a newbie question

i am making a game and this is my first time however when i move my object in the game especially the left and right turns somehow the whole screen seems to jerk a bit i wonder is there anyway to stop the jerking?

secondly i would like to find out about these 2 function

void glutKeyboardUpFunc(void (*func)(unsigned char key,int x,int y));
void glutSpecialUpFunc(void (*func)(int key,int x, int y));

however i am new to opengl hence i donno where to read up these however i am assign to find out more about this hence can someone help me?

hey avalanch3, i’m not sure how to answer the first question. by jerky, do you mean frame rate dependent behavior?

as for the glut functions, you can read about them here:
