Week 5_04160373 梁家豪_洞叁倆么_上課筆記

Week 5

HW1_登入Zuvio.com.tw回答Week4問題

HW2_下載glut32

Link:http://jsyeh.ong/3dcg10

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

步驟2開啟Transformation.exe試著縮放,旋轉

HW3_PushMatrix,PopMatrix

#include<gl/glut.h>

void display()

{

    glPushMatrix();//備份

        glTranslatef(0,1,0);

        glutSolidTeapot(0.3);

    glPopMatrix();//還原

    glutSwapBuffers();

}

int main(int argc,char ** argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_RGB|GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("04160373_translate rotate scale");

    glutDisplayFunc(display);

    glutMainLoop();

}

HW4_茶壺移動Translate旋轉Rotate縮放Scale

移動Translate,滑鼠左鍵按住茶壺可以移動它

#include<gl/glut.h>

float mouseX=0,mouseY=0;//滑鼠座標

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);//做清除顏色及深度動作

    glPushMatrix();//備份

        glTranslatef(mouseX,mouseY,0);

        glutSolidTeapot(0.3);

    glPopMatrix();//還原

    glutSwapBuffers();

}

void motion(int x,int y)

{

    mouseX=(x-150)/150.0;

    mouseY= -(y-150)/150.0;

    glutPostRedisplay();//貼一張便利貼Post，更新電腦畫面

}

int main(int argc,char ** argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_RGB|GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("04160373_translate rotate scale");

    glutDisplayFunc(display);

    glutMotionFunc(motion);//移動函式

    glutMainLoop();

}

縮放Scale,滑鼠左鍵按住茶壺可以縮放它

#include<gl/glut.h>

float mouseX=0,mouseY=0;//滑鼠座標

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);//做清除顏色及深度動作

    glPushMatrix();//備份

        glScalef(mouseX,mouseY,0);//縮放函式

        glutSolidTeapot(0.3);

    glPopMatrix();//還原

    glutSwapBuffers();

}

void motion(int x,int y)

{

    mouseX=(x-150)/150.0;

    mouseY= -(y-150)/150.0;

    glutPostRedisplay();//貼一張便利貼Post，更新電腦畫面

}

int main(int argc,char ** argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_RGB|GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("04160373_translate rotate scale");

    glutDisplayFunc(display);

    glutMotionFunc(motion);//移動函式

    glutMainLoop();

}

旋轉Rotate,滑鼠左鍵按住茶壺可以旋轉它

#include<gl/glut.h>

float mouseX=0,mouseY=0,rotX=0;//滑鼠座標

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);//做清除顏色及深度動作

    glPushMatrix();//備份

        glRotatef(rotX,1,0,0);//旋轉函式(x,y,z)

        glutSolidTeapot(0.3);

    glPopMatrix();//還原

    glutSwapBuffers();

}

void motion(int x,int y)

{

    mouseX=(x-150)/150.0;

    mouseY= -(y-150)/150.0;

    rotX=x;   

    glutPostRedisplay();//貼一張便利貼Post，更新電腦畫面

}

int main(int argc,char ** argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_RGB|GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("04160373_translate rotate scale");

    glutDisplayFunc(display);

    glutMotionFunc(motion);//移動函式

    glutMainLoop();

}
