Siemens PLM Software releases Version 51.0 of D-Cubed CDM


D-Cubed CDM (Collision Detection Manager) enhancements include:


Closest Approach Performance Improvements between Point Clouds and Parts

This release contains significant improvements to the performance of closest approach computations between large numbers of points, including point clouds, and an accurate part. A new CDM interface function has been introduced that greatly simplifies the implementation of application functionality in this area. The computations support single and double precision data, minimize the use of memory, and the computations can be multithreaded. No sorting of the input positions of the points is required.


Performance Improvements on Faceted Models

A CDM strength is its ability to perform computations involving accurate and faceted models. Good performance requires fast algorithms for both classes of geometry. This release has significant improvements to performance on models with surfaces that contain large numbers of facets. This is achieved by developments in the area of the facet boxing hierarchy. The improvements benefit faceted models, and models containing a mixture of accurate and faceted geometry.


Custom Memory Allocation

This release extends custom memory allocation to all supported platforms.


Collisions and Closest Approach on Tolerant Data

Tolerant data can occur when a model is translated from one CAD format to another. Some elements of the model may be locally much less accurate than is typical of solid model data. These regions of the model can require special treatment for various operations, including collision and clearance computations. The substantive incremental improvements to the handling of tolerant data are continued in this release.


About D-Cubed CDM

D-Cubed Collision Detection Manager (CDM) is a software component that offers collision detection and clearance distance measurement for solid, surface and wireframe models. It supports accurate, tolerant and faceted geometry. Used in assembly, mechanism, machining and measurement simulation environments, CDM offers a range of algorithms to interactively detect collisions and compute clearances, even on large, complex assemblies. Performance is particularly excellent for repeated computations on models that are in motion. CDM is compatible with most applications, being independent of any particular modeler or model format.
