I know that in blender you can use blueprints to model any vehicle but I couldn't found any blueprints for this bus VDL Jonkheere Mistral 30 from the Jutc company and I would love to start a project for it. I also tried writing a letter to the manufacturers asking permission for blueprints and didn't get a response. However I do have alot of images of the bus as I am from Jamaica but I'm not sure if the images needs to be flat like how a typical blueprint would look like (Front view, side view etc). I need professional advice thanks.
If you have access to a bus that is parked and you can do the photographs yourself it would be a lot easier. Just go around the bus making a lot of photos with the same lens, import the images into the video clip editor and then use motion tracking as an aid to re-construct the object.
You don't need a fancy camera. A phone will be good enough. If you are concerned about the distortion of the lens, Blender has tools to undistort the image.
