Light

• AddPointLights — Batch add point lights to Rhino documents based on input points.
• AddRectangularLights — Batch add rectangular lights to Rhino documents based on input geometry.
• AddSpotLight — Batch add spotlights to Rhino documents based on input position and orientation.

Math

• ClosestOddEvenNumber — Find the odd and even numbers that are closest to the target value.
• Value Quantization — Replaces values within the specified range with the nearest value in the custom target list, leaving the values outside the range unchanged.

Mesh

• CurveProjectToMesh — Projects a curve to the mesh in the specified direction.
• MeshEdgeSelect — Filter mesh edges based on the angle between adjacent mesh faces.
• MeshExplode — Split the mesh into independent parts based on angular tolerances.
• MeshLoft — Generate a mesh from a set of polyline lofts.
• MeshPipe — Generate meshed circular tubes along curves.
• OffsetMesh — Offsets the mesh along the vertex normal direction.
• SplitMeshWithProjectedPolylines — Split the mesh using polylines projected onto the mesh.
• Tween Mesh — Interpolate corresponding vertices between two topologically compatible meshes to generate a transition mesh.

Points

• PointGroup — Divide points into groups based on the distance between them.
• Sequential Closest Projection — The starting point is projected to the nearest point of the curve list in sequence, and the projection can be continued after moving along the tangential direction of the current curve at fixed intervals.

SubD

• CreaseVertex — Sets the specified SubD vertex to an acute vertex.
• SubDToBrep — Convert SubD object to NURBS Brep.

Surface

• ExtendSrf — Extends the surface in the specified direction.
• OffsetBrep — Offset Breps or polysurfaces and produce solid results.
• ShrinkTrimmedSrf — Shrinks the underlying surface of the trimmed surface to the trimming boundary.
• SplitBrepByCrvs — Split the Brep using curves lying on the surface.
• Tessellate NURBS — Generate parametric pavement panels on NURBS single or polysurface surfaces.
• Tween Surface — Reconstruct a NURBS transition surface between two surfaces by interpolating corresponding sample points.
• Unroller — Unfold single or polysurfaces and output the corresponding unfolded geometry.

Text

• FilterTextAndNumbers — Filter and separate text content from digital content.
• FontTable — Read the list of available fonts and distinguish between Chinese and Western fonts.

TextureMapping

• ApplyBoxMapping — Applies a box texture map to the object.
