Profile: Spatial Corp. specializes in offering 3D software components for design, engineering, and manufacturing applications. The brands we offer include ACIS Modeler™. The 3D ACIS® modeler (ACIS) is a 3D modeling engine. ACIS features an open, object-oriented C++ architecture that enables robust, 3D modeling capabilities. It is particularly well suited for developing applications with hybrid modeling features, since it integrates wireframe, surface, and solid modeling functionality with both manifold & non-manifold topology , & a rich set of geometric operations. It provides a sound base of 3D modeling functionality, plus the flexibility to meet individual application requirements. The 3D Modeler also includes ACIS extensions for specific application needs including hidden line removal, deformable modeling, advanced covering and defeaturing. The HOOPS&reh; 3D application framework (HOOPS/3dAF) for 3D visualization provides the core graphics infrastructure and functionality. It enables the development of 3D visualization applications with advanced 2D and 3D graphics functionality.
