3D Visualizations - How Can You Tell Them From Photographs?
For the purposes of this explanation, we categorize 3D visualizations into two types: interior visualizations and exterior visualizations.
~~ Recognizing an Interior Visualization ~~ Any three of the following criteria prove that an image of the interior of a building is a 3D visualization and NOT a photograph: • Lighting not consistent: objects next to each other are illuminated to different degrees • Shadows of objects are entirely missing (!) • Furniture legs cast no shadow on the floor near their feet • Objects (especially people) do not have depth • People have zombie-like expressions • People are all dressed very neatly • People are the same height and no one is overweight (!!) • Plants are identical to the last leaf • Objects are not scaled consistently: some pieces of furniture look out of proportion to others.
Some of the people look out of proportion to one another and out of proportion to the ceiling height or furniture (use this to judge people/'/s heights: door openings are usually seven feet high) ~~ Recognizing an Exterior Visualization ~~ Any three of the following criteria prove that an image of the exterior of a building is a 3D visualization and NOT a photograph: • Trees and plants are repetitive • Lawns look like plastic turf...
no loose leaves, no color or texture variation, no bald spots • Objects next to each other are illuminated to different degrees (as in the case of interior renderings) • People have zombie-like expressions and lack visual depth • People are all dressed very neatly • People are the same height and no one is overweight (!!) • There are not enough people in the scene (populating the scene greatly increases the time a computer takes to create the visualization) • Objects (especially people) are out of proportion (use this to judge people/'/s heights: door openings are usually seven feet high) • Trees in the foreground cast no shadows • People cast no shadows • Shadows of objects are cast in different directions or to in different proportions to their parent objects • There are no blemishes on road asphalt or on sidewalks • There are no loose leaves on the ground near trees • The interiors of buildings are not visible through any windows (if the image is a close-up) • Window panes appear painted If you use the above criteria, you will never again mistake a computer-generated 3D visualization for a photograph!
