XirusCAD Technology

XirusCAD® simulates immediate responsiveness to tangents, curvature, derivatives, junctions, boundaries and smoothness and provides direct control to adjust the quality of the surface anywhere on the object. Xirus® allows the user to exactly convert the geometry to NURBS or polygons at any moment during the CAD process.

Mirrakoi®’s 3D geometric kernel offers unsurpassed interaction functionality with 3D digital objects during the shape modeling process. Mirrakoi®’s technology enables a superior modeling experience that results in reduced labour, time, and challenges that are encountered in today’s CAD and CAE processes.

Mirrakoi®’s technology is the outcome of fundamental mathematical research. It is distinguished by four key attributes:

  • unprecedented interaction functionality enabled by augmented CAD
  • superior geometry representation
  • increased efficiency and speed when modeling digital high-quality industrial surfaces
  • guaranteed interoperability with industrial standards (100% NURBS and polygon compatible).
