Important Materials Theory - Photographic Rendering with V-Ray for SketchUp - page 263

Summary
We have seen that without light, we have no color as the wavelengths contained in
white light and their subsequent absorption and reflection from the surface of objects
in the real world is the mechanism that brings color to the world around us.
We also noted the importance of the RGB color model as regards color reproduction
given that trying to recreate the entire light spectrum inside both hardware and soft-
ware applications would be problematic and costly to say the least.
And very importantly, we considered some of the typical behaviors seen in real-world
surfaces that need to be recreated inside our V-Ray Materials, including:
• The use of realistic color values to create believable reflectance
• Reflectivity and the scattering of light to produce blurred reflections
• Transmissive effects, such as refraction, SSS, and translucency
• Finally, the importance of energy conservation in materials so that they be-
have in a physically accurate manner, thus enhancing their photographic qual-
ity
In Chapter 8 , Composition and Cameras , we will return to the subjects of composition
and camera setup so that we can better understand how issues such as shot type ,
aspect ratios , output resolution , and focal length can all massively affect the quality of
any final renders we create.
