Week 13 X+7 的筆記(寫檔、讀檔，控制關節，動作內插)

1.產生一個file(Ctrl+Shift+N)

#include <stdio.h>
int main()
{
    FILE * fout=fopen("output.txt","w+");
    printf("Hello world\n");
    fprintf(fout,"Hello world\n");
}


把運動的角度數值印出來

#include <stdio.h>
float angle=0,angle2=10,angle3=90;
int main()
{
    FILE * fout=fopen("output.txt","w+");
    //printf("Hello world\n");
    fprintf(fout,"%.3f,%.3f,%.3f\n",angle,angle2,angle3);
}

2.開Project打程式碼

#include <Gl/glut.h>
#include <mmsystem.h>
#include "CMP3_MCI.h"
#include <stdio.h>
FILE * fout=NULL;
CMP3_MCI myMP3;
float angle=0;
int oldX=0;
float alpha=0;
void mouse(int button,int state,int x,int y)
{
    oldX=x;
}
void motion(int x,int y)
{
    angle += x-oldX;
    oldX=x;
    if(fout==NULL){
    fout = fopen("output.txt","w+");
    }
    fprintf(fout,"%.3f\n",angle);
    printf("%.3f\n",angle);
    glutPostRedisplay();
}
void display()
{
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    glPushMatrix();
        glutSolidTeapot(0.3);
        glPushMatrix();
        glTranslatef(0.4,0,0);
        glRotatef(angle,0,0,1);
        glTranslatef(0.4,0,0);
        glutSolidTeapot(0.3);
        glPopMatrix();
    glPopMatrix();
    glutSwapBuffers();
}
const GLfloat light_ambient[]  = { 0.0f, 0.0f, 0.0f, 1.0f };
const GLfloat light_diffuse[]  = { 1.0f, 1.0f, 1.0f, 1.0f };
const GLfloat light_specular[] = { 1.0f, 1.0f, 1.0f, 1.0f };
const GLfloat light_position[] = { 2.0f, 5.0f, 5.0f, 0.0f };
const GLfloat mat_ambient[]    = { 0.7f, 0.7f, 0.7f, 1.0f };
const GLfloat mat_diffuse[]    = { 0.8f, 0.8f, 0.8f, 1.0f };
const GLfloat mat_specular[]   = { 1.0f, 1.0f, 1.0f, 1.0f };
const GLfloat high_shininess[] = { 100.0f };

/*void timer(int t)
{
    glutTimerFunc(50,timer,t+1);
    alpha = t/100.0;
    angle = alpha*90 + (1-alpha)*0;
    glutPostRedisplay();
    ///PlaySound("Shot.wav",NULL,SND_ASYNC);
}*/
int main(int argc, char *argv[])
{
    myMP3.Load("MJThriller.mp3");
    myMP3.Play();
    ///PlaySound("BigDog.mp3", NULL, SND_ASYNC);
    glutInit(&argc, argv);
    glutInitWindowSize(640,480);
    glutInitWindowPosition(10,10);
    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);
    glutCreateWindow("GLUT Shapes");
  glutMouseFunc(mouse);
    glutMotionFunc(motion);
    glutDisplayFunc(display);
    /*glutTimerFunc(1000,timer,0);*/

    glClearColor(1,1,1,1);
    glEnable(GL_DEPTH_TEST);
    glDepthFunc(GL_LESS);
    glEnable(GL_LIGHT0);
    glEnable(GL_NORMALIZE);
    glEnable(GL_COLOR_MATERIAL);
    glEnable(GL_LIGHTING);
    glLightfv(GL_LIGHT0, GL_AMBIENT,  light_ambient);
    glLightfv(GL_LIGHT0, GL_DIFFUSE,  light_diffuse);
    glLightfv(GL_LIGHT0, GL_SPECULAR, light_specular);
    glLightfv(GL_LIGHT0, GL_POSITION, light_position);
    glMaterialfv(GL_FRONT, GL_AMBIENT,   mat_ambient);
    glMaterialfv(GL_FRONT, GL_DIFFUSE,   mat_diffuse);
    glMaterialfv(GL_FRONT, GL_SPECULAR,  mat_specular);
    glMaterialfv(GL_FRONT, GL_SHININESS, high_shininess);
    glutMainLoop();
    return EXIT_SUCCESS;
}
