Week13

一、關節擺動

(1)開新檔：codeblocks>file>project>Console application

(2)打出程式碼

(3)看到有新增檔案在  C:\Users\user\Desktop\week13_file\file





程式碼：

#include <stdio.h>
FILE * fout=NULL;
int main()
{
    fout = fopen("filename.txt", "w+");
    for(int i=0;i<20;i++){
        fprintf(fout,"Hello World\n");

    }
}

二、開始製作機器人

(1)開啟GL專案

(2)打出程式碼

程式碼：

#include <GL/glut.h>

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glutSolidTeapot( 0.3 );

    glutSwapBuffers();

}

int main(int argc, char**argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    ///glutInitWindowSize(600,600);///我們可以開很大的視窗

    glutCreateWindow("week 13 motion TRT angle file");

    glutDisplayFunc(display);

    glutMainLoop();

}

#include <GL/glut.h>

float angle[20];///NOW

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();///body

        glColor3f(1,1,1);///white

        glutSolidTeapot( 0.3 );///body

        glPushMatrix();///right Arm

            glTranslatef(0.18, 0, 0);///(3)掛到肩上

            glRotatef(angle[1], 0,0,1);///(2)轉動 ///NOW

            glTranslatef(0.18, 0, 0);///(1)改變旋轉中心,放到中心

            glColor3f(1,0,0);///red

            glutSolidTeapot( 0.2 );///right upper arm

        glPopMatrix();

    glPopMatrix();

    glutSwapBuffers();

}

int oldX;///NOW

void mouse(int button, int state, int x, int y)///NOW

{

    oldX = x;///NOW

}

void motion(int x, int y)///NOW

{

    angle[1] += (x-oldX);///NOW

    oldX = x;///NOW

    display();///NOW

}

int main(int argc, char**argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    ///glutInitWindowSize(600,600);///我們可以開很大的視窗

    glutCreateWindow("week 13 motion TRT angle file");

    glutMouseFunc(mouse);///NOW

    glutMotionFunc(motion);///NOW

    glutDisplayFunc(display);

    glutMainLoop();
