Hi all! Im working on a small 3d tennis game, but im not good with math. Can anyone make me algorithm for tennis ball movement (simulation). I have this parameters: ball starting point (x=left/right,y=up/down, z=is forward/backward), ball ending/bounce point which y is always 0. y at (z=0) should be 40, spin parameter which is basically here just to make ball goes over net in different situations. So basically i need to calculate parabola. thanks!
