Week 06 打光&模型

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

2.Examples下載win32、data

3.other examples下載glut32.dll

4.解壓縮windows資料夾

5.將data壓縮檔打開(不要解壓縮)，直接拖曳到windows資料夾中

6.將glut32.dll放入windows資料夾中

7.打開Light Material.exe即可使用

茶壺打光程式碼

#include<GL/glut.h>

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 display()

{
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}



int main(int argc,char**argv)



{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("WeekQ3");

    glutDisplayFunc(display);

    glClearColor(1,1,1,1);
    glEnable(GL_CULL_FACE);
    glCullFace(GL_BACK);

    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();


}

把保時捷加入程式:

1.從Source.zip中尋找Tranformation.c 解壓縮出來後用NotePad++

Ctlr+S尋找glm後按找下一個。(GLMmodel* pmodel = NULL;)

再按找下一個。

(if (!pmodel) {

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

if (!pmodel) exit(0);

glmUnitize(pmodel);

glmFacetNormals(pmodel);

glmVertexNormals(pmodel, 90.0);

    })

貼上下方程式碼之後開始置放檔案。

2.將Source.zip中的glm.c、glm.h解壓縮出來(打開ZIP直接拉出來)

放到Codeblocks專案的資料夾裡面(最外層)，再把glm.c改名為glm.cpp。

3.將glm.cpp加入到Source裡(左邊Workspace中的專案名稱點選右鍵→Add files)

4.將data資料夾打開(不解壓縮)，直接拉進freeglut的bin中

#include<GL/glut.h>
#include "glm.h"

GLMmodel* pmodel = NULL;

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 display()

{
    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();
