Since early 2025, LEDAS, a leading provider of engineering software R&D services and a developer of 3D computational components, has been participating in a brand-new 3D modeling project.
This project focuses on modeling smooth 3D solids and surfaces of the highest quality, both technically and aesthetically. On the technical side, the modeling engine is designed to minimize aerodynamic resistance, thereby reducing energy and fuel consumption and operational costs—a critical advantage for automotive, aerospace, and other industries involving moving vehicles. To enhance aesthetic appeal, the engine utilizes G1, G2, and G3 continuity classes, ensuring exceptionally smooth transitions between surfaces. The related geometric operations include creating smooth free-form surface connections, generating specifically parameterized fillets on edges, filling gaps between existing geometries, and more.
In this project, LEDAS leverages its extensive expertise in free-form modeling, particularly NURBS-based techniques. We develop and use advanced approximation and extrapolation methods, solve systems of differential equations, and apply classical NURBS algorithms to deliver highly efficient modeling technology. Analysis and control of smoothness and various types of curvature are cornerstones of this project, and LEDAS is building all the necessary tools for this.
LEDAS has a long track record in developing state-of-the-art 3D modeling solutions. Our portfolio includes several 3D modeling kernels, numerous geometric constraint solvers, a polygonal mesh-to-B-rep converter, collision detection systems, a proprietary geometry comparison tool, and many other software products and components. While boundary representation (B-rep) 3D solid modeling remains our primary focus, we also possess deep expertise in polygonal modeling, surface modeling, point clouds, and depth images, with over 100 person-years of cumulative experience in these fields.
