內含OBJ 模型 ( maya )


2. 開啟 Notepad++ :

















#include<GL/glut.h>
#include "glm.h"
GLMmodel * model= NULL;
void display()
{
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    if(model==NULL) model=glmReadOBJ("data/Al.obj");
    glmUnitize(model);
    glmFacetNormals(model);
    glmVertexNormals(model,90);
    glmDraw(model,GLM_SMOOTH | GLM_MATERIAL);

    glutSwapBuffers();
}
int main(int argc, char** argv)
{
    glutInit(&argc,argv);
    glutInitDisplayMode(GLUT_DEPTH | GLUT_DOUBLE);
    glutCreateWindow("made by me");
    glutDisplayFunc(display);
    glutMainLoop();
}

#include<GL/glut.h>
#include "glm.h"
GLMmodel * model= 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(model==NULL) model=glmReadOBJ("data/Al.obj");
    glmUnitize(model);
    glmFacetNormals(model);
    glmVertexNormals(model,90);
    glmDraw(model,GLM_SMOOTH | GLM_MATERIAL);

    glutSwapBuffers();
}
int main(int argc, char** argv)
{
    glutInit(&argc,argv);
    glutInitDisplayMode(GLUT_DEPTH | GLUT_DOUBLE);
    glutCreateWindow("made by me");
    glutDisplayFunc(display);

    glEnable(GL_DEPTH_TEST);



    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();
}

覺得人臉太黑
調亮




發現做錯
if(model==NULL) model=glmReadOBJ("data/Al.obj");
    {
        glmUnitize(model);
    glmFacetNormals(model);
    glmVertexNormals(model,90);
    }

要有{}  (但結果ㄧ樣)
