STEP1:http://www.cmlab.csie.ntu.edu.tw/~jsyeh/3dcg10/進入

開啟projection.exe

STEP2:開啟Codeblock

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();
}

STEP3:照出顏色

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();
}

STEP4:利用運鏡讓他有旋轉的效果

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();
}

STEP4:最後調整攝影機視角

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(); }
