动画旋转与人工控制实心茶壶旋转.doc

C语言大作业——动画旋转与人工控制是实心茶壶旋转 使用说明： 茶壶静止在窗口中 通过按上下左右键对茶壶进行旋转控制 按回车键茶壶会自动旋转 按Esc键退出程序 #include gl/glut.h #include stdio.h #include stdlib.h float red=0.7,green=0.2,blue=0.2; static GLfloat xRot = 0.0f; static GLfloat yRot = 0.0f; static float angle=0.0; void SetupLights() //设置光源 { GLfloat ambient[]={ 0.0f, 0.0f, 0.0f, 1.0f }; //环境光 GLfloat diffuse[]={1.0f,1.0f,1.0f,1.0f}; //漫反射 GLfloat position[]={0.0f, 3.0f, 2.0f, 0.0f }; //光源位置 GLfloat lmodel_ambient[]={ 1.0f, 0.0f, 1.0f, 1.0f }; //光源模型参数 GLfloat local_view[]={0.0f}; //反射方向参数 glClearColor(0.0f, 0.1f, 0.1f, 0.0f); glEnable(GL_DEPTH_TEST); glShadeModel(GL_SMOOTH); glLightfv(GL_LIGHT0,GL_AMBIENT,ambient); glLightfv(GL_LIGHT0,GL_DIFFUSE,diffuse); glLightfv(GL_LIGHT0,GL_POSITION,position); glLightModelfv(GL_LIGHT_MODEL_AMBIENT,lmodel_ambient); //使用whiteLight所指定的环境光 glLightModelfv(GL_LIGHT_MODEL_LOCAL_VIEWER,local_view); glEnable(GL_LIGHTING); glEnable(GL_LIGHT0); } void ChangeSize(int w,int h) { GLfloat fAspect; fAspect=(h==0)?1.0f:(GLfloat)w/h; glViewport(0,0,w,h); glMatrixMode(GL_PROJECTION); glLoadIdentity(); //在进行变换前把当前矩阵设置为单位矩阵 gluPerspective(45,fAspect,1,1000); //定义透视模型矩阵 glMatrixMode(GL_MODELVIEW); //指定模型视图矩阵 glLoadIdentity(); //加载单位矩阵 gluLookAt(0.0,0.0,5.0,0.0,0.0,-1.0,0.0f,1.0f,0.0f); //视图变换 } void SpecialKeys(int key, int x, int y) { if(key == GLUT_KEY_UP) xRot-= 5.0f; if(key == GLUT_KEY_DOWN) xRot += 5.0f; if(key == GLUT_KEY_LEFT) yRot -= 5.0f; if(key == GLUT_KEY_RIGHT) yRot += 5.0f; xRot = (GLfloat)((const int)xRot % 360); yRot = (GLfloat)((const int)yRot % 360); glutPostRedisplay(); } void RenderScene(void) { GLfloat no_mat[]={0.0f,0.0f,0.0f,1.0f}; GLfloat mat_ambient[]={0.7f,0.7f,0.7f,1.0f}; GLfloat mat_ambient_color[]={0.8f,0.8f,0.2f,1.0f}; GLfloat mat_diffuse[]={0.1f,0.5f,0.8f,1.0f}; GLfloat mat_specular[]={1.0f,1.0f,1.0f,1.0f}; GLfloat no_
