week15電腦圖學

4z week15

1.開CodeBlocks->建立新的Empty File week15-1_PlaySound.cpp 並在在settings->compiler加入winmm

#include <windows.h>

#include <stdio.h>

int main()

{

    printf("PlaySound()\n");

    PlaySound("07042111.wav",NULL,SND_SYNC);

    printf("PlaySound()之後\n");

}

2..開 CodeBlocks/empty file-->week15_SND_SNTC_ASNYC.cpp

直接播

#include <windows.h>

#include <stdio.h>

int main()

{

    PlaySound("do.wav",NULL,SND_SYNC);///ASYNC不等待

    PlaySound("re.wav",NULL,SND_SYNC);

    PlaySound("mi.wav",NULL,SND_SYNC);

}

等待

#include <windows.h>

#include <stdio.h>

int main()

{

    PlaySound("07042111.wav",NULL,SND_ASYNC);///ASYNC不等待

    while(1){

       printf("請輸入數字: ");

        int N;

        scanf("%d",&N);

        if (N==1) PlaySound("do.wav",NULL,SND_ASYNC);

        if (N==2) PlaySound("re.wav",NULL,SND_ASYNC);

        if (N==3) PlaySound("mi.wav",NULL,SND_ASYNC);

    }

}

3.開 CodeBlocks/empty file-->week15_MP3.cpp並到moodle 下載CMP3_MCI.h

#include <stdio.h>

#include "CMP3_MCI.h"

CMP3_MCI mp3;

nt main()

{

    mp3.Load("009160986.mp3");

    mp3.Play();

    printf("隨便等你輸入數字,程式就卡住了 : ");

    int N;///為了程式不要結束

    scanf("%d",&N);

}

4.myWrite()會寫一行，myRead()會讀一行,然後要在keyboard()裡面新增動作s，當按下s後會儲存當前手臂的位置

#include <GL/glut.h>

#include <stdio.h>

float angle[20],oldX=0;

int angleID=0;

FILE * fout = NULL, * fin = NULL;

void myWrite(){

    if(fout == NULL) fout = fopen("file.txt", "w+");

    for(int i=0 ; i<20 ; i++){

        printf(" %.1f ", angle[i]);

        fprintf(fout, " %.1f ",angle[i]);

    }

    printf("\n");

    fprintf(fout,"\n");

}

void myread(){

    if(fout != NULL){   fclose(fout); fout=NULL;  }

    if(fin == NULL) fin = fopen("file.txt", "r");

    for(int i=0 ; i<20 ; i++){

        fscanf(fin, "%f",&angle[i]);

    }

    glutPostRedisplay();

}

void mouse(int Button, int state, int x, int y){

    oldX= x;

}

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

    if(key=='s') myWrite(); ///調好動作再存檔

    if(key=='r') myread();

    if(key=='0') angleID=0;

    if(key=='1') angleID=1;

    if(key=='2') angleID=2;

    if(key=='3') angleID=3;

}

void motion(int x,int y){

    angle[angleID] += (x-oldX);

    ///myWrite();

    oldX = x;

    glutPostRedisplay();

}

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glColor3f(1,1,1);

    glRectf(0.3,0.5,-0.3,-0.5);

    glPushMatrix();

        glTranslatef(0.3,0.4,0);

        glRotatef(angle[0],0,0,1);

        glTranslatef(-0.3,-0.4,0);

        glColor3f(1,0,0);

        glRectf(0.3,0.5,0.7,0.3);

        glPushMatrix();

            glTranslatef(0.7,0.4,0);

            glRotatef(angle[1],0,0,1);

            glTranslatef(-0.7,-0.4,0);

            glColor3f(0,1,0);

            glRectf(0.7,0.5,1,0.3);

        glPopMatrix();

    glPopMatrix();

    glPushMatrix();

        glTranslatef(-0.3,0.4,0);

        glRotatef(angle[2],0,0,1);

        glTranslatef(0.3,-0.4,0);

        glColor3f(1,0,0);

        glRectf(-0.3,0.5,-0.7,0.3);

        glPushMatrix();

            glTranslatef(-0.7,0.4,0);

            glRotatef(angle[3],0,0,1);

            glTranslatef(0.7,-0.4,0);

            glColor3f(0,1,0);

            glRectf(-0.7,0.5,-1,0.3);

        glPopMatrix();

    glPopMatrix();

    glutSwapBuffers();

}

int main(int argc, char**argv)

{

    glutInit( &argc, argv );

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    ///glutInitWindowSize(600,600);

    glutCreateWindow("week15-1_angles_TRT_again");

    glutKeyboardFunc(keyboard);

    glutMouseFunc(mouse);

    glutMotionFunc(motion);

    glutDisplayFunc(display);

    glutMainLoop();

}

讓機器人擺動作

1.需要3D Model (glm.h,glm.cpp .obj....)

2.需要切割模型分別讀入

3.使用TRT程式轉動分割後的模型keboard() 切換關節， mouse motion()用滑鼠轉動關節

4.建立一個新GLUT專案 week15_hw_gundam_parts

5.用Notepad++將工作目錄的路徑改成 "."
