Hi all, I''ve coded some simple skeletal animation. It uses multimedia timer. It works at office PIV Win 98 but at home at my old PIII , Win XP machine i have to move the mouse on the glut screen while the animation goes on. Is this because glut does not suppport Win XP? Code is sth like ; void CALLBACK CAnSequence::TimerFunction(UINT wTimerID, UINT msg, DWORD dwUser, DWORD dw1, DWORD dw2) { CAnSequence *seq = (CAnSequence*) dwUser; seq->m_current_frame++; if(seq->m_current_frame >= seq->m_frames) { seq->m_timer->Stop(); } seq->Update(); glutPostRedisplay(); } void animation(void) { seq.Play(); glutIdleFunc(NULL); } void display(void) { glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); seq.m_figure->DisplayDeformed(SOLID); glutSwapBuffers(); } void keyboard(unsigned char key, int x, int y) { if (key == 27) exit(0); if( key == ''r'') { if(xrot == 0) xrot = 4; glutPostRedisplay(); } if( key == ''a'') { glutIdleFunc(animation); } }

I''ll try it. Thank you for replying..
