Week13

主題：如何處理GLUT .cbp 專案檔 的設定 (執行目錄、include/lib目錄、link lib檔)

Step1:原先顯示cbp.檔案，無法直接開啟→File Associations(副檔名）→去Settings-Environment-Manage-把cbp.勾起來

Step2:加wav聲音檔，

#include "mmsystem.h"

PlaySoundA("ccheer.wav",NULL,SND_ASYNC);(

Step3:讀入模組，把mtl.obj.檔or老師給的data裡的mtl.obj.檔到專案檔裡→source的glm.c要改成glm.cpp ；glm.h到專案檔

Step4:開啟CodeBlocks→專案Add files→glm.cpp開啟

Step5:打光函示＆模組程式碼
#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 };

    glMaterialfv(GL_FRONT, GL_SHININESS, high_shininess);

    glutMainLoop();
