GLUT Project
打入程式碼
#include <GL/glut.h>
float rotX=0;
void display()
{
glClearColor(0,0,1,1);
glClear(GL_COLOR_BUFFER_BIT);
glPushMatrix();
glRotatef(rotX, 0,1,0);
glColor3f(1,1,0);
glutSolidTeapot(0.3);
glPopMatrix();
glutSwapBuffers();
}
void motion(int x, int y)
{
rotX=x;
display();
}
int main(int argc, char**argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("hello3D");
glutDisplayFunc(display);
glutMotionFunc(motion);
glutMainLoop();
}
