課堂1
point
glColor3f控制顏色 滑鼠上下拉可改變顏色
glVertex2f控制點的位置 滑鼠上下拉可移動位置






課堂2
三角形
#include <GL/glut.h>
void display()
{
    glBegin(GL_POLYGON);
    glColor3f(0,0,1);
    glVertex3f(-1.0,0.0,0.0);
    glColor3f(1,0,0);
    glVertex3f(1.00,1.0,0.0);
    glColor3f(0,1,0);
    glVertex3f(1.0,-1.0,0.0);
    glEnd();
    glutSwapBuffers();


}
int main(int argc, char**argv)
{
    glutInit(&argc,argv);
    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
    glutCreateWindow("hello3D");
    glutDisplayFunc(display);
    glutMainLoop();
}

課堂3
#include <GL/glut.h>
void display()
{
    glClearColor(144/255.0,168/255.0,56/255.0,1);
    glClear(GL_COLOR_BUFFER_BIT);
    glBegin(GL_POLYGON);
    glColor3f(192/255.0,215/255.0,107/255.0);
    glVertex3f((95-100)/100.0,-(49-100)/100.0,0);
    glVertex3f((17-100)/100.0,-(106-100)/100.0,0.0);
    glVertex3f((93-100)/100.0,-(165-100)/100.0,0.0);
    glVertex3f((174-100)/100.0,-(103-100)/100.0,0.0);
    glEnd();
    glutSwapBuffers();


}
int main(int argc, char**argv)
{
    glutInit(&argc,argv);
    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
    glutCreateWindow("hello3D");
    glutDisplayFunc(display);
    glutMainLoop();
}

課堂4 用滑鼠點座標印出程式

#include <GL/glut.h>

#include <stdio.h>

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

{

    if(state==GLUT_DOWN)

        printf("        glVertex3f((%d-100)/100.0,-(%d-100)/100.0,0)\n;",x,y);

}

void display()

{

    glClearColor(144/255.0,168/255.0,56/255.0,1);

    glClear(GL_COLOR_BUFFER_BIT);

    glBegin(GL_POLYGON);

    glColor3ub(192,215,107);

    glVertex3f((95-100)/100.0,-(49-100)/100.0,0);

    glVertex3f((17-100)/100.0,-(106-100)/100.0,0.0);

    glVertex3f((93-100)/100.0,-(165-100)/100.0,0.0);

    glVertex3f((174-100)/100.0,-(103-100)/100.0,0.0);

    glEnd();

    glutSwapBuffers();

}

int main(int argc, char**argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("hello3D");

    glutDisplayFunc(display);

    glutMouseFunc(mouse);

    glutMainLoop();

}
