手和腳都出來了(大手.小手)

程式碼:

#include <GL/glut.h>

#include <opencv/highgui.h>

#include <opencv/cv.h>

#include <stdio.h>

//IplImage *img1, *img2, *img3, *img4;

float angleX=0;

void myPrepareTexture(int i)//用參數來配, 找對應正確的變數

}

void myTexture()

{

img[0]=cvLoadImage("body.png");

img[1]=cvLoadImage("Hand1.png");

img[2]=cvLoadImage("Leg1.png");

for(int i=0;i<3;i++){//技巧2: 可以把重覆的東西, 用迴圈來簡化

myPrepareTexture(i);

}

void myPolygon(int num){//技巧3: 可以把重覆的東西, 用函式來簡化

glPushMatrix();

glScalef(0.3, 0.8, 0.8);

glBindTexture(GL_TEXTURE_2D, id[num]);

glBegin(GL_POLYGON);

glEnd();

glPopMatrix();

}

void myBody(){

myPolygon(0);

}

void myLeg(){

glPushMatrix();

glScalef(0.5,0.5,0.5);

myPolygon(1);

glPopMatrix();

}

void myHand(){

glPushMatrix();

glScalef(0.5,0.5,0.5);

myPolygon(2);

glPopMatrix();

}

void display()

{

glEnable(GL_DEPTH_TEST);

glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

glPushMatrix();

glScalef(0.5,0.5,0.5);

myBody();

glPushMatrix();

glTranslatef(0.2,0,0);//右手

glRotatef(angleX, 0,0,1);

glTranslatef(0, -0.2, 0);

myHand();

glPushMatrix();

glTranslatef(0,-0.2,0);//小右手

glRotatef(-angleX, 0,0,1);

glTranslatef(0, -0.2, 0);

myHand();

glPopMatrix();

glPushMatrix();

glTranslatef(-0.2,0,0);//左手

glRotatef(-angleX, 0,0,1);

glTranslatef(0, -0.2, 0);

glPushMatrix();

glTranslatef(0,-0.2,0);//小右手

glPushMatrix();

glTranslatef(-0.2,-0.3,0);//左腿

glRotatef(-angleX, 0,0,1);

glTranslatef(0, -0.2, 0);

glPopMatrix();

glPushMatrix();

glTranslatef(0.2,-0.3,0);//右腿

glRotatef(-angleX, 0,0,1);

glTranslatef(0, -0.2, 0);

myLeg();

glPopMatrix();

glutSwapBuffers();

}

void keyboard(unsigned char key, int x, int y)

{

if(key=='a') angleX+=3;

if(key=='b') angleX-=3;

glutPostRedisplay();

}

int main()

{

glutInitDisplayMode(GLUT_DOUBLE |GLUT_DEPTH);

glutCreateWindow("week12");

glutDisplayFunc(display);

glutKeyboardFunc(keyboard);

myTexture();//不要忘了加哦!

glutMainLoop();

}

利用數字1~8分別控制關節點

加入程式碼:

float angle1=0, angle2=0, angle3=0, angle4=0, angle5=0, angle6=0, angle7=0, angle8=0;

void keyboard(unsigned char key, int x, int y)

{

if(key=='1') angle1+=3;

if(key=='2') angle1-=3;

if(key=='3') angle2+=3;

if(key=='4') angle2-=3;

if(key=='5') angle3+=3;

if(key=='6') angle3-=3;

if(key=='7') angle4+=3;

if(key=='8') angle4-=3;

glutPostRedisplay();

}
