劃出藍色方塊
程式碼:
#include <GL/glut.h>
#include <stdio.h>
float vx[2000],vy[2000];
float angle=0;
int N=0;
void display( )
{
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
glPushMatrix( ); ///備份矩陣
glRotatef(angle,0,0,1); ///旋轉
glScalef(0.5,0.1,0.1);
glColor3f(0.3,0.3,1.0); ///顏色為藍色
glutSolidCube(1); ///方塊
glPopMatrix( ); ///還原矩陣
glutSwapBuffers( );
}
void mouse(int button,int state,int x,int y) ///不做事
{
}
void motion(int x,int y)
{
printf("%d %d\n",x,y);
vx[N]=(x-150)/150.0;
vy[N]=-(y-150)/150.0;
N++;
display( );
}

方塊"自行"旋轉
