week10-1_glutWireCube_myBody_myArm

貼上week09-3 的程式

改寫 void display()改寫一下 呼叫myBody() myArm()

留下wireCube

綠色手臂 紅色是身體

-----------------------------------------------------------------------------------------------------------------------------

#include <GL/glut.h>

void myBody() { ///我的身體

glPushMatrix(); ///備份矩陣

        glColor3f(1, 0, 0);///紅色的

        glutWireCube(0.6);///myBody();

glPopMatrix(); ///還原矩陣

}

void myArm() { ///我的手臂

glPushMatrix();

        glColor3f(0, 1, 0); ///綠色的

        glScalef(1, 0.4, 0.4);///myArm();

        glutWireCube(0.3);

glPopMatrix();

}

void display()

{

glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    myBody(); ///我的身體

    myArm(); ///我的手臂

    glutSwapBuffers();

}

int main(int argc, char*argv[])

{

glutInit(&argc, argv);

glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

glutCreateWindow("week10");

glutMainLoop();

}

-----------------------------------------------------------------------------------------------------------------------------

week10-2_rotate_myArm

加上float angle = 0; #旋轉的角度

-----------------------------------------------------------------------------------------------------------------------------

float angle = 0; ///旋轉的角度

void display()

{

glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    myBody(); ///我的身體

    glPushMatrix();

        glRotatef(angle++, 0, 0, 1); ///旋轉的角度
