先把上禮拜的程式碼開起來
第一個課堂作業
可以用鍵盤操作讓關節獨立移動!!!
程式碼:#include <stdio.h>
#include <GL/glut.h>
float angle[20]={},diff=2;
int angleID=0;
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;
if(key=='1')angleID=1;
if(key=='2')angleID=2;
if(key=='3')angleID=3;
}
void display()
{
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
glPushMatrix();
glutSolidTeapot(0.3);
glPushMatrix();
glTranslatef(-0.3,0,0);
glRotatef(angle[0],0,0,1);
glTranslatef(-0.3,0,0); glutSolidTeapot(0.3);
glutSolidTeapot(0.3);
glPushMatrix();
glTranslatef(-0.3,0,0);
glRotatef(angle[1],0,0,1);
glTranslatef(-0.3,0,0);
glutSolidTeapot(0.3);
glPopMatrix();
glPopMatrix();
glPushMatrix();
glutSolidTeapot(0.3);
glutSolidTeapot(0.3);
glPopMatrix();
glPopMatrix();
glPushMatrix();///Step05-2
glTranslatef(+0.3,0,0);
glRotatef(-angle[2], 0,0,1);
glTranslatef(+0.3,0,0);
glutSolidTeapot( 0.3 );///右手臂
glPushMatrix();///step05-3
glTranslatef(+0.3,0,0);
glRotatef(-angle[3], 0,0,1);
glTranslatef(+0.3,0,0);
glutSolidTeapot( 0.3 );///右手肘
glPopMatrix();///Step05-3
glPopMatrix();///Step05-2
glPopMatrix();///Step05-2
glutSwapBuffers();
}
int main(int argc,char** argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
glutCreateWindow("week16 many angles");
glutKeyboardFunc(keyboard);
glutDisplayFunc(display);
glutTimerFunc(0,timer,0);
glutMainLoop();
}
課堂二改用滑鼠
#include <stdio.h>
#include <GL/glut.h>
float angle[20]={};
float diff=2;
int angleID=0;
void timer (int t)
{
///timer什麼都不做
}
///用mouse和motion來控制關節
int oldX=0,oldY=0;
void mouse(int button,int state,int x,int y)
{
oldX = x;
oldY = y;
}
void motion(int x,int y)
{
angle[angleID] += x - oldX;
oldX = x;
glutPostRedisplay();
}
void keyboard(unsigned char key,int x,int y){
if(key=='0') angleID=0; ///之後timer會改變關節 angle[0]
if(key=='1') angleID=1;
if(key=='2') angleID=2;
if(key=='3') angleID=3;
}
void display()
{
glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );
glPushMatrix();
glutSolidTeapot( 0.3 ); ///身體
glPushMatrix();
glTranslatef(-0.3,0,0);
glRotatef(angle[0], 0,0,1);
glTranslatef(-0.3,0,0);
glutSolidTeapot( 0.3 ); ///左手臂, 但是,要用 T-R-T移位置
glPushMatrix();
glTranslatef(-0.3, 0,0);
glRotatef(angle[1], 0,0,1);
glTranslatef(-0.3, 0,0);
glutSolidTeapot( 0.3 ); ///左手肘
glPopMatrix();
glPopMatrix();
glPushMatrix();
glTranslatef(+0.3,0,0);
glRotatef(-angle[2], 0,0,1);
glTranslatef(+0.3,0,0);
glutSolidTeapot( 0.3 ); ///右手臂
glPushMatrix();
glTranslatef(+0.3,0,0);
glRotatef(-angle[3], 0,0,1);
glTranslatef(+0.3,0,0);
glutSolidTeapot( 0.3 ); ///右手肘
glPopMatrix();
glPopMatrix();
glPopMatrix();
glutSwapBuffers();
}
int main(int argc,char**argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE |GLUT_DEPTH);
glutCreateWindow("Week16 many angles");
glutMouseFunc(mouse);
glutMotionFunc(motion);
glutKeyboardFunc(keyboard);
glutDisplayFunc(display);
///glutTimerFunc(0,timer,0);
glutMainLoop();
}
