課堂作業1:

1.下載win32,data,glut32.dll,source(去jsyeh.org/3dcg10載)

2.解壓縮

3.data&dll檔放進去win32裡面

4.在source裡面可以找到各種模型程式碼

課堂作業2:

1.開一個貝殼專案

2.下載win32,data,glut32.dll,source(去jsyeh.org/3dcg10載)

3.解壓縮

4.data&dll檔放進去win32裡面

5.密語:freeglut opengl32 glu32 gdi32 winmm

6.將source中的glm.c,glm.h&transformation.c放進專案中

7.再選擇glm.c&transformation.c拉進專案,按執行就好

課堂作業3:

1.另開新檔

2.transformation.c改檔名為myOBJ.cpp,glm.c也改為glm.cpp

3.myOBJ程式碼:

#include <GL/glut.h>
#include "glm.h"
GLMmodel* pmodel = NULL;

void display()
{
    glClearColor(1,0,0,0);///剪貼於transformation.c
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    if (!pmodel) {
        pmodel = glmReadOBJ("data/porsche.obj");
        if (!pmodel) exit(0);
        glmUnitize(pmodel);
        glmFacetNormals(pmodel);
        glmVertexNormals(pmodel, 90.0);
    }

    glmDraw(pmodel, GLM_SMOOTH | GLM_MATERIAL);

    glutSwapBuffers();
}
int main(int argc, char**argv)
{
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
    glutCreateWindow("GLM model is great!");
    glutDisplayFunc(display);

    glutMainLoop();
}

課堂作業4:

將作業2的物體加上深度和打光

程式碼:

#include <GL/glut.h>

#include "glm.h"

GLMmodel* pmodel = NULL;

void display()

{

    glClearColor(1,0,0,0);

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    if (!pmodel) {

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

        if (!pmodel) exit(0);

        glmUnitize(pmodel);

        glmFacetNormals(pmodel);

        glmVertexNormals(pmodel, 90.0);

    }

    glPushMatrix();///讓物體停止不動

        glRotatef(120,0,1,0);///旋轉角度

        glmDraw(pmodel, GLM_SMOOTH | GLM_MATERIAL);

    glPopMatrix();

    glutSwapBuffers();

}

GLfloat pos[] = { 0.0, 0.0, -1.0, 0.0 };///光照的位置

int main(int argc, char**argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("GLM model is great!");

    glutDisplayFunc(display);

    glLightfv(GL_LIGHT0, GL_POSITION, pos);///打光

    glEnable(GL_LIGHT0);

    glEnable(GL_LIGHTING);

    glEnable(GL_DEPTH_TEST);///深度測試

    glutMainLoop();

}
