What unit should I choose for 1 [m], what value is the best? For example I have a football mesh. In reality the radius of the ball is about 11 cm (0,11m). Here on the screen:
the radius is 0,70 (I have float variable in which I store 0.70f). So this makes that in my game 0,70 [unit] means 0.11 [m], so 1 [m] is in fact 6,3636 units in my game.
I would like to scale my mesh and choose the scale of the world that 1 [m] = 1 [unit]. Without this there are some issues with physic. So from physic engine and generally logical point of view it would be the best to choose 1[m] as 1[unit], so radius float 0.11f means 0.11 [m]. However You know floats numbers have inacurracies, so is it good to choose 1[m] as 1[unit] or maybe better choice would be 1[m] as 100[unit]??? What is the best scale of the game environment?
