The key feature of the primitive arrays is that the primitive data is not duplicated. For example, two polygons could share the same vertices, so it is more efficient to keep the vertices in a single array and specify the polygon vertices with indices of this array. In addition to such kind of memory savings, the OpenGl graphics driver provides the Vertex Buffer Objects (VBO). VBO is a sort of video memory storage that can be allocated to hold the primitive arrays, thus making the display operations more efficient and releasing the RAM memory. - -The Vertex Buffer Objects are enabled by default, but VBOs availability depends on the implementation of OpenGl. If the VBOs are unavailable or there is not enough video memory to store the primitive arrays, the RAM memory will be used to store the arrays. - -The Vertex Buffer Objects can be disabled at the application level.

It provides flexible means of displaying meshes along with associated pre- and post-processor data. From a developer's point of view, it is easy to integrate the *MeshVS* component into any mesh-related application with the following guidelines: * Derive a data source class from the *MeshVS_DataSource* class. -* Re-implement its virtual methods, so as to give the MeshVS component access to the application data model. This is the most important part of the job, since visualization performance is affected by performance of data retrieval methods of your data source class. -* Create an instance of MeshVS_Mesh class. -* Create an instance of your data source class and pass it to a MeshVS_Mesh object through the SetDataSource() method. -* Create one or several objects of MeshVS_PrsBuilder-derived classes (standard, included in the MeshVS package, or your custom ones). -* Each PrsBuilder is responsible for drawing a MeshVS_Mesh presentation in a certain display mode(s) specified as a PrsBuilder constructor's argument. Display mode is treated by MeshVS classes as a combination of bit flags (two least significant bits are used to encode standard display modes: wireframe, shading and shrink). -* Pass these objects to the MeshVS_Mesh::AddBuilder() method. MeshVS_Mesh takes advantage of improved selection highlighting mechanism: it highlights its selected entities itself, with the help of so called "highlighter" object. You can set one of PrsBuilder objects to act as a highlighter with the help of a corresponding argument of the AddBuilder() method. +* Re-implement its virtual methods, so as to give the *MeshVS* component access to the application data model.
