SynopsisThis book details the aesthetics of rendering with mental ray. It describes the varieties of shader programming from the point of view of increasing perceptual complexity: from color to the output of the final image., An increasing number of artists and programmers in visual effects and broadcast production now use mental ray, a high performance rendering engine for generating photorealistic images. This book details the aesthetics of rendering with mental ray. It describes the varieties of shader programming from the point of view of increasing perceptual complexity: from color, to the effects of light, to the manipulation of shape, to the output of the final image. It includes many example shaders, including the simplest shader possible in each category that can serve as a starting point for further customization. These examples will also provide a basis for training artists interested in extending their technical skills by learning how the write shaders for mental ray., The word "render" isn't unique to the vocabulary of computer graphics. We can talk about a "watercolor rendering," a "musical rendering" or a "poetic rendering." In each of these, there is a transformation from one domain to another: from the landscape before the painter to color on paper, from musical notation to sound, from the associations in a poet's mind to a book of poetry. Figure 1.1: Czar's Waiting Room, Main Railway Station, Helsinki, Eliel Saarinen, 1910, watercolor. But the type of rendering that may come closest to what we mean when we talk about rendering in computer graphics is in architecture. Geometric blueprints and technical specifications of building materials are transformed in the architectural rendering into a picture of the building 1 Introduction as it will appear when construction is complete. In addition to the designs of the building's geometry and its visual characteristics, the artist chooses a point of view to depict the scene in perspective. This is a transformation of a description of imagined space into a picture of that space. In a watercolor by architect Eliel Saarinen (Figure 1.1), the effect of light on marble is demonstrated in a way that would be lost in even a careful reading of blueprints and descriptions of materials. A mere brushstroke of a particular color in a particular place paradoxically transforms the dull matte appearance of watercolor into the sheen of polished stone.
