快暴斃-期末總複習

做出有顏色的茶壺

 一開始先做出平凡無色的茶壺

#include <GL/glut.h>

void display(){

     glClearColor( 0,1,1,0);  ///用來ClearColor (紅,綠,藍,黑)設定BACKGROUND

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

        //(等等要幫茶壺增添色彩！！！)

        glutSolidTeapot( 0.3 );

    glutSwapBuffers();

}

int main( int argc, char ** argv )

{

    glutInit( &argc, argv);

    glutInitWindowSize(400,400);  //將視窗放大

    glutInitWindowPosition(600,200);   //視窗的位置

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("08160465");

    glutDisplayFunc(display);

    glutMainLoop();

}

增加glColor3f( 1,0,1 );  幫茶壺上色

#include <GL/glut.h>

void display(){

     glClearColor( 0,1,1,0);  ///用來ClearColor (紅,綠,藍,黑)設定BACKGROUND

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

        glColor3f( 1,0,1 );  //茶壺上色

        glutSolidTeapot( 0.3 );

    glutSwapBuffers();

}

int main( int argc, char ** argv )

{

    glutInit( &argc, argv);

    glutInitWindowSize(400,400);  //將視窗放大

    glutInitWindowPosition(600,200);   //視窗的位置

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("08160465");

    glutDisplayFunc(display);

    glutMainLoop();

}

進階

加入光影程式

#include <GL/glut.h>

void display(){

    glClearColor( 0,1,0,0);  ///用來ClearColor (紅,綠,藍,黑)設定BACKGROUND

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

        glColor3f( 1,1,0 );   //茶壺上色 換個鮮豔的黃色！！！

        glutSolidTeapot( 0.3 );

    glutSwapBuffers();

}
