实验五造型的动画效果(需交实验报告).doc

实验五 造型的动画效果（需交实验报告）一、 实验内容1. 理解VRML中动画实现的基本原理2. 利用TimeSensor时间传感器节点和各种插补节点完成各种动画效果的制作二、 实验环境1. 硬件环境计算机一台2. 软件环境VrmlPad编辑器和CortonaPlayer浏览器三、 实验步骤1. 设计实现一个垂直于Z轴并绕Z轴旋转的十字架的造型，并且旋转地过程中十字架的两根金属棒分别进行不同的颜色变换。首先利用transform节点构造两根金属棒的造型，然后设计一个TimeSensor时间传感器驱动整个动画的运行，设计两个OrientationInterpolator朝向插补节点分别控制造型的旋转，设计两个ColorInterpolator颜色插补节点分别控制造型的颜色变换。代码：#VRML V2.0 utf8DEF ColorInterpolator1 ColorInterpolator key 4.400977e-2 0.194376 0.271393 0.295843 0.360635 0.372860 0.429095 0.446210 0.528117 0.595354 0.669926 0.880195 0.922982 keyValue 0 0 0 0 0 0.846153 0 0 1 0 1 5.769230e-2 0 0 0.401075 7.017529e-2 1 0.288461 1 0.423076 0.730769 1 7.692307e-2 0.913995 1 0 0.557692 0.615384 0 0 0 0 0 0 0 0 0 0 0 DEF ScalarInterpolator1 ScalarInterpolator key 6.112469e-3 0.288508 0.399755 0.504889 0.573349 0.644254 0.679706 0.699266 0.740831 0.793398 0.823960 0.880195 keyValue 1.999241e-2 1.923076e-2 0.827769 0.403846 0.807692 0.538461 3.846153e-2 7.692307e-2 0.305588 0.757417 0.769230 0.192307 Group children DEF b Transformchildren Transform translation 2 0 0 children DEF A Shape appearance Appearance material DEF Material1 Material ambientIntensity 1 diffuseColor 0.566954 0.474150 0.744087 emissiveColor 0.478201 5.769230e-2 3.846153e-2 shininess 1 transparency 0.192307 geometry Cylinder height2 radius 0.2 Transform translation 2 0 0 rotation 0 0 1 1.571 children USE A DEF Clock TimeSensor cycleInterval 6.0 loop TRUE , DEF BallPath OrientationInterpolator key 0,0.5 1.0 keyValue 0 0 1 0, 0 0 1 3.14, 0 0 1 6.28, ROUTE Clock.fraction_changed TO BallPath.set_fractionROUTE BallPath.value_changed TO b.set_rotationROUTE ColorInterpolator1.value_changed TO Material1.set_specularColorROUTE ScalarInterpolator1.value_changed TO Material1.set_transparencyDEF ColorInterpolator2 ColorInterpolator key 9.657701e-2 0.179706 0.228606 0.306845 0.444987 0.475550 0.520782 0.550122 0.622249 0.638141 0.710268 0.729828 0.859413 0.903423 0.946210 keyValue 0.115384 1.923076e-2 0.288461 0 5.769230e-2 0.211538 0 0 0.230769 0.335227 0.153846 0 1 0.365384 0.923076 0.952988 0.846153 0.711538 0.271321 0.443570 0 0.192307 0.383234 0.711538 0.718668 0.246277 0 1 0.750000 0.711538 0.576923 0.173076 0.211538 0.230769 0.961538 0.660256 1 0.173076 0.980769 1 0.942307 0.346153 0.288461 0.173076 1 ROUTE ColorInterpolator2.value_changed TO Material1.set_diffuseColorDEF ColorInterpolator3 ColorInterpolator key 0.123471 0.261613 0.283618 0.315403 0.525672 0.636919 0.646699 0.678484 0.871638 0.993887 keyValue 0 0 0 0 0 0 0 0 1 0 0 0 0 0 7.692307e-2 0 3.846153e-2 1.398602e-2 0 1 0 1.619984e-2 3.846153e-2 6.479939e-3 9.615384e-2 5.769230e-2 3.846153e-2 0.903846 5.769230e-2 3.846153e-2 ROUTE ColorInterpolator3.value_changed TO Material1.set_emissiveColorTransform children Shape appearance Appearance material Material translation -5.912889 1.079226 0 DEF TimeSensor1 TimeSensor cycleInterval 10 loop TRUE ROUTE TimeSensor1.fraction_changed TO ScalarInterpolator1.set_fractionROUTE TimeSensor1.fraction_changed TO ColorInterp
