Week 3

   HW 1   點.線.面.色彩介紹

主題:點.線.面.色彩
Link:http://jsyeh.ong/3dcg10

步驟1Download (1)data.zip(2)win32.zip(3)glut32.dll

步驟2  1.解壓縮data.zip到window.zip解壓縮出來的資料夾，glut32也丟進去

2.開啟shape.exe

3.右鍵可以改三角形、矩形...等多邊形

   HW2   複習上週茶壺變色

顏色修改後

#include <GL/glut.h>

static void display(void)

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glColor3f(62/255.0,65/255.0,35/255.0); ///顏色(R,G,B)

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}

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

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("GLUT Shapes");

    glutDisplayFunc(display);

    glutMainLoop();

    return EXIT_SUCCESS;

}

   HW3   glBegin函式

每日一字:Vertex頂點、Edge邊

#include <GL/glut.h>

static void display(void)

{

    glBegin(GL_POLYGON);

        glColor3f(1,0,0);  //顏色(R,G,B)

        glVertex3f(0,0,0); //3個浮點數點座標位置(x,y,z)

        glColor3f(0,1,0);

        glVertex3f(1,1,0);

        glColor3f(0,0,1);

        glVertex3f(1,-1,0);

    glEnd();

    glutSwapBuffers();

}

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

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("GLUT Shapes");//視窗名稱可自訂

    glutDisplayFunc(display);///使用display函式

    glutMainLoop();

    return EXIT_SUCCESS;

}
