使用鍵盤控制上週做的茶壺手臂的動作
用鍵盤0,1,2,3 控制手臂移動
#include <stdio.h>
#include <GL/glut.h>
float angle[20]={},diff=2;
int angleID=0;//有20個angle (angle[0],angle[1]...angle[angleID])
void timer(int t){
glutTimerFunc(30,timer,t+1);
angle[angleID] += diff;
if(angle[angleID]>90)diff=-2;
if(angle[angleID]<0) diff=+2;
glutPostRedisplay();
}
void keyboard(unsigned char key,int x ,int y){
if(key=='0')angleID=0; //左ALL動
if(key=='1')angleID=1; //左下動
if(key=='2')angleID=2; //右ALL動
if(key=='3')angleID=3; //右下動
}
void display(){
glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );
glPushMatrix();
glColor3f( 1,0,1 );
glutSolidTeapot( 0.3 );//身體
glPushMatrix();
glTranslatef(-0.3,0,0);
glRotatef(angle[0], 0,0,1);
glTranslatef(-0.3,0,0);//左1
glutSolidTeapot( 0.3 );
glPushMatrix();

glPopMatrix();
glutSwapBuffers();
}
int main(int argc, char** argv){

用mouse()和motion()移動關節

oldY = y;

angle[angleID] += x - oldX;
oldX = x;
glutPostRedisplay();
}
