摘要: Abstract. Bounding Volume Hierarchy(BVH) organizes geometric objects in the tree based on spatial relationships. Each node in the tree contains an axis-aligned bounding box of all the objects below it. Bounding volume hierarchies are used in many algorithms to support efficient operations on the sets of geometric objects, such as collision detection, ray-tracing, searching of nearest objects, and view frustum culling. The paper focus on the usage of BVH on TopoDS_Shape, and its application. K阅读全文

摘要: Abstract. Starting from OCCT6.8.0 will include one more algorithm for solving global optimization problems. Its development has been triggered by insufficient performance and robustness of existing algorithm of minimization of curve-surface distance in Extrema package. The PSO, Algorithms in this family are stochastic, and this feature can be perceived as opposite to robustness. However, we found it was not only much faster than original deterministic one, but also more robust in complex real-wo阅读全文

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. Key Words. 2d conic intersection, conic equation阅读全文

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. Key Words. 2d line intersection, conic阅读全文

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. Key Words.

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
