week12_3D Model匯入OpenGL_呂登祐

1.匯入模型
2.6行程式碼

01
測試windows.7zip
開啟Transformation.exe測試轉動和移動

02做設定

1.新new project-GLUT

2.#include "glm.h"

3.把glm.c改副檔名改成glm.cpp

4.把transformation.c裡面6行code複製到專案程式裡面(搜尋glm)

程式碼入下圖

#include "glm.h"

GLMmodel* pmodel = NULL;

int main()

{

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

    glmUnitize(pmodel);

glmFacetNormals(pmodel);

glmVertexNormals(pmodel, 90.0);

}

5.執行出現小視窗

6.增加頭尾設定

#include "glm.h"

GLMmodel* pmodel = NULL;

void display()

{

    glmDraw(pmodel, GLM_SMOOTH | GLM_MATERIAL);

    glFlush();

}

int main(int argc,char**argv)

{

    glutInit(&argc, argv);

    glutCreateWindow("GLUT");

    glutDisplayFunc(display);

    pmodel = glmReadOBJ("porsche.obj");

    glmUnitize(pmodel);

glmFacetNormals(pmodel);

glmVertexNormals(pmodel, 90.0);

glutMainLoop();

}

06.讓模型打光

#include "glm.h"

GLMmodel* pmodel = NULL;

void display()

{

    GLfloat pos[] = { 0.0, 0.0, -1.0, 0.0 };

    glLightfv(GL_LIGHT0, GL_POSITION, pos);

    glEnable(GL_LIGHT0);

    glEnable(GL_LIGHTING);

    glEnable(GL_DEPTH_TEST);

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glmDraw(pmodel, GLM_SMOOTH | GLM_MATERIAL);

    glFlush();

}

int main(int argc,char**argv)

{

    glutInit(&argc, argv);

    glutCreateWindow("GLUT");

    glutDisplayFunc(display);

    pmodel = glmReadOBJ("porsche.obj");

    glmUnitize(pmodel);

glmFacetNormals(pmodel);

glmVertexNormals(pmodel, 90.0);

glutMainLoop();

}
