Implement the 3D view window in a Dialog with OpenCascade
【Preview】
【Motivation】
In my application about simulation on the Real Structure Elements in a construction, the calculation of some parameters is the mainly task which will be solved by the 3D graphic boolean method with Opencascade SDK. However, the white-box test unit should be established before the main module.
First, I think that the visual tools like the a dialog or a window will be helpful to check the boolean arithmetic in my application. Second, a window OCX or light-weight visual tool is mascara for the future.
【Design Item】
A window class “C3DWnd” is designed for disaplaying the Simulated Elements using in the main module. And a instance of the C3DWnd is aggregated in a Dialog class. Based the Idea of the Component, C3DWnd is nested in a DLL module which can be encapsulated as an OCX. On the other hand the “Dialog class” is nested in another module as an “exe file”.
【Code Background】
System: Window XP,sp1;
Compiler: Visual C++ 6.0,sp6;
SDK: Opencascade 5.1;
