计算机图形学实验报告实验四：Robot 学号： 姓名： 成绩： 东南大学计算机科学与工程系一、 实验目的利用层级建模方法设计并实现一个物体，至少由三部分组成，并可交互控制其相对运动。二、 实验代码说明那个：代码原理重复部分太多，所以贴了函数里面的一部分做代表。void init(void) glClearColor (0.0, 0.0, 0.0, 0.0); glShadeModel (GL_FLAT); glColor3f(0.0f,1.0f,1.0f); glMatrixMode(GL_PROJECTION); glPushMatrix(); glLoadIdentity(); gluOrtho2D(0, w, 0, h); glScalef(1, -1, 1); glTranslatef(0, -h, 0); glMatrixMode(GL_MODELVIEW); glPushMatrix(); glLoadIdentity(); renderBitmapString(30,15,(void *)font,robot); renderBitmapString(30,35,(void *)font,Introduction );renderBitmapString(30,55,(void *)font,w -go head); renderBitmapString(30,75,(void *)font,s -turn back); renderBitmapString(30,95,(void *)font,a -turn left); renderBitmapString(30,115,(void *)font,d -turn right); renderBitmapString(30,135,(void *)font,1,2 control left big arm and left little arm );renderBitmapString(30,155,(void *)font,3,4 control right big arm and right little arm ); renderBitmapString(30,175,(void *)font,5,6 control left big leg and left little leg ); renderBitmapString(30,195,(void *)font,7,8 control right big leg and right little leg ); renderBitmapString(30,215,(void *)font,Esc - Quit); glPopMatrix(); glMatrixMode(GL_PROJECTION); glPopMatrix(); glMatrixMode(GL_MODELVIEW); void display(void) glClear (GL_COLOR_BUFFER_BIT); glPushMatrix(); glTranslatef (forward,0.0,z); glRotatef (GLfloat) turn, 0.0, 1.0, 0.0); glTranslatef (-0.375, -0.5, 0.0);/左大腿 glRotatef (GLfloat) joint5, 1.0, 0.0, 0.0); glColor3f(0.0,1.0,0.0); glPushMatrix(); glScalef (0.5, 1.0, 0.5); glutWireCube (1.0); glPopMatrix(); glTranslatef (0.0, -1.0, 0.0);/左小腿 glRotatef (GLfloat) joint6, 1.0, 0.0, 0.0); glColor3f(0.0,0.0,1.0); glPushMatrix(); glScalef (0.5, 1.0, 0.5); glutWireCube (1.0); glPopMatrix(); glTranslatef (0.0, -0.5, -0.1);/左脚 glColor3f(0.0,0.0,1.0); glPushMatrix(); glScalef (0.5, 0.1, 0.7); glutWireCube (1.0); glPopMatrix(); glPopMatrix(); glPushMatrix(); glTranslatef (forward,0.0,z); glRotatef (GLfloat) turn, 0.0, 1.0, 0.0); glTranslatef (0.0, 1.0, 0.0);/躯干 glColor3f(0.0,0.0,1.0); glPushMatrix(); glScalef (1.4, 2.0, 0.5); glutWireCube (1.0); glPopMatrix(); glTranslatef (0.0, 1.25, 0.0);/头 glColor3f(1.0,0.0,0.0); glPushMatrix(); glScalef (0.5, 0.5, 0.5); glutWireCube (1.0); glPopMatrix(); glPopMatrix(); glPushMatrix(); glTranslatef (forward,0.0,z); glRotatef (GLfloat) turn, 0.0, 1.0, 0.0); glPopMatrix(); init();glutSwapBuffers(); void renderBitmapString(float x, float y, void *font,char *string) char *c; glRasterPos2f(x, y); /设置光栅位置 for (c=string; *c != 0; c+) glutBitmapCharacter(font, *c); /显示字符 void keyboard (unsigned char key, int x, int y) switch (key) case 1:joint1+= 5.0;if(joint1 360)joint1-=360; break; case w: /向后 turn1=turn; forward = forward -0.04*sin(GLfloat)turn1/360*3.14*2); z=z-0.05*cos(GLfloat)turn1/360*3.14*
