“The gamut of possible images derived from a model is constrained by what is physically possibly. Conversely, the digital image has no constraints, which requires proportionate extra care, effort, and art direction to ensure the images rendered look realistic from all angles. A model provides interactive lighting, atmospheric effects, radiosity, organic textures, and complexity of shape for free, by virtue of existing in the real world.” — Lorne Peterson
