China is one of the largest countries today. With over a population of 1 billion people, and with the third largest landmass in the entire world, there is no doubt that the Chinese has left footprints of many cultural and historical events, stories, and images. The earliest historical records of China can be found as early as 1,200 BC — from the earliest Chinese society, the Shang Dynasty. From then on, a lot of societal changes has happened, as well as cultural changes which paved the way for the modern China we see today. With such a rich cultural history the Chinese have, it is safe to say that the cultural reminders that are left should be kept and should be preserved for the future generations to see. With that, the use of technology could …show more content…
The Longmen Grottoes is located at Luoyang, Henan Province in China. The Longmen Grottoes have more than 2,300 caves and niches carved into limestone cliffs that are almost 1 km long. The caves in them have around 110,000 Buddhist stone statues, 60 stupas and 2,800 inscriptions. Furthermore, the reason why the Longmen Grottoes was made was because during the period of its creation, Luoyang was the capital of the Northern Wei Dynasty until the early Tang Dynasty which is over a 150 year period. This can be said as the different caves have different styles of carving, as the older sculptures show characteristics of a “Central China Style”. While the later statues show the Characteristics of the “Great Tang Style”. In order to preserve such great sculptures from deterioration, a technique called “3D Digitalization” is being used. 3D Digitalization is basically a way for people to have a 3D render of an object. It might sound easy, but it will take time to produce high quality 3D models and accurate ones. The steps include 3D data capturing, 3D registration, geometric modelling and texture …show more content…
Time of flight scanners are cameras which calculate the distance between the object and the camera — lasers or a light pulse is used by the camera in order to detect the distance. This will be performed at almost every angle of the object, with triangulation, the data will be more precise as all of the data that are gathered will be used in order to form the 3D render. The second step is 3D registration. This step is needed to fix the errors which the cameras may have committed. As lasers and pulses are used at many different points, alignment is needed to position the points properly so that the model will show the original object accurately. For the third step, geometric modelling, it is the way for people to lessen the data used by the 3D modelling software without decreasing its quality. This will make connecting the mesh clouds easier as they would be easily identifiable, then connected, to form the object in which we need to make. This is an important step because we use polygons which gives us an easier time to connect them. The last step, texture mapping, is basically giving the 3D model the texture it has in real life. For this to happen, very high quality pictures of the surface must be obtained from many angles. The pictures are then transferred and wrapped around the 3D model giving it the texture it has in real life. If the steps are done correctly, an accurate 3D model is reproduced. The
