以减少存储器件的负担以及硬件的尺寸和重量。
