1.上周進度:MOVE移動

    

    TODO:到jsyeh.org/3dcg10

    下載windows.zip

            data.zip

            glut32.dll

     

2.主題:移動、旋轉、縮放

   

#include <GL/glut.h>

float angle=0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT);

    glPushMatrix();

        glRotatef(angle, 0,0,1);

        glutSolidTeapot(0.3);

    glPopMatrix();

    glutSwapBuffers();

    angle++;

}

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

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week04 transformation");

    glutIdleFunc(display);

    glutDisplayFunc(display);

    glutMainLoop();

}

用滑鼠手動旋轉

#include <GL/glut.h>

float angle=0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT);

    glPushMatrix();

        glRotatef(angle, 0,0,1);

        glutSolidTeapot(0.3);

    glPopMatrix();

    glutSwapBuffers();

    ///angle++;

}

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

{

}

void motion(int x, int y)

{

    angle=x;

    glutPostRedisplay();

}

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

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week04 transformation");

    glutMouseFunc(mouse);

    glutMotionFunc(motion);

    ///glutIdleFunc(display);

    glutDisplayFunc(display);

    glutMainLoop();

}

左鍵旋轉,右鍵移動

#include <stdio.h>

#include <GL/glut.h>

float angle=0, teapotX=0, teapotY=0;

int oldX=0, oldY=0, nowRotate=0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glTranslatef(teapotX,teapotY,0);

        glRotatef(angle,0,0,1);

        glutSolidTeapot(0.3);

    glPopMatrix();

    glutSwapBuffers();

    ///angle++;

}

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

{

    if(button==GLUT_LEFT_BUTTON && state==GLUT_DOWN) nowRotate=1;

    if(button==GLUT_RIGHT_BUTTON && state==GLUT_DOWN) nowRotate=0;

    oldX=x; oldY=y;

}

void motion(int x, int y)

{

    if(nowRotate==1) angle += (x-oldX);

    else {

        teapotX += (x-oldX)/150.0;

        teapotY += (oldY-y)/150.0;

    }

    oldX=x; oldY=y;

    glutPostRedisplay();

}

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

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week04 transformation");

    glutMouseFunc(mouse);

    glutMotionFunc(motion);

    ///glutIdleFunc(display);

    glutDisplayFunc(display);

    glutMainLoop();

}

3.範例:Transformation.exe

4.期中考題

   

week03

1.親手寫GLUT範例

#include <GL/glut.h>
void display()
{
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    glutSolidTeapot(0.3);

    glutSwapBuffers();
}

int main(int argc, char**argv)
{
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
    glutCreateWindow("Week03 mouse操作");

    glutDisplayFunc(display);


    glutMainLoop();
}

2.色彩+滑鼠

#include <GL/glut.h>

void display()

{

    glClearColor(1,1,0,1);

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glColor3f(0,1,0);

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}

#include <stdio.h>

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

{

    if(state==GLUT_DOWN) printf("glVertex2f(%f, %f);\n",(x-150)/150.0,-(y-150)/150.0);

}

int main(int argc, char**argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("Week03 mouse操作");

    glutDisplayFunc(display);

    glutMouseFunc(mouse);

    glutMainLoop();

}

3.移動+顯示座標

#include <GL/glut.h>
float teapotX=0, teapotY=0;
void display()
{
    glClearColor(1,1,0,1);
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    glColor3f(0,1,0);
    glPushMatrix();
        glTranslatef(teapotX, teapotY, 0);
        glutSolidTeapot(0.3);
    glPopMatrix();
    glutSwapBuffers();
}
#include <stdio.h>
void mouse(int button, int state, int x, int y)
{
    if(state==GLUT_DOWN) printf("glVertex2f(%f, %f);\n",(x-150)/150.0,-(y-150)/150.0);
}
void motion(int x, int y)
{
    teapotX=(x-150)/150.0; teapotY= -(y-150)/150.0;
    printf("%d %d\n", x, y);
    glutPostRedisplay();
}
int main(int argc, char**argv)
{
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
    glutCreateWindow("Week03 mouse操作");

    glutDisplayFunc(display);
    glutMouseFunc(mouse);
    glutMotionFunc(motion);
    glutMainLoop();
}

week02

1.TODO: jsyeh.org/3dcg10

    

   下載 data, win32, glut32.dll

2.執行Shape.exe

3.將data放入之後

   執行Transformation.exe

4.利用兩個程式 組成新的圖案

#include <GL/glut.h>

void display()

{

    glClear(GL_COLOR_BUFFER_BIT);

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}

int main(int argc, char**argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE);

    glutCreateWindow("02163610_Week02 Good!!!");

    glutDisplayFunc(display);

    glutMainLoop();

}

5.動手打一次程式碼

#include <GL/glut.h>

void display()

{

    glClear(GL_COLOR_BUFFER_BIT);

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}

int main(int argc, char**argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE);

    glutCreateWindow("02163610_Week02 Good!!!");

    glutDisplayFunc(display);

    glutMainLoop();

}

調顏色

#include <GL/glut.h>

void display()

{

    glClear(GL_COLOR_BUFFER_BIT);

    glColor3f(1,1,0);///黃色

    glBegin(GL_POLYGON);

        glColor3f(1.0f, 0.0f, 0.0f);   glVertex2f(0.0f,   1.0f);

        glColor3f(0.0f, 1.0f, 0.0f);   glVertex2f(0.87f,  -0.5f);

        glColor3f(0.0f, 0.0f, 1.0f);   glVertex2f(-0.1f, -0.5f);

    glEnd();

    glutSwapBuffers();

}

int main(int argc, char**argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE);

    glutCreateWindow("02163610_Week02 Good!!!");

    glutDisplayFunc(display);

    glutMainLoop();

}
