I checked the tutorial it uses the mesh box extent. As i said, i only have a point and moving vector of a ball.

RE: Trail to point
you can use what you would like for the update, you dont need to call mesh box extent.

as you can see there void update(C Vec &new_pos_start, C Vec &new_pos_end)

all you need is to call new pos start and new pos end to have your trail set up

Thanks. I want the trail to originate from the ball center and then spread at the end. Now i can set the start and end point but then i am not able to set the width at the start and end ?

Do you get i what i am saying ??

well you can define the width, and take last moving vector + new moving vector to get your direction, and you can set up from pos + width depending of direction.
