A key issue in modelling is the necessity to add vertices in certain zones of the mesh, and this is often regarded as splitting, or adding, edges in a given region.
Surfaces are actually an extension of NURBS curves but are still a unique object unto themselves. Whereas a curve produces only one-dimensional interpolation, Surfaces have a second extra dimension of interpolation. The first dimension is U, as for curves, and the second dimension is V.
In this article, we will learn how to use textures to give our materials more realism. The biggest problem of working with textures is actually finding or creating a good texture. That's why, its highly recommended that you start as soon as possible to create your own texture library. Textures are mostly image files, which represent certain kinds of surfaces such as wood or stone. They work like wallpaper, which we can place on a surface or object. For instance, if we place an image of wood on a plane, it will give the impression that the plane is made of wood. That's the main principle of using textures. We will make an object look like something in the real world using a texture. For some projects, we may need a special kind of texture, which won't be found in a common library. So we will have to take a picture ourselves, or buy an image from someone. But don't worry, because often we deal with common surfaces that have common textures too.
This tutorial is for those which like to make a realistic water in Blender. It is short tutorial where we show how to control the raymirror and raytransparent.
