By default, ContextCapture generates a 3D model with a resolution automatically adapted to the resolution of the input photographs. However, some applications may require to control the output resolution more tightly. The resolution limit setting allows to clamp the resolution of the output 3D model to a user-specified limit in meters (or in units for non-georeferenced reconstructions). If the resolution of the input photos is finer than the limit in some areas, the 3D model will be generated with a resolution equal to the specified limit in these areas. By default, the resolution limit is set to zero, so that the resolution is never clamped.
