Orca3D Level 2: Hull Design, Hydrostatics, Speed and Cost Analysis
In Orca3D, the hull is created as a NURBS surface. While Rhino provides many important surface creation and editing tools, Orca3D adds capabilities that are specific to hull design, such as:
- Hull Assistants, for instantly creating hulls according to a range of input dimensional and shape parameters
- Easy definition of the sections to be displayed on your hull surface; stations, buttocks, waterlines, and other planar curves. The user may specify the color of these sections, together with the layers upon which they should be placed.
- Real-time update of the sections as the hull surface is modified
- Real-time update of the hydrostatics as the hull surface is modified
- Control over the shape of the forefoot of the hull, ensuring a curvature-continuous transition from the stem to the bottom
- Easy positioning of the surface’s control vertices, either interactively, or via Orca3D’s vertex control dialog
Orca3D’s Weight/Cost Tracking module adds value to your Rhino model by assigning weight and cost parameters to the objects in the model, and summarizing and presenting the data.
“How fast will it go?” The Orca3D Speed/Power Analysis module has two different prediction methods: the Savitsky method to predict the speed/power curve for chine hulls, and the Holtrop method to predict the speed/power for displacement hulls. We have integrated the HydroComp Drag Prediction Library, to ensure reliable, accurate results.
