Surface Model
 Draft When calculated with the lowest quality setting. Surfaces are divided into very large areas, with the light intensity interpolated between the surface corners. The result is a very fast calculation, at the cost of accuracy. Note: detail objects (like the valve) will still have a large number of surfaces. This is because the calculation engine doesn't try to simplify geometry. |
 Normal The normal quality setting will divide the original geometry into more detailed sections. The result is a fast calculation at the cost of some accuracy. |
 Detailed The highest quality setting will divide the geometry into very small surfaces. Notice that this has revealed a shadow on the back wall, which were practically invisible when using the other detail levels. In other areas like the platform floor, the details provides no additional information. The result is a slow calculation, but with a high level of accuracy. |
 Automatic surface subdivision When using the automatic surface subdivision you might notice that the light flashes on and off for a while before the calculation starts. This is how the calculation engine determines where it needs additional surface details. Notice how the surfaces on the back wall are more detailed to display the shadow. The platform floor is divided like in the normal calculation, because the base configuration was the same (and no more surfaces were needed). The result is a good tradeoff between calculation speed and accuracy. Note: the automatic subdivision uses the detail/draft setting as a base subdivision. |
