week03

step01

開啟網站連結.   👉https://jsyeh.org/3dcg10/

下載三個檔案    👉(windows.zip , data.zip , glut32.dll)

解壓縮(務必記得是解壓縮至此!!!)

開啟檔案.   👉Transformation.exe

成果如圖

step02

下載freeglut-MinGW-3.0.0-1.mp.zip

解壓縮檔案到桌面(freeglut)

複製檔案libfreeglut更名成libglut32.a

開啟codeblocks > create new project

點選 GLUT project

next >

儲存到桌面新增資料夾week03 

開啟fleeglut 資料夾

finish~~

step03

新增程式碼

#include <GL/glut.h>

void display()

{

    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(); 

}

成果如圖 出現茶壺

step04

修改並新增程式碼

#include <GL/glut.h>

void display()

{

    glPushMatrix();

        glTranslatef(0.5 , 0 , 0);

        glutSolidTeapot(0.3);

    glPopMatrix();

    glutSwapBuffers();

}

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

{

    glutInit(&argc, argv); 

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

   

    glutCreateWindow("GLUT Shapes");

    glutDisplayFunc(display); 

    glutMainLoop(); 

}

成果如圖 茶壺向右移動了

step05

修改並新增程式碼

#include <GL/glut.h>

void display()

{

    glPushMatrix();

        glTranslatef(0.5 , 0 , 0);

        glutSolidTeapot(0.3);

    glPopMatrix();

    glutSwapBuffers();

}

#include <stdio.h>

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

{

    printf ("%d %d %d %d\n",botton , state , x , y);

}

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

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week03");

    glutDisplayFunc(display);

    glutMouseFunc(mouse);

    glutMainLoop();

}

成果如圖 點按滑鼠左右鍵會跑出相對應座標

step06

修改並新增程式碼

#include <GL/glut.h>

float X=0,Y=0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );

    glPushMatrix();

        glTranslatef( X , Y , 0);

        glutSolidTeapot(0.3);

    glPopMatrix();

    glutSwapBuffers();

}

#include <stdio.h>

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

{

    X = (x-150)/150.0;

    Y = -(y-150)/150.0;

}

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

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week03");

    glutDisplayFunc(display);

    glutMouseFunc(mouse);

    glutMainLoop();

}

成果如圖 茶壺可以隨滑鼠移動

step08

開啟codeblocks > create new project

點選 GLUT project

儲存到桌面新增資料夾 week03_mouse

step09

修改並新增程式碼

#include <GL/glut.h>

float X=0,Y=0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );

    glPushMatrix();

        glTranslatef( X , Y , 0);

        glutSolidTeapot(0.3);

    glPopMatrix();

    glutSwapBuffers();

}

#include <stdio.h>

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

{

    float X = (x-150)/150.0;

    float Y = -(y-150)/150.0;

    if(state==GLUT_DOWN){

        printf ("   glVertex2f(%.3f, %.3f);\n", X, Y);

    }

}

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

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week03");

    glutDisplayFunc(display);

    glutMouseFunc(mouse);

    glutMainLoop();

}

step10

修改並新增程式碼

#include <GL/glut.h>

float X=0,Y=0;

void display()

{

    glBegin(GL_POLYGON);

    glVertex2f(-0.300, 0.747);

    glVertex2f(-0.520, 0.747);

    glVertex2f(-0.640, 0.520);

    glVertex2f(-0.667, 0.447);

    glVertex2f(-0.147, 0.747);

    glVertex2f(-0.260, 0.753);

    glEnd();

    glutSwapBuffers();

}

#include <stdio.h>

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

{

    float X = (x-250)/250.0;

    float Y = -(y-250)/250.0;

    if(state==GLUT_DOWN){

        printf ("   glVertex2f(%.3f, %.3f);\n", X, Y);

    }

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

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week03");

    glutDisplayFunc(display);

    glutMouseFunc(mouse);

    glutMainLoop();

}

成果如圖

滑鼠點擊過後會生成座標
