Icona Solutions has announced the availability of the latest Aesthetica perceived-quality simulation and visualisation software.

Aesthetica applies manufacturing tolerances and component location schemes directly to 3D computer-aided-design (CAD) models and simulates assembly deformation to enable true-life perceived-quality studies using realistic imagery, early in the product development process.

Aesthetica Version 3.2, a full, native 64-bit version, features enhanced perceived-quality scenario capture functions, an updated JT import module and improved 3D CAD model tessellation processes.

It also includes a trial version of a production prototype interface to RTT Deltagen, an interactive realistic visualisation solution.

The introduction of a native 64-bit version of Aesthetica, which takes advantage of the latest 64-bit computing platforms, brings benefits in terms of the size and complexity of CAD models that can be handled by the software.

The model size that the 32-bit version can handle is limited to less than 3Gb, regardless of how much memory is installed in the machine; however, the new 64-bit version can utilise all available memory, enabling it to work with much larger and more detailed 3D CAD models.

In addition, Monte Carlo analysis and model deformation is performed up to 25 per cent faster in the 64-bit version, depending on the model size and complexity, while more detailed polygon models can be produced for more accurate visualisation results.

The 64-bit version also enables larger material sets and textures to be created for use in the visualisation process.

The enhanced scenario capture functions enable users to capture gap and flush target scenarios (that is, what is desired from a perceived-quality viewpoint) along with tolerance scenarios (what you will actually get), all combined within a single window.

Users can automatically capture as many target/specification and/or simulated scenarios as required, together with viewing points, materials and textures, and then instantly recall these scenarios during a perceived-quality review meeting.

The captured scenarios can also be exported directly to selected third-party visualisation solutions.

This eliminates the need to set up individual variation models within these third-party solutions, reducing the time required to produce high-end visualisations for management and executive reviews or for customer clinics.

Improved 3D CAD model tessellation processes introduced with Aesthetica 3.2 produce crack-free polygon models by identifying shared edges between surfaces during tessellation and healing the surfaces to create a seamless polygon model.

This results in higher-quality visualisation and smaller file sizes, according to the company.

The existing JT import module for Aesthetica has also been updated to take account of the latest version of the JT format, with support for the NX v5 and NX v6 CAD/CAM software from Siemens PLM Software.

Users who choose the 32-bit version will also benefit from general software optimisation, which delivers overall performance improvements of around 20 per cent to 50 per cent compared with the current version, depending on the operation.

An optional direct interface to the RTT Deltagen high-end, realistic visualisation software solution is introduced as a production prototype with Aesthetica 3.2.

This interface will be ready for full product release in summer 2010.
