week10

1.期中考:OpenGL必背10函式

2.複習:移動,旋轉,縮放

3.主題:T-R-T 旋轉(改變旋轉軸)

4.主題:glut

5.#include <GL/glut.h>
float angle=0;
void display()
{
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    glPushMatrix();
        glTranslatef(0,0.5,0);
        glutSolidTeapot(0.3);
    glPopMatrix();
    glPushMatrix();

    glPopMatrix();

    glPushMatrix();
        glTranslatef(0.50,0.625,0);
        glRotatef(angle,0,0,1);
        glTranslatef(0.6,0,0);

        glRotatef(-90,0,1,0);
        glutSolidCone(0.2,0.6,30,30);
    glPopMatrix();
    glutSwapBuffers();
}
void motion(int x, int y)
{
    angle=x;
    display();
}
int main(int argc, char**argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("06160396-week10");

    glutDisplayFunc(display);

    glutIdleFunc(display);

    glutMainLoop();

}
