Study On Three-dimensional Virtual Reality Model About Change Of The Coast Line Of Tianjin

To the ground or coast line a view of three-dimensional digital model and realizes the fleetness travels extensively to show that the technique has been a little bit hot lesson studied in recent years.It of research with developped to promote biggest stereoscopic game, information system and every kind of flights imitate realm technical high speed development.This text to make use of the related technique means to feels for the arithmetic figure image prepares to handle the technique, geography data withdraws the high distance in method, arithmetic figure model establishes and three technical and solid hours in actuality in the three-dimensional conjecture exaggerate to proceeded the thorough research with fast manifestation all.The thesis introduced the lesson an investigative background first with the meaning, combining to introduce to study the linear scope in Tianjin coast line in district with the characteristics;Discuss three the related technique that the conjecture of the three-dimensional realistic models realizes;The next in order the thesis expatiates to establish the theories foundation of the high distance model, and takes to set up to realize three realistic technical system in conjecture in the three-dimensional frame;To the research method that put forward further take into the treatise from an every kind of technique for needing, solve the veins shoot the excellent turning the design with the technical and applied technique in LOD, and studied the conjecture a view hand over to operate with each other of realize way.Finally from three realistic models in the conjecture of the three-dimensional play to show to commence, elaborating on the efficiently solid hour exaggerate three the far and near views of a views fly with the high low altitude, the timespace changes, line frame manifestation, rat the mark hands over to wait the main research function with each other, never together the angle development displays the linear timespace in the coast of Tianjin changes the process, providing the emollient argument to the research contents of the thesis.
