To make rendered graphics look more realistic, Direct3D provides the ability to draw textures on object surfaces. Generally speaking, a texture is a two-dimensional picture or pictures of an object's surface. It is also called a texture. Textures can make objects look more realistic when they are mapped to the surface in a specific way. In the current popular graphics system, texture rendering has become an essential rendering method. Textured paper stickers can be understood as the color of pixels applied to the surface of an object. In the real world, textures represent the colors, patterns, and tactile features of an object. But in Direct3D, texture only represents the color pattern on the surface of the object, it cannot change the geometry of the object. Further, it is simply a highly computationally intensive activity.
