Independently, a geographical study of the convergence and the moving toward interstate was utilized to make an exact scale "universe" of the mishap scene in the PC. A three-dimensional scale model of the specific large apparatus engaged with the mishap was implicit the PC and delivered photorealistic utilizing photos of the mishap vehicle. A three-dimensional "mist program" was then used to produce a similar thickness of mist as estimated by the exploring officials and confirmed by the mishap time photos. The drivers-eye HD-video was "cameramarched" outline by-outline with the PC universe of the mishap scene utilizing a program which photogrammetrically tracks many milestone highlights showing up in the video.
