WEEK12

WEEK12

作業 1

jsyeh.org/3dcg10下載win32.zip / data.zip / glut32.dll

再將data.zip / glut32.dll放進windows資

作業 2

開啟新檔案 

貝殼

刪除main程式

用

freeglut
openg32
glu32
gdi32
winmm

作業 3

加入data資料夾 / freeglut.dll / glm.c / glm.h / transformation.c
將tranformation.c改檔名為myOBJ.cpp / glm.c改為glm.cpp

改程式碼

#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);
    }
    glmDraw(pmodel, GLM_SMOOTH | GLM_MATERIAL);

    //剪貼Transformation.c中程式

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



作業 4

***打光、深度、旋轉角度***

#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();
        glRotatef(150, 0,1,0); 
        glmDraw(pmodel, GLM_SMOOTH | GLM_MATERIAL);
    glPopMatrix();
    glutSwapBuffers();
}
GLfloat pos[]={0.0,0.0,-1.0,0.0};
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);
    glEnable(GL_LIGHT0);
    glEnable(GL_LIGHTING);
    glEnable(GL_DEPTH_TEST);  //深度測試

 //以上為打光

    glutMainLoop();
}
