(1)虚拟现实技术在舞美中的应用。<br> 计算机神奇的表现力使理想形态的创造达到随心所欲的境地。计算机三维技术有极强的仿真能力和创造力，它可以在虚拟的空间里，创造出极其逼真的世界，又可以凭借想像力创造出大自然的视野，在三维动画所表现的空间画面中，以超现实的表现力设计出动态的理想世界，在这里传统的描绘材料工具及技法都望尘莫及。传统的舞美设计，总是先要有一个初步构思，画出草图，通过与导演和各部门的协商，让构思具体化，然后画出效果图。但是手画的效果图是二维空间表现三维空间的，与真实的场景有一定的差距，又很不直观。另外灯光的效果也无法体现， 因为一台晚会的灯光变化是很多的，不可能每一种变化都要画一张效果图。所以，舞美设计的最终面貌还是要到装台后才能看到。在舞台上，灯光布景都装好后，一旦对光时发现灯光、布景存在什么问题或有什么不足之外的话， 想改是很困难的。利用计算机三维技术可以在一定程度上解决这些问题。<br> 特别对于灯光设计效果图来说，应该充分表现出光与景的关系，表现出不同材质、不同介质的特点，准确地表现光线、包括光线在空间的造型。而利用计算机灯光设计软件，可在瞬时对颜色、材质、影子、光及大量附加效果进行如意的编辑、强大的动画工具和快速的图像生成功能，可以使灯光效果图更接近现场的效果，达到艺术设计理念的氛围。当电脑作为对舞台演出灯光的控制设备时，即可严格依照灯光设计者键入的编程方案，迅速而准确无误地调控灯具完成对光色的组合、移动、变化，极大地强化了舞台灯光的可控性和可塑性，从而拓展了设计者对假定时空的想象和创造及舞台体现前瞻能力。

(1) The application of virtual reality technology in dance beauty.<br>The magical expressive power of computer makes the creation of ideal form reach the situation of doing whatever you want. Computer three-dimensional technology has strong simulation ability and creativity. It can create an extremely realistic world in the virtual space, and can create the vision of nature by virtue of imagination. In the space picture represented by three-dimensional animation, it can design a dynamic ideal world with surreal expressiveness. Here, the traditional description materials, tools and techniques can't catch up with it. Traditional dance design always needs to have a preliminary idea, draw a sketch, make the idea concrete through consultation with the director and various departments, and then draw an effect drawing. However, hand drawn renderings represent three-dimensional space in two-dimensional space, which is not intuitive and has a certain gap with the real scene. In addition, the effect of light can not be reflected, because there are many changes in the light of a party, it is impossible to draw an effect picture for each change. Therefore, the final appearance of dance beauty design can only be seen after installation. On the stage, after the lighting and scenery are installed, it is very difficult to change once you find any problems or deficiencies in the lighting and scenery. These problems can be solved to some extent by using computer three-dimensional technology.<br>Especially for lighting design renderings, they should fully show the relationship between light and scenery, the characteristics of different materials and media, and accurately show the light, including the modeling of light in space. By using the computer lighting design software, you can instantly edit the color, material, shadow, light and a large number of additional effects, powerful animation tools and fast image generation function, which can make the lighting effect map closer to the effect of the scene and achieve the atmosphere of art design concept. When the computer is used as the control equipment for stage performance lighting, it can quickly and accurately control the lamps and lanterns to complete the combination, movement and change of light and color in strict accordance with the programming scheme typed by the lighting designer, which greatly strengthens the controllability and plasticity of stage lighting, and expands the designer's imagination and creation of hypothetical time and space and the foresight ability of stage embodiment.

(1) The application of virtual reality technology in dance beauty. The magical expressive force of computer makes the creation of ideal form reach the arbitrary position. Three-dimensional computer technology has strong simulation ability and creativity. It can create an extremely realistic world in the virtual space, and also create the natural vision with imagination. In the space picture represented by three-dimensional animation, the dynamic ideal world is designed with surreal expressive force, where the traditional tools and techniques of depicting materials are far behind. Traditional dance beauty design always requires a preliminary idea, drawing a sketch, concretizing the idea through consultation with directors and various departments, and then drawing the effect map. However, hand-drawn renderings represent three-dimensional space in two-dimensional space, which has a certain gap with the real scene and is not intuitive. In addition, the effect of lighting can not be reflected, because there are many changes in the lighting of a party, and it is impossible to draw an effect map for every change. Therefore, the final appearance of the dance beauty design can't be seen until the stage is installed. On the stage, once the lights and scenery are installed, it is very difficult to change them if there are any problems or deficiencies in the lights and scenery. Using computer 3D technology can solve these problems to some extent. Especially for lighting design renderings, we should fully show the relationship between light and scenery, show the characteristics of different materials and different media, and accurately show light, including the shape of light in space. By using the computer lighting design software, the color, material, shadow, light and a large number of additional effects can be edited instantly, powerful animation tools and fast image generation function can make the lighting effect drawing closer to the scene effect and achieve the atmosphere of artistic design concept. When the computer is used as a control device for stage performance lighting, it can quickly and accurately adjust and control the lamps and lanterns to complete the combination, movement and change of light and color in strict accordance with the programming scheme typed by the lighting designer, which greatly strengthens the controllability and plasticity of stage lighting, thus expanding the imagination and creation of the designer on assumed time and space and the forward-looking ability of stage expression.
