Framework: MODELER

Advanced Modeling Tool Set

Sim4Life integrates a powerful parametric 3D modeling environment based on the ACIS toolkit for generating advanced interactive CAD models and high quality surface models from segmented image data, for example. The fast OGL- and VTK-based rendering engine allows interactive visualization of large and complex volumetric data sets and CAD models. Specialized tools will be continually provided upon user request to handle specific tasks, such as vasculature modeling and processing.

Sim4Life facilitates the placement of detailed CAD pacemakers in complex anatomical models.

Provides integrated, advanced, and interactive CAD modeling without the need for a preprocessor or live-link; and handles complex anatomical models, e.g., ViP models and massive CAD models.

The only simulation software capable of converting triangular surface meshes into parameterized CAD models, e.g., NURBS-based.

Offers integrated functionality to extract, smooth, and simplify tissue and organ surfaces from segmented medical image data.
