【摘要】 该论文主要从背景，人物角色，三维合成等几个方面去完成。动画背景与普通绘画有相似的方面，但也有不同。在水彩绘画中，一般会有画面主体，会用虚实结合及笔触等因素的运用来突出主体部分，弱化背景和陪衬部分。但在动画背景的绘制中，不需要这种主次关系和虚实关系在，这些工作都是在计算机中的摄影机镜头中来实现。这部水彩动画中的角色采用纯电脑，三维模拟二维的制作方式。由于这里主要是研究水彩效果的实现，所以模型的制作和骨骼的设定以及UV的划分等内容在这里不做解释，但是这些部分要细致调整才可以为后面的效果提供必要的保证。既然要把水彩画应用到动画中，那么合成无疑成为最关键的一个组成部分。片子能否自然过度，前景与背景能否实现良好的层次关系都取决于合成的掌握。三维合成其实并不能算是一种必要的流程，只能算一种技巧，这种合成通常用在角色要在手绘的背景中进行活动，也就是说动画背景已经不仅仅简单的充当背景了，还要充当场景。角色有可能在这张背景中的石头坐下，还有可能爬上背景中某棵树上等等。相当于把一张图片作为一个三维的场景来使用。在这种情况下，最有可能出现的就是透视问题。人物的透视是否能符合场景中的透视直接关系到这个人物是否真正的立足于场景中，因此在这一部分要解决的重点问题是三维合成部分。在该片中我采用了如下的方法来实现三维与二维合成的精准定位与透视。输出是至关重要的一步，如何选择好的音乐以及如何给片子加一个好的片头都是这部分的重点。水彩的一个重要特征就是水痕，在制作之前，可以在水彩纸上做多次的测试，可以只要黑白效果，颜色部分在photoshop里调节将会有更大的空间和灵活度。把满意的水痕效果采集到电脑中，在photoshop里利用叠加的方式合成一个颜色贴图即可出现一副水彩效果的背景画面。更多还原

【Abstract】 My thesis include in background character and composition etc. There are somesimilar point in paint and animation. The difference is main part. In watercolorpainting, the general picture will be main body, will use always mix and the use ofsuch factors as the brush to highlight the main body part and weaken the backgroundand foil parts. But in the animation of the background of the draw, don’t need thiskind of primary and secondary relations and the actual situation relations in, all thiswork was in the computer in the lens camera to realize.The watercolor animation through pure the role in the computer, threedimensional simulation 2 d production mode. It is mainly study the realization ofwatercolor effect, so the production and skeletal model set and the division of UV etcin here don’t do explain, but these part to adjust the can for the detailed the effect toprovide necessary guarantee.Since the application to watercolor animation, the synthesis has become the keyto that of a component. The film can be natural excessive, foreground and backgroundcan achieve good level depends on the relationship of synthesis of master. 3 dsynthesis actually is not a necessary process is only a skill, the synthesis is often usedin part to hand in the background of the activities, that is the background is not onlysimple animation as a background, and ACTS as a scene. Role may on this piece ofstone of the background to sit down, and may climb a tree in the background, and soon. The equivalent of a picture as a three dimensional scene to use. In this case, of themost likely is the problem. The characters are to meet the scene in the perspective ofthe character directly related to whether the real based on the scene, so in this part ofthe problem is the key to solve the three dimensional synthesis parts. And in this filmI use the following method to realize 3 d and 2 d synthesis of accurate positioning andperspective.Output is crucial step, how to choose a good music and how to give the film witha good titles out is this part of the key. One of the most important features ofwatercolor is water mark, before in the production, can be in the water on the paper tomake a number of test, can be as long as black and white effect, color component inphotoshop adjust the will have larger space and flexibility. The satisfaction of thewater mark effect collection to the computer, using the stack in photoshop waysynthesis a color map can appear a pair of watercolor effect backgrounds.更多还原
