Clip C++ Sample

Clip C++ Sample

Source code for Clip sample is available in Samples\VC folder of the installation directory.

Clip is a simple application, which demonstrates programming of Clipping Planes.

The application

Implementation

All KernelCAD related code is contained in the ClipDlg class. Location and orientation of the plane are controlled via IAxis interface queried form ISection of the Cone.

The only non-trivial part is the implementation of sharing. It is implemented in ClipDlg::OnCheckShare().handler. Call to IClipPlane::Share makes the plane global and available for use by any other object in the model. IClipPlane::UseShared called for clipping planes of both Cylinder and Box objects force the shared plane to be used as the first plane of the objects.
