Week 04 吳東峻

課堂作業一
作業互評上傳
用7-Zip解壓縮
小心別用Adobe打開

挑出你認為最好的5張上傳










課堂作業二

從網址下載: sorce , date , win32 ,glut32.dll ( jsyeh.org/3dcg10 )

解壓縮win32

把 data 打開，將裡面的資料夾複製到上面解壓縮後的window32資料夾

再將 glut32.dll 移至window32資料夾

執行Transformation

soccerball

AI Capone

F16 Jet

Dolphins

Flower

Rose

點glTranslatef 移動

點glRotatef旋轉

點glScalef縮放大小



課堂作業三
Mouse 操作

茶壺會一直移動

程式碼:

#include <GL/glut.h>

void display()

{

    glClearColor(1,1,0,1);

    glClear(GL_COLOR_BUFFER_BIT);

    glTranslatef(0, -0.1, 0);///按一下往下0.1

    glColor3f(1,0,0);

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}

int main(int argc, char**argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("Hello");

    glutDisplayFunc(display);

    glutMainLoop();

}

點到哪跑到哪


程式碼

#include <GL/glut.h>
float nowX=0, nowY=0;
void mouse(int button, int state, int x,int y)
{
    nowX = (x-150)/150.0; nowY = -(y-150)/150.0;
}

void display()
{
    glClearColor(1,1,0,1);
    glClear(GL_COLOR_BUFFER_BIT);
    glPushMatrix();///備份Mstrix
    glTranslatef(nowX,nowY,0);///怎麼越動越多??
    glColor3f(1,0,0);
    glutSolidTeapot(0.3);
    glPopMatrix();///還原Matrix
    glutSwapBuffers();
}

int main(int argc,char**argv)
{
    glutInit(&argc,argv);
    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
    glutCreateWindow("Hello 3D");
    glutDisplayFunc(display);
    glutMouseFunc(mouse);
    glutMainLoop();

}

課堂作業四

Mouse進階
畫出圓圈 隨滑鼠移動並顯示座標

程式碼
#include <GL/glut.h>
#include <stdio.h>
#include <math.h>
float nowX=0, nowY=0;
void mouse(int button, int state, int x,int y)
{
    nowX = (x-150)/150.0; nowY = -(y-150)/150.0;
    printf("glTranslatef(%f,%f, 0);\n", nowX, nowY);
}

void display()
{
    glClearColor(1,1,0,1);
    glClear(GL_COLOR_BUFFER_BIT);
    glPushMatrix();///備份Mstrix
    glTranslatef(nowX,nowY,0);///怎麼越動越多??
    glColor3f(1,0,0);
    ///glutSolidTeapot(0.3);
    glBegin(GL_POLYGON);
        for(float angle=0; angle<3.14159235358979*2; angle+=0.1){
            glVertex2f(0.2*cos(angle), 0.2*sin(angle));
        }
    glEnd();
    glPopMatrix();///還原Matrix
    glutSwapBuffers();
}

int main(int argc,char**argv)
{
    glutInit(&argc,argv);
    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
    glutCreateWindow("Hello 3D");
    glutDisplayFunc(display);
    glutMouseFunc(mouse);
    glutMainLoop();
}
