摘要: Abstract. OpenCASCADE provides the algorithm to implement of the intersection between two 2d conic curve. The conic is defined by its implicit quadaratic equation, so the intersection problem is become a polynomial roots finding problem. The paper focus on the two conic curve intersection algorithm implementation.

摘要: Abstract. OpenCASCADE provides the algorithm to implementation of the analytical intersection between a 2d line and another conic curve. The conic is defined by its implicit quadaratic equation, so the intersection problem is become a polynomial roots finding problem. The paper focus on the 2d line intersection another conic algorithm implementation.

摘要: Abstract. OpenCASCADE geometric tools provide algorithms to calculate the intersection of two 2d curves, surfaces, or a 3d curve and a surface. Those are the basis of the Boolean Operation, so under the implementation can help to under the BO algorithms. The paper focus on the intersection of two 2d analytical line.

摘要: In Visual Studio you can specify changes to environment variables in the project settings. Open your project, go to Project -> Properties... Under Configuration Properties -> Debugging, edit the Environment value to set environment variables.
For example, if you want to add the directory “c:\foo\bin” to the path when debugging your application, set the Environment value to “PATH=%PATH%;c:\foo\bin”.阅读全文

摘要: Abstract. OpenCASCADE7.1.0 introduces new built-in interactive object AIS_Manipulator providing interface for moving objects within 3D viewer. The class features three kinds of transformation modes for attached objects: translation through axis, scaling within axis, rotation around axis. The object can be activated using vmanipulator command within Draw Test Harness.

摘要: Abstract. Qt’s ActiveX and COM support allows Qt for Windows developers to access and use ActiveX controls and COM objects provided by any ActiveX server in their Qt applications. Make their Qt application available as COM servers, with any number of Qt objects and widgets as COM objects and ActiveX controls. Make OpenSceneGraph to ActiveX controls then you can use it in other place, like IE.
