This is also dependent on the hardware configuration. Higher face counts will result in more detailed morphology of features but sometimes at the expense of noise or artifacts because of the decimation process. The Input Surface can either be the sparse or dense point cloud (default).įace Count is a measure of the final complexity of the surface. No overhangs or such complex surface features are retained and thus the processing time is usually shorter. The latter results in a simpler surface as the height field is only interpreted as orthogonal to the horizontal plane (X or Y axis).
This surface type is suggested for modeling complex shapes with overhangs and images taken at low oblique angles (i.e. The former retains 3-D pixel information for all points in the input point cloud. Surface Type can either be Arbitary (3-D) or Height field (2.5-D). The parameter options are described below. Generate Meshįrom the Workflow menu, select Build Mesh… to open the dialogue box. In areas of the dense cloud where the points are relatively sparse, the surface can be either interpolated or extrapolated. This process connects the discreet, 3-D pixels in the dense cloud with vector vertices, resulting in a “solid” without any gaps between points. Once the dense point cloud is generated and filtered, the next step is create a continuous 3-D surface of the model.
