在传统的三维计算机图形（3DCG）技术中，渲染的图像是二维的。虽然3D模型用于构建3D场景，但除了从单个视点看到的信息外，渲染图像中不包含其他信息。即使在进行双目立体视觉渲染时，视点也只有两个。这一特点是传统3DCG表达的局限性。在本研究中，我们提出了一种新的3DCG艺术表达方法。我们的系统使用由平板设备和苍蝇眼睛镜头组成的集成摄影（IP）。即使设备放置在任何方向，用户也不需要佩戴特殊的眼镜就可以实现立体视觉，因为视差不仅在水平位置，而且在IP的所有方向上都是如此。一个现成的苍蝇眼睛镜头可以与各种不同屏幕分辨率的平板设备相结合，因为使用了扩展的分数视图方法。该设备体积小，重量轻，用户可以随时随地欣赏3D艺术。值得注意的是，IP可以重现这种闪闪发光的效果，因为IP显示器的每个微小凸透镜都会向不同的方向发光。我们制作了一件名为“冻结时间”的3DCG艺术品，它充分利用了我们技术的特点，以“浮冰”、“结晶化石”和“蛋白石花”为主题。
In conventional three-dimensional computer graphic (3DCG) technologies, a rendered image is two-dimensional. No information except that seen from a single viewpoint is included in the rendered image, although 3D models are used to construct a 3D scene. Even when rendering for binocular stereopsis is performed, the viewpoints are only two. This characteristic is a limitation of the conventional 3DCG expression. In this study, we propose a new approach to 3DCG art expression. Our system uses integral photography (IP) consisting of a tablet device and a fly's eye lens. Stereoscopy is possible without the need for the user to wear special glasses even if the device is placed in any orientation because parallax is caused not only in a horizontal position but also in all directions in IP. A ready-made fly's eye lens can be combined with various tablet devices that have different screen resolutions because the extended fractional view method is used. The device is so small and lightweight that users can appreciate 3D arts at any time and place. Notably, IP can reproduce such glittering effects because each minute convex lens of the IP display emits light in different directions. We produced a 3DCG artwork, called "Frozen Time," that fully employs the characteristics of our technology in motifs of "floating ice," "crystallized fossils," and an "opal flower."
