Computer grapic marble surface.

Subsurface scattering is important for realistic 3d computer graphics being necessary for the rendering of materials such as marble skin leaves wax and milk. In computer graphics the application of a type of surface to a 3d image. Point clouds are also sometimes used as temporary ways to represent an object with the goal of using the points to create one or more of the three permanent representations. Dedicated graphics is what propels the surface book 3 into performance territory for us and makes it the most powerful surface on the market today.

A texture can be uniform such as a brick wall or irregular such as wood grain or marble. Its high resolution 28 inch display 4 500 x 3 000 is touch sensitive which means it can be used as a giant graphics tablet when you lay it down flat using the hinge at the back. The common method is to create a 2d bitmapped image of the texture called a texture map which is then wrapped around the 3d object. Starting from a computer model it might be possible to segment the statue surface according to the chisels used to carve each region figure 2.

In addition to capturing shape we also wanted to capture color. Anything with a screen needs some kind of graphics processor whether it be a desktop laptop or even. We demonstrate the approach with models of granite and marble statues as well as a sandstone column. While your computer s cpu and ram are also important the gpu is usually the most critical component when it comes to playing pc games.

Microsoft s surface studio 2 is an all in one that can do a few things the imac cannot. In technical applications of 3d computer graphics such as computer aided design and computer aided manufacturing surfaces are one way of representing objects. The other ways are wireframe lines and curves and solids. More specifically we wanted to compute the surface reflectance of each point on the statues we scanned.

If you don t have a powerful enough gpu you can t play newer pc games or you may have to play them with lower. All of the images you see on your screen are produced by the video card in your computer. If subsurface scattering is not implemented the material may look unnatural like plastic or metal. The composition of minerals near the surface we simulate the scat tering of light inside the stone using a general subsurface monte carlo ray tracer.

These techniques can capture many aspects of the time dependent appearance of stone. The card contains the graphics processing unit or gpu which is a parallel processor designed for producing images.
