❤攝影機的運鏡❤

1.先下載老師給的data,win32,glut32.dll,source

   http://www.cmlab.csie.ntu.edu.tw/~jsyeh/3dcg10/

2.將window.zip解壓縮到window資料夾，複製glut32.dll到window資料夾裡

   

3.打開Projection.exe來試試看運鏡

❤實作攝影機的運鏡❤

4.先開啟freeglut windows網站 https://www.transmissionzero.co.uk/software/freeglut-devel/

然後下載Download freeglut 3.0.0 for MinGW ，

然後解壓縮然後打開lib資料夾，複製貼上libfreeglut.a，把複製的改名為libglut32.a

5.打開codeblack先建一個glut然後開啟執行，並把本來的程式刪光光

6.把source資料夾裡的glm.c,glm.h,projection.c複製到week15的資料夾

   並把glm.c改成glm.cpp

7.新增glm.cpp進來

  (用note++打開projection.c參考)

8.把window的data複製到freeglut的bin資料夾

9.打出程式碼

------------程式碼------------

#include <GL/glut.h>

#include "glm.h" ///for glmReadOBJ(), glmDraw(), glmUnitized()....

GLMmodel * pmodel=NULL;///NOW

void drawmodel(void)

{

    if (!pmodel) {

pmodel = glmReadOBJ("data/al.obj");

if (!pmodel) exit(0);

glmUnitize(pmodel);

glmFacetNormals(pmodel);

glmVertexNormals(pmodel, 90.0);

    }

    glmDraw(pmodel, GLM_SMOOTH | GLM_MATERIAL);

}

void display(void)

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    drawmodel();

    glutSwapBuffers();

}

int main(int argc, char**argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutInitWindowSize(500,500);

    glutCreateWindow("week15");

    glutDisplayFunc(display);

    glutMainLoop();

}

 

(會做出一個白色的人)

10.再增加色彩(打光)程式碼

------------程式碼------------

#include <GL/glut.h>

#include "glm.h" ///for glmReadOBJ(), glmDraw(), glmUnitized()....

GLMmodel * pmodel=NULL;///NOW

void drawmodel(void)

{

    if (!pmodel) {

pmodel = glmReadOBJ("data/al.obj");

if (!pmodel) exit(0);

glmUnitize(pmodel);

glmFacetNormals(pmodel);

glmVertexNormals(pmodel, 90.0);

    }

    glmDraw(pmodel, GLM_SMOOTH | GLM_MATERIAL);

}

void display(void)

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    drawmodel();

    glutSwapBuffers();

}

int main(int argc, char**argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutInitWindowSize(500,500);

    glutCreateWindow("week15");

    glutDisplayFunc(display);

    GLfloat light_pos[] = { 0.0, 0.0, -1.0, 0.0 };///NOW2 打光的位置

    glEnable(GL_DEPTH_TEST);///NOW2 有立體的功能

    glEnable(GL_LIGHT0);    ///NOW2 打光後變立體的彩色的

    glEnable(GL_LIGHTING);  ///NOW2 打光後變立體的彩色的

    glLightfv(GL_LIGHT0, GL_POSITION, light_pos);///NOW2 打光的位置

    glutMainLoop();

}

11.再增加運鏡的程式碼

------------程式碼------------

#include <GL/glut.h>

#include "glm.h" ///for glmReadOBJ(), glmDraw(), glmUnitized()....

GLMmodel * pmodel=NULL;///NOW

void drawmodel(void)

{

    if (!pmodel) {

pmodel = glmReadOBJ("data/al.obj");

if (!pmodel) exit(0);

glmUnitize(pmodel);

glmFacetNormals(pmodel);

glmVertexNormals(pmodel, 90.0);

    }

    glmDraw(pmodel, GLM_SMOOTH | GLM_MATERIAL);

}

void display(void)

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    drawmodel();

    glutSwapBuffers();

}

#include <math.h>

float eyeX=1, eyeY=0, eyeZ=0;

void timer(int t)///NOW3

{

    glutTimerFunc(33, timer, t+1);///NOW3

    float angle=t/180.0*3.1415926;///NOW3 算出一個角度

    eyeX=cos(angle); eyeZ=sin(angle);///NOW3

    glMatrixMode(GL_MODELVIEW);///NOW3

    glLoadIdentity();///NOW3

    gluLookAt(eyeX, eyeY, eyeZ, ///NOW3 LookAt的 eye

              0.0, 0.8, 0.0, ///NOW3 LookAt的 center

              0, 1, 0);///NOW3 LookAt的 up

    glutPostRedisplay();///NOW3 Re-display

}

int main(int argc, char**argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutInitWindowSize(500,500);

    glutCreateWindow("week15");

    glutDisplayFunc(display);

    glutTimerFunc(33, timer, 0);///NOW3

    GLfloat light_pos[] = { 0.0, 0.0, -1.0, 0.0 };///NOW2 打光的位置

    glEnable(GL_DEPTH_TEST);///NOW2 有立體的功能

    glEnable(GL_LIGHT0);    ///NOW2 打光後變立體的彩色的

    glEnable(GL_LIGHTING);  ///NOW2 打光後變立體的彩色的

    glLightfv(GL_LIGHT0, GL_POSITION, light_pos);///NOW2 打光的位置

    glutMainLoop();

}

❤計時器❤

1.先開啟freeglut windows網站 
https://www.transmissionzero.co.uk/software/freeglut-devel/

然後下載Download freeglut 3.0.0 for MinGW ，

然後解壓縮然後打開lib資料夾，複製貼上libfreeglut.a，把複製的改名為libglut32.a

2.打開codeblack，建立一個project，然後建立glut開啟執行

  (把原本的程式碼刪光光)

3.在Google查詢http://billor.chsh.chc.edu.tw/sound/p.htm 找聲音下載

(下載完後丟到freeglut的bin資料夾)

4.把老師在http://120.125.89.81/給的程式碼貼上(可以發出聲音，1秒一次)

-------------(程式碼)-----------------

#include <GL/glut.h>

#include <mmsystem.h>///NOW (0)發聲音

void display()

    glutSwapBuffers();

}

void timer(int t)///NOW (2)

{

    glutTimerFunc(1000, timer, 0);///NOW2
