The Face property specifies a 2D picture on the face of the cube. Cube map texturing is a form of texture mapping that uses a 3D direction vector to index into a texture that is six 2D textures arranged like the faces of a cube. Again consider the environment around you now. You can "capture" a 360 degree view of your surroundings by standing in one place and taking six photographs each at an orthogonal 90 degree view from the others. The rendering method of the environment texture is an image ordered method (we scan pixels by final image scanlines) than imply that high resolution textures are rendered nearly as fast as low resolution textures. The rendering speed increase as final image resolution increase. The Index property specifies the index of the face.

Below is a set of six such images that capture an indoor environment ( in our case a car ):

The following properties can be used to access any face of the cube:

• The Face(exFrontFace) or FrontFace property returns the face on the front.
• The Face(exBottomFace) or BottomFace property returns the face on the bottom.
• The Face(exRightFace) or RightFace property returns the face on the right.
• The Face(exLeftFace) or LeftFace property returns the face on the front.
• The Face(exTopFace) or TopFace property returns the top face.
• The Face(exDownFace) or DownFace property returns down face.
