What's production quality

However, in practical applications such as movie production, the scenes are
much more complex:
? Thousands of light sources.
? More textures than can ?t in memory.
? More geometry than can ?t in memory (in tessellated form).
? Very complex, programmable shaders for displacement, illumination, and
re?ection. (10,000s lines of code.)
In addition, the images have to be of very high quality:
? High resolution.
? Motion blur.
? Depth of ?eld.
? No spatial or temporal aliasing (no staircase effects, “crawlies”, poppin
etc.)
