呵 長大了- week04

第四周三個程式碼

第一個:使普通茶杯 旋轉

#include <GL/glut.h>

float angle = 0;

void display()

{

    glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );

    glPushMatrix();

        glRotated(angle, 0, 1, 0);

        glutSolidTeapot( 0.3 );

    glPopMatrix();

    glutSwapBuffers();

    angle++;

}

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

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB|GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("week03");

    glutDisplayFunc(display);

    glutIdleFunc(display);

    glutMainLoop();

}

第二個:幫上一個茶杯上燈光

#include <GL/glut.h>

const GLfloat light_ambient[]  = { 0.0f, 0.0f, 0.0f, 1.0f };

const GLfloat light_diffuse[]  = { 1.0f, 1.0f, 1.0f, 1.0f };

const GLfloat light_specular[] = { 1.0f, 1.0f, 1.0f, 1.0f };

const GLfloat light_position[] = { 2.0f, 5.0f, 5.0f, 0.0f };

const GLfloat mat_ambient[]    = { 0.7f, 0.7f, 0.7f, 1.0f };

const GLfloat mat_diffuse[]    = { 0.8f, 0.8f, 0.8f, 1.0f };

const GLfloat mat_specular[]   = { 1.0f, 1.0f, 1.0f, 1.0f };

const GLfloat high_shininess[] = { 100.0f };

void myLight()

{

glEnable(GL_DEPTH_TEST);

    glDepthFunc(GL_LESS);

    glEnable(GL_LIGHT0);

    glEnable(GL_NORMALIZE);

    glEnable(GL_COLOR_MATERIAL);

    glEnable(GL_LIGHTING);

    glLightfv(GL_LIGHT0, GL_AMBIENT,  light_ambient);

    glLightfv(GL_LIGHT0, GL_DIFFUSE,  light_diffuse);

    glLightfv(GL_LIGHT0, GL_SPECULAR, light_specular);

    glLightfv(GL_LIGHT0, GL_POSITION, light_position);

    glMaterialfv(GL_FRONT, GL_AMBIENT,   mat_ambient);

    glMaterialfv(GL_FRONT, GL_DIFFUSE,   mat_diffuse);

    glMaterialfv(GL_FRONT, GL_SPECULAR,  mat_specular);

    glMaterialfv(GL_FRONT, GL_SHININESS, high_shininess);

}

float angle = 0;

void display()

{

    glClearColor(1,1,1,1);

    glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );

    glPushMatrix();

        glRotated(angle, 0, 1, 0);

        glColor3f(1,1,0);

        glutSolidTeapot( 0.3 );

    glPopMatrix();

    glutSwapBuffers();

    angle++;

}

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

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB|GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("week04");

    glutDisplayFunc(display);

    glutIdleFunc(display);

    myLight();

    glutMainLoop();

}

第三個:兩個杯子 選轉移動交換順序 觀察變化(公轉跟自轉)

#include <GL/glut.h>
float angle = 0;
void display()
{
    glEnable(GL_DEPTH_TEST);
    glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );
    glPushMatrix();
        glTranslatef(0.6,0,0);
        glRotated(angle, 0, 1, 0);
        glColor3f(1,1,0);
        glutSolidTeapot(0.3);
    glPopMatrix();
    glPushMatrix();
        glRotated(angle, 0, 1, 0);
        glTranslatef(0.6,0,0);
        glColor3f(1,0,0);
        glutSolidTeapot(0.3);
    glPopMatrix();
    glutSwapBuffers();
    angle++;
}
int main(int argc, char* argv[] )
{
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_RGB|GLUT_DOUBLE|GLUT_DEPTH);
    glutCreateWindow("week04");
    glutDisplayFunc(display);
    glutIdleFunc(display);
    glutMainLoop();
}
