2020電腦圖學B: Sunnnnnnnnnnnnnn

第三週哦哦哦哦哦

複習

到 -> http://www.cmlab.csie.ntu.edu.tw/~jsyeh/3dcg10/
下載data . win32(解壓縮) . glut32.dll
之後把data裡面的資料夾與glut32.dll放到win32裡
打開裡面的shape~

No.1

複習上個禮拜的茶壺 Teapot

順便考慮一下晚餐要吃什麼?

新增一行程式碼是這週的作業:滑鼠

關於滑鼠的程式碼
下面的Printf是讓我們知道"值"

第一行

0是左鍵 1是中鍵 2是右鍵

第二行

0是壓下1是彈起

第三四行是x,y軸

這是改完以後的程式碼

把座標值改好

滑鼠點哪裡,茶壺就到哪裡

茶裡查理

...?

-----

程式碼:

#include <GL/glut.h>

#include <stdio.h>

float teapotX=0, teapotY=0;

void display()

{

glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

glPushMatrix();

glTranslatef(teapotX, teapotY, 0);

glutSolidTeapot( 0.3 );

glPopMatrix();

glutSwapBuffers();

}

void mouse(int button, int state, int x, int y)

{

printf("%f %f\n", (x-150)/150.0, (y-150)/150.0);

teapotX= (x-150)/150.0;

teapotY= -(y-150)/150.0;

}

int main(int argc,char**argv)

{

glutInit(&argc,argv);

glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

glutCreateWindow("Week03");

glutDisplayFunc(display);

glutMouseFunc(mouse);

glutMainLoop();

}

-----

No.2

Main程式不變

以下的程式碼可以自己畫出想要的圖形

先在小黑窗點想要的圖案

複製座標位置貼到程式碼

再跑一次就會出來了哦水拉!

-----

程式碼:

#include <GL/glut.h>

#include <stdio.h>

void display()

{

glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

glBegin(GL_POLYGON);

glVertex2f((163-150)/150.0, - (35-150)/150.0);

glEnd();

glutSwapBuffers();

}

void mouse(int button, int state, int x, int y)

{

if(state==GLUT_DOWN)

{

printf("glVertex2f((%d-150)/150.0, - (%d-150)/150.0);\n",x,y);

}

int main(int argc, char**argv)

{

glutInit(&argc,argv);

glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

glutCreateWindow("Week03");

glutDisplayFunc(display);

glutMouseFunc(mouse);

glutMainLoop();
