Subdivision Surfaces

Along with speed and interactivity improvements to the NURBS fitting, CySlice v3 features the new Subdivision Surfaces (SUBD) fitting tool.

SUBDS are becoming widely accepted in the CGI community as an alternative to NURBS. They have none of the tangency/cracking problems experienced by NURBS during animation, and SUBD modelers are freed from the "rectangular patch" topology restrictions of NURBS surfaces.

CySlice v3 allows users to fit SUBD surfaces to dense polymeshes, and as with the NURBS fitting tools, color and bump/normal/displacement maps can then be calculated. CySlice v3 outputs the same Catmull-Clark variety of SUBD surfaces that Maya and Renderman uses. A sample SUBD surface is now ready for download from the headus website.

Surfacing

CySlice retains all of the capabilities of version 2, so the user can easily generate IGES 128 NURBS surfaces from any Ply file. Cyberware also provides translators to convert STL (Stereo Lithography) and OBJ (Alias/Wavefront) files to the Ply file format, opening up CySlice to users who do not necessarily use a Cyberware Rapid 3D Digitizer. The software allows the user to create NURBS surfaces in a free-form manner. Also the user can manipulate any portion of the surface at any time; UV density can be altered, boundary curves can be modified by moving existing control and end points, or by adding or subtracting control points.

CySlice also allows the user to save a template surface. This feature allows the user to define a template for an object that contains all of the control points, boundary curves, and surface parameters. This template can then be applied to any similar object so that the user need to create a surface only one time, apply that surface to subsequent models, thus saving many hours of user interaction.

Slicing

CySlice is used to extract polylines and splines from polygonal meshes. These polylines or splines can then be imported into modeling software as an aid to the construction of spline surfaces.

You can either cut a whole lot of equally spaced parallel sections through the polygonal mesh, or draw individual slice lines along key features. These slices can then be edited for consistent start points and direction. And finally the slice lines can be interpolated with reduced vertex count polylines (IGES 106), or with NURBS splines (IGES 126).
