Surface Super Capping
The Super Capping command enables you to generate High Quality capping surfaces by adhering to a set of input constraints. These constraints provide the reference for the shape of the surface. During the surface generation, high priority is given to get Class A surfaces which preserve the mood of the input data and at the same time satisfy the input constraints as much as possible.
Being a reverse engineering tool, the source of input for constraints is usually a mesh data or point cloud data over which the surface is to be generated. Additionally, it is also possible to fill islands or holes present in an existing surface, or to create surfaces through curves. An example would be covering a wireframe structure with surfaces.
The Constraint drop-down list in the selection list is used to specify the type of input data to be used for the surface generation. Using the available options, you can specify boundary constraints (that define the boundary shape of the surface) and internal constraints (that define the form of the surface). Depending on selection made for Constraint, more options will be available in the selection list to provide input for the source data.
It is possible to define the inherent form of the surface by making the required selection from the Generic Shape drop-down list under More Options. The Bezier surface and Saddle curvature are among the various possible selections you can make to define the generic shape.
Optionally, you can select the Smart Domain check box to define the surface domain that will complement the form of the generic shape.
The use of No. of Steps is recommended when the progressive approach is applied to reach the result. It takes longer time but generally provides a higher quality results.
While generating the surface it is not always practical to fully satisfy all the requested constraints as it might result in waviness in the surface (for example, in cases where excess noise is present in the point cloud data). In such a case, it is necessary to provide a tolerance value greater than the noise to get a smooth surface. The various tolerance values can be specified in the Precision dialog box displayed by selecting the Precision option in the selection list.
The surface generated by Super Capping is not bounded to have a limited number of edges. Hence, once you have identified a mesh-area that should be covered by a single surface, there is no need to be concerned about the number of edges the surface will generate.
The other HQ Reverse Engineering commands help you in analyzing and preprocessing the source data to be used for Super Capping.
