Core Component

The Core Component includes basic services for other components, such as classes for handling strings, math, variants, smart pointers, etc. It also includes a system for logging and a system for license control. This component does not depend on OpenGL support.

Features

  • String class with Unicode support. Converts to/from STL string classes std::string and std::wstring
  • Variant and property system
  • Basic math classes for 2D and 3D vectors, 4x4 matrices, symmetric tensors and planes
  • Logging system used by all Ceetron 3D Components that can be controlled and used in your own application
  • License control. Handles licensing of Ceetron 3D Components (both evaluation and permanent licenses)
 

Visualization Component

CeetronVisualizationComponent picThis component can handle analysis models with 10s of millions of finite elements and more than 1 million geometry parts.
 
The Ceetron Visualization Component is the main component for visualization applications. It supports simultaneous visualization of multiple data models, multiple viewports, camera positioning and various user interaction mechanisms.   

Picture to the right: Ceetron 3D Components has a rich set of high level features to display quantitative information such as distance between two points, angle between two lines, etc. Information can be display in the geometry using a rich set of annotations. 

Shaders are fully implemented to take advantage of the latest developments in graphics hardware and middleware. 

The View in the Visualization Component can show models from any of the other components, and can thus combine analytical geometries and FEA analysis meshes creating a more impressive user experience.

Geometry Component

The Geometry Component offers a data model for geometries containing a large number of parts (grouping of elements, typically with different attributes). The Geometry Component is specifically designed for efficient handling of complex geometries.

  • High Performance model for efficient handling of many parts
  • Handles 1M+ parts
  • Efficient effect system for controlling visual attributes
  • Front and back colors and opacity
  • Easy to override effects
  • Full texture support
  • Simple result visualization via textures​​

  ​
Pictures to the right: The Geometry Component is tailored to handle simulation models with a large number of parts efficiently. Models such as the snow scooter (top right) and the oil rig (bottom right) contains several hundred thousands of parts are handled with little or no overhead compared to a single part model. 


 

UnstructGrid Component

3D-UnstructGrid-Components_pic5
The UnstructGrid Component provides a high-level interface to flexible data structures which allow the user to populate the data model with native finite element model and results data structures and apply an extensive set of feature extraction algorithms to the data. Scalar, vector and tensor results are provided through a high-level programming interface as well as feature extraction algorithms such as cut-planes, isosurfaces, isovolumes, particle traces and other advanced result presentations.  

Picture to the right. High level functions for advanced result visualizations are available in the Unstruct Component.A scalar plot (top right) is available using a single function call. Any result visualization can be displayed using e.g. transparency for improved result interpretation for complex geometries.

UI toolkit integration

Ceetron 3D Components is platform neutral and UI toolkit neutral and can be integrated with any UI toolkit. The only requirement is that the target platform supports OpenGL.

The C++ version is delivered on Windows (32 bit and 64 bit), Linux (64 bit), and Mac OS X. It comes with ready to use platform integration sources and examples/tutorials for Qt (both Qt4 and Qt5), wxWidgets (3.x), MFC and Win32. It can also be integrated with any UI toolkit following the same scheme as demonstrated for example for Qt in the platform integration sources.

The .NET version (32 and 64 bit) of Ceetron 3D Components has the same performance and capabilities as the C++ version, but has also some extra features (e.g., properties) to help C# developers.​​
