StripTopol Sample Description

StripTopol Sample

Source code for StripTopol sample is available in Samples\VC folder of the installation directory. If you are going to compile the project we suggest to copy whole VC directory to location outside of the installation folder. StripTopol is a simple MFC dialog-based application, which demonstrates topological operations performed programmatically on strips of surface patches. 

See also Visual C++ Samples, All samples

Running the application

On load the application displays the default model (cube). For simplicity the application displays and modifies information related to the first top level object in the model (see Structure of DInsight models). Controls on the right display properties of the surface strip in the object. "Joint" edit boxes allow modification of the current joint. In case of Generic 3D Section the modification will be applied at the current z position, which is in the middle by default.

The menu contains topological commands which modify structure of the surface strip. It is important to remember that edges are numbered in CCW direction when looking from the end of the local Z axis. This can be verified by changing coordinate in "Joint" edit boxes. Number of a surface patch is the number of its first edge in the same direction.

New Knot command allows increasing number of knots in the axial base, hence increasing degree of freedom for modifications along z axis. Note that this command has no meaning for Surface Of Revolution objets as those do not have axial base.

File submenu allows saving and loading models.
