Malalkree February 24th, 6. If statements are true that man should apologize and send earned money to that student if whole book was rip off. The 50 page interlude is useful in that it explains why certain setting lead gudie certain results, but you do need to stick with it a bit to get what you are after. This time even complte damning.

It covers all the VRay parameters that we can see after pushing F10 button let me remind, that we are talking about 3ds Max VRay version. All discussed in the book issues are preceded by brief introduction. Then VRay: Global Switches role is clarified with simple discussing all the parameters it is composed of. Every particular issue is illustrated, what makes the learning process very easy.

Author analyzes here aliasing phenomenon and shows the sampling process. Apart from those information, Francesco Legrenzi presents a set of 10 examples to this theme: from very simple, explaining on two renders instance what antialiasing really is - to more complex, clearing up how antialiasing affects textures, bump, DOF, or moire effect.

Some of these includes short tutorial showing how to prepare scenes for discussed problems step-by-step. Again, one brief glance on compared renderings with schematic explanation on it clarifies what this term means. Methods for computing an image such as Radiosity, Ray tracing, Irradiance Map, Light Cache and more are presented and compared with each other.

Then we can get familiar with those, used by VRay. VRay: environment is another discussed parameter, that has huge impact on final image appearance.

Not only because a background texture often makes a huge part of final render or animation space. Again, multitude of illustrations with specified render time and used parameters allows quick learning. What has to be emphasized, topics in the book are presented in a very comprehensive way. At occasion of presenting VRay: Color Mapping tool, we also learn what a light from a physical point of view is, the solar beam is composed of what colors, or even how the process allowing sight unfolds.

Phenomenon of color sight from a biological perspective and some methods for expressing those colors are explained: for example by means of hue, luminosity and saturation, or numerically. With this basics we get to know how computers "perceive" and project colors, and also how to manage the color using software and hardware devices. VRay: Camera is the next rollout in the renderer panel, but the discussion about it starts from 3dsMax camera parameters description, including the focal length, field of view and the others.

Then options from VRay: Camera panel are explained: a set of camera types, field of view term or motion blur phenomenon. The discussion about generating displacement consists of two tools VRay offers.

In this topic the difference between bump and displace is clarified and showed factors which a good quality render with displacement depends on. Due to renderer panel layout, the next issue we are to talk about is VRay: System. Francesco Legrenzi follows the rollout division and presents six groups of parameters separately: Raycaster params, Render region subdivision, Frame stamp, Distributed rendering, VRay log and Miscellaneous options.

These groups differ considerably from themselves. It presents a variety of VRay shaders and maps. These information are exceptionally useful for VRay users, as Vray: Psychical Camera works in similar way to a real one.

Unfortunately nowadays ordinary people tend to forget the focal length, objective luminosity, film sensitivity, or shutter speed terms. It may be caused by progressive simplification of photography, that no more requiers that knowledge from non-professional users.

Here in the book we have all these explained, starting with primitive camera obscura issue. It is said, that light can make or break the image. Starting from describing parameters " All very useful and really worth knowing tools, especially when making a heavy scene, or need hair, whorls of grass or filaments.

In case we want to create a cartoon-like rendering, here is an explanation of VrayToon tool that causes such an effect in post-production. Complicated, but, at the same time, useful, is the topic that explains a composition tricks: necessity in animation, also helpful in still images.

In this part we can get familiar with VRaySphereFade issue. Here we can find three methods of visualizing and saving different channels: via Frame Buffer of 3dsMax, the VFB or the propriety image format. For this reason the last chapter of the book was created. A valuable addition to this research is a brief history of VRay.

As you can see, the book far exceeds the scope of simple explanation of VRay parameters. What makes this book so helpful, is there is no more need to do many, many render tests on your own. Here can be found set of illustrates of some problem gathered in one place. Each one with precisely specified rendering time and applied options.

Topics are discussed very comprehensively: with the explanation of physics, biology, photography laws. The versatility of presented issues, profound analyze of discussed subjects and, above of all, thorough illustration with full-color, makes this publication worth strong recommendation.
