Nurbs Object
The NURBS Object in Architron is an implementation of Non-Uniform Rational B-Splines (NURBS) within Cinema 4D, and it serves as the foundational element for all parametric objects in the plugin.
This object is derived from the Cinema 4D geometry object and encompasses a full suite of NURBS geometry.
It provides users with standard editable curves, surfaces, and polygons, making it a versatile tool for detailed architectural modeling.
In the current version of Architron, the NURBS Object is limited to editable NURBS curves and non-editable parametric NURBS objects, offering a focused and specialized toolset for architectural visualization!
Key Parameters:
Object:
Output Geometry: Switch between 'Curves' and 'Surfaces' to specify the NURBS output.
Nurbs Detail: Input to adjust the detail of NURBS geometry; higher values equal more detail.
Fix to Parent: Ensures the NURBS object's position matches that of its parent when active.
Ground Axis: Dropdown menu for selecting the object's ground axis orientation.
Flat Ground: A parameter that, when enabled, influences UCS and tool behavior, generating UCS based on the selected Ground Axis.
Import Nurbs: Imports NURBS data into the object from a specific file format.
Export Nurbs: Exports NURBS data from the object into a specific file format.
Analyze Nurbs: When checked, it activates additional visualization tools for assessing geometry indexes and properties, useful for in-depth geometry analysis.
Analyze:
Show Point Id: When activated, displays the identifier for each control point in the NURBS geometry.
Show Edge Id: Enables visualization of the identifiers for edges in the model.
Show Element Id: Allows for the display of identifiers for individual geometric elements.
Show Iso Points: Toggles the visibility of iso-parametric points, which are points of constant parameter on curves or surfaces.
Show Knots: When checked, the knots of the NURBS curve or surface are displayed. Knots are points that define the division of the curve or surface and influence its shape.
Show Knot Values: Displays the numeric values associated with the knots in the NURBS geometry.
Show Inflection Points: Enables the identification of inflection points where the curvature of the NURBS curve or surface changes sign.
Show Open Curve Ends: When enabled, the ends of open NURBS curves are highlighted for clarity.
Show Loop Disconnections: Toggles the visibility of disconnections in looped NURBS curves, which can be critical for troubleshooting complex geometries.
