week11

1.在moodle把windows.source.data下載，然後進行解壓縮

2.建立自己的transformation.exe-

  (1)開啟codeblock-File-Project-GLUT專案(設定好freeglut)

  (2)將解壓縮完的glm.c glm.h transformation.c拉到桌面week11

  (3)將glm.c改檔名變成glm.cpp glm.h放同目錄 transformation.c內容放到main.cpp

3.把 glm.cpp放入專案，左邊project裡，Add檔案，glm.cpp加入

4.打光:

#include "glm.h"

GLMmodel* pmodel = NULL;

void drawmodel(void)

{

    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);

}

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    drawmodel();

    glutSwapBuffers();

}
