step01-1

到https://jsyeh.org/3dcg10,下載windows.zip and data.zip

        -windows.zip 解壓縮 下載 \windows\Transformation.exe

        -data.zip         解壓縮 下載\windows\data\有3D模型

開始執行

step02-1

CodeBlocks-File_New_Project,GLUT專案，檔名為week03-1_translate

打開上禮拜的Blog利用上次寫的(茶壺)程式，把它複製上去

#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("week03");

    glutDisplayFunc(display);

    glutMainLoop();

}

step02-2

用GitHub Gist功能，新增程式，會照著副檔名來變色。使用Embedded JaveScript的方式，便可把那一橫程式，用HTML模式，插入Blog裡

step02-3

新增程式碼

#include <GL/glut.h>

void display()

{

    glPushMatrix();

        glTranslatef(0.5,0.5,0);

        glutSolidTeapot(0.3);

    glPopMatrix();

    glutSwapBuffers();

}

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

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_RGB|GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("week03");

    glutDisplayFunc(display);

    glutMainLoop();

}

CodeBlocks新增新的專案New-Project-week03-2_translate_mouse

撰寫程式,利用滑鼠可以移動茶壺

#include <GL/glut.h>

float X=0,Y=0,Z=0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glTranslatef(X,Y,Z);

        glutSolidTeapot(0.3);

    glPopMatrix();

    glutSwapBuffers();

}

void mouse(int button,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");

    glutMouseFunc(mouse);

    glutDisplayFunc(display);

    glutMainLoop();

}

step03-1CodeBlocks新增專案New-Profect-week03-3_mouse_homework

利用滑鼠寫程式

#include <GL/glut.h>

#include <stdio.h>

float X=0,Y=0,Z=0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glutSwapBuffers();

}

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

{

    X = (x-150)/150.0;

    Y = (y-150)/150.0;

    if(state==GLUT_DOWN)printf("    glVertex2f(%.2f,%.2f);\n",X,Y);

}

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

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_RGB|GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("week03");

    glutMouseFunc(mouse);

    glutDisplayFunc(display);

    glutMainLoop();

}
