馬馬joe的奇幻冒險

電腦圖學 2019-05-02 Week11

1.小考:T-R-T 轉動

2. 主題:階層轉動骨架

3.主題:鍵盤按鍵

4.#include <GL/glut.h>
float angle=0;
void display()
{
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    glColor3f(255,255,255);
    glPushMatrix();
        glRotatef(angle,0,0,1);
        glColor3f(255,0,0);
        glutSolidTeapot(0.2);
    glPopMatrix();
    glutSwapBuffers();
    angle++;
}
int main(int argc, char**argv)
{
   glutInit(&argc, argv);
   glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
    glutCreateWindow("06160396-week11");
    glutDisplayFunc(display);
    glutIdleFunc(display);
    glutMainLoop();
}
在codeblocks打開會出現下圖

5.在CodeBlocks打上
#include <GL/glut.h>
float angle=0;
void display()
{
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    glColor3f(255,255,255);
    glutSolidTeapot(0.3);
    glPushMatrix();
        glTranslatef(0.2,0,0);
        glRotatef(angle,0,0,1);
        glTranslatef(0.28,0,0);

    glColor3f(255,0,0);
    glutSolidTeapot(0.2);

    glPushMatrix();
        glTranslatef(0.2,0,0);
        glRotatef(angle,0,0,1);
        glTranslatef(0.28,0,0);

        glColor3f(255,0,0);
        glutSolidTeapot(0.2);
        glPopMatrix();
    glPopMatrix();

        glPushMatrix();
        glTranslatef(-0.2,0,0);
        glRotatef(angle,0,0,1);
        glTranslatef(-0.28,0,0);

    glColor3f(255,0,0);
    glutSolidTeapot(0.2);

    glPushMatrix();
        glTranslatef(-0.2,0,0);
        glRotatef(angle,0,0,1);
        glTranslatef(-0.28,0,0);

        glColor3f(255,0,0);
        glutSolidTeapot(0.2);
        glPopMatrix();
    glPopMatrix();
    glutSwapBuffers();
    angle++;
}
int main(int argc, char**argv)
{
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
    glutCreateWindow("06160396-week11");
    glutDisplayFunc(display);
    glutIdleFunc(display);
    glutMainLoop();
}
會出現以下如圖

6.用鍵盤來控制手臂
#include <GL/glut.h>
float angle1,angle2,angle3,angle4;
int joinID=1;
void display()
{
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glColor3f(255,255,255);///白色
    glutSolidTeapot( 0.3 );///身體
    ///右邊的手臂
    glPushMatrix();
    glTranslatef(0.2, 0,0 );///(3)往右移動, 掛在身體的右肩
    glRotatef(angle1, 0,0,1);///(2)旋轉
    glTranslatef(0.28, 0,0);///(1)往右推,把茶壼的柄,放到中心,變 轉動軸

    glColor3f(255,0,0);///紅色
    glutSolidTeapot( 0.2 );///手臂

    glPushMatrix();
    glTranslatef(0.2, 0,0 );
    glRotatef(angle2, 0,0,1);
    glTranslatef(0.28, 0,0);

    glColor3f(255,0,0);///紅色
    glutSolidTeapot( 0.2 );///手臂
    glPopMatrix();
    glPopMatrix();



   glPushMatrix();
    glTranslatef(-0.2, 0,0 );///(3)往右移動, 掛在身體的右肩
    glRotatef(angle3, 0,0,1);///(2)旋轉
    glTranslatef(-0.28, 0,0);///(1)往右推,把茶壼的柄,放到中心,變 轉動軸

    glColor3f(255,0,0);///紅色
    glutSolidTeapot( 0.2 );///手臂

    glPushMatrix();
    glTranslatef(-0.2, 0,0 );
    glRotatef(angle4, 0,0,1);
    glTranslatef(-0.28, 0,0);

    glColor3f(255,0,0);///紅色
    glutSolidTeapot( 0.2 );///手臂
    glPopMatrix();
    glPopMatrix();

    glutSwapBuffers();
    ///angle++;
}
    void motion(int x,int y)
    {
        if(joinID==1) angle1=x;
        if(joinID==2) angle2=x;
        if(joinID==3) angle3=x;
        if(joinID==4) angle4=x;
        display();
    }
    void keyboard(unsigned char key,int x,int y)
    {
        if(key=='1') joinID=1;
        if(key=='2') joinID=2;
        if(key=='3') joinID=3;
        if(key=='4') joinID=4;
        display();
    }
int main(int argc, char**argv)
{
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
    glutCreateWindow("week11 06160396");
    glutIdleFunc(display);///Now!!!!
    glutDisplayFunc(display);
    glutMotionFunc(motion);
    glutKeyboardFunc(keyboard);
    glutMainLoop();
}

會出現以下圖片

7.把地6個程式碼變成更乾淨
#include <GL/glut.h>
float angle[20];
int joinID=1;
void display()
{
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glColor3f(255,255,255);///白色
    glutSolidTeapot( 0.3 );///身體
    ///右邊的手臂
    glPushMatrix();
    glTranslatef(0.2, 0,0 );///(3)往右移動, 掛在身體的右肩
    glRotatef(angle[1], 0,0,1);///(2)旋轉
    glTranslatef(0.28, 0,0);///(1)往右推,把茶壼的柄,放到中心,變 轉動軸

    glColor3f(255,0,0);///紅色
    glutSolidTeapot( 0.2 );///手臂

    glPushMatrix();
    glTranslatef(0.2, 0,0 );
    glRotatef(angle[2], 0,0,1);
    glTranslatef(0.28, 0,0);

    glColor3f(255,0,0);///紅色
    glutSolidTeapot( 0.2 );///手臂
    glPopMatrix();
    glPopMatrix();



   glPushMatrix();
    glTranslatef(-0.2, 0,0 );///(3)往右移動, 掛在身體的右肩
    glRotatef(angle[3], 0,0,1);///(2)旋轉
    glTranslatef(-0.28, 0,0);///(1)往右推,把茶壼的柄,放到中心,變 轉動軸

    glColor3f(255,0,0);///紅色
    glutSolidTeapot( 0.2 );///手臂

    glPushMatrix();
    glTranslatef(-0.2, 0,0 );
    glRotatef(angle[4], 0,0,1);
    glTranslatef(-0.28, 0,0);

    glColor3f(255,0,0);///紅色
    glutSolidTeapot( 0.2 );///手臂
    glPopMatrix();
    glPopMatrix();

    glutSwapBuffers();
    ///angle++;
}
    void motion(int x,int y)
    {
        angle[joinID]=x;
        ///if(joinID==1) angle1=x;
        ///if(joinID==2) angle2=x;
        ///if(joinID==3) angle3=x;
        ///if(joinID==4) angle4=x;
        display();
    }
    void keyboard(unsigned char key,int x,int y)
    {
        if(key=='1') joinID=1;
        if(key=='2') joinID=2;
        if(key=='3') joinID=3;
        if(key=='4') joinID=4;
        display();
    }
int main(int argc, char**argv)
{
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
    glutCreateWindow("week11 06160396");
    glutIdleFunc(display);///Now!!!!
    glutDisplayFunc(display);
    glutMotionFunc(motion);
    glutKeyboardFunc(keyboard);
    glutMainLoop();
}
