課堂作業(一)

Shape 參數用法:



Loop //迴圈

fan //扇形





quad //四邊形

polygon //多邊形






課堂作業(二)

程式碼:
#include<GL/glut.h>
void display()
{
    glBegin(GL_POLYGON);
        glColor3ub(174,238,238);
        glVertex3f(0,0,0);
        glVertex3f(1,1,0);
        glVertex3f(0,-1,0);
    glEnd();
    glutSwapBuffers();
}
int main(int argc,char**argv)
{
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
    glutCreateWindow("hi");
    glutDisplayFunc(display);
    glutMainLoop();
}



課堂作業(三)

小畫家查詢Color 座標方法



課堂作業(四)

程式碼:
#include<GL/glut.h>
#include<stdio.h>
void mouse(int button, int state, int x, int y)
{
    if(state==GLUT_DOWN)
        printf("glVertex3f((%d-150)/150.0,-(%d-150)/150.0,0.0);\n",x,y);  //用mouse找出座標位置
}
void display()
{
    glClear(GL_COLOR_BUFFER_BIT);
    glClearColor(230/255.0,243/255.0,211/255.0,0.5);
