Hull Design | Hydrostatics and Stability | Resistance and Power Prediction | Surface Modeling | Subdivisions

FreeShip Plus modeling kernel is purely based on subdivision surfaces. It uses a mixture of loop subdivision and Catmull Clark subdivision surfaces called quad-triangle subdivision. This enables the user to design the most complex surfaces with only one surface.

Control points can be added in areas only where they are needed. Holes and knuckle-lines are easily incorporated. The number of control points may be drastically reduced compared to classical NURBS surface modeling.

Intersection lines such as stations, buttocks and waterlines may be added to the model and are updated realtime when a control point is being dragged. Adjustable precision by controlling the subdivision level. An integrated shading engine provides stable software rendering without the need for 3rd party software or dll’s.
