TRT複習
但要先把CBP檔設定好
然後像11周一樣把模型叫出來然後打光

#include<GL/glut.h>
#include "glm.h"
GLMmodel * model=NULL;
//打光的第0步,宣告陣列,裡面有光的屬性值

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, 3.0f, -5.0f, 0.0f };///照光方向數值

const GLfloat mat_specular[] = { 1.0f, 1.0f, 1.0f, 1.0f };
const GLfloat high_shininess[] = { 100.0f };

void display()
{

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_DOUBLE|GLUT_DEPTH);
glutCreateWindow("Myself");

///打光也需要 3D的 depth test

叫多個OBJ，然後用滑鼠控制轉動
