Vector Design Brief
We have 3D a racetrack map that is no longer accurate and needs to be updated. The current map is attached and I have circled the area which is no longer accurate. Unfortunately we do not have the original design files so the whole thing needs to be redone. I have also attached a rough drawing of what the map should look like. It needs to be cleaned up and made into a 3 dimensional piece of art like the attached example of the current map which is not accurate. We need the 3D model made first and then we will need to add in the red, white, and green lines as well as the red circles with numbers which represent the parts of the track where the driver would be either braking or accelerating as well as the gear in which the car will be in.
The final product needs to be delivered as a vector graphic so it can be blown up to poster size.
