 1.期中考題:jsyeh.org/gl

2.新增專案GLUTweek06-0_sample

找宣告、函示

"""宣告

const GLfloat light_diffuse[]  = { 1.0f, 1.0f, 1.0f, 1.0f };

3.week06-1_lighting

新增專案GLUT貼上11行程式碼

""

#include<GL/glut.h>

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}

//這裡放打光的8行宣告

int main(int argc,char*argv[])

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("week02_color_teapot");

    glutDisplayFunc(display);

    //這裡放打光的12+2行程式

    glutMainLoop();

}

""

執行時是背光要改光線位置

改const GLfloat light_position[] = { 2.0f, 5.0f, 5.0f, 0.0f };=>const GLfloat light_position[] = { 2.0f, 5.0f, -5.0f, 0.0f };

改const GLfloat light_diffuse[]  = { 1.0f, 1.0f, 1.0f, 1.0f };=>const GLfloat light_diffuse[]  = { 1.0f, 1.0f, 0.0f, 1.0f };

4.https://jsyeh.org/3dcg10/下載soure data win32

開Light Material

5.week06-2_lighting_glNormal3f

新增專案GLUT貼上week06-1_lighting，加上四邊形

6.week06-3_glm_obj_model

新增專案GLUT，貼上11行，從soure.zip有3個程式檔transformation.c glm.h glm.c解壓縮

在專案設定把glm.h放到桌面\week06-3_glm_obj_model，把glm.c放到\week06-3_glm_obj_model，改檔名glm.cpp，在專案里案右鍵Add Files，加入glm.cpp，把data放到freeglut的bin
