What is Rhino?
Rhino can create, edit, analyze, and translate NURBS curves, surfaces, and solids in Windows. Rhino has limited support for polygon meshes. There are no limits on complexity, degree, or size.
NURBS
Non-Uniform Rational B-Splines (NURBS) are mathematical representations that can accurately define any shape from a simple 2-D line, circle, arc, or box to the most complex 3-D free-form organic surface or solid.
Because of their flexibility and accuracy, NURBS models can be used in any process from illustration and animation to manufacturing.
Features
- User interface: extremely fast 3-D graphics,
unlimited viewports, working perspective views, coordinate
read-out, named views, named construction planes, customizable
icons and user workspace, extensive on-line help, electronic
updates, newsgroup support.
- Construction aids: unlimited undo and
redo, exact numeric input, object snaps, grid snaps, ortho,
planar, construction planes, layers, background bitmaps,
object hide/show, object lock/unlock.
- Create curves: point, line, polyline,
free-form curve, circle, arc, ellipse, rectangle, polygon,
helix, spiral, conic, TrueType text, point interpolation,
control points (vertices), sketch.
- Create curves from other objects: extend,
fillet, chamfer, offset, blend, from 2 views, cross section
profiles, intersection, contour, section, border, silhouette,
extract isopram, projection, pullback, sketch, wireframe,
detach trim, 2-D drawings, flatten developable surfaces.
- Edit curves: control points, edit points,
handlebars, smooth, fair, change degree, add/remove knots,
add kinks, rebuild, refit, match, simplify, change weight,
make periodic, adjust end bulge, adjust seam.
- Create surfaces: from 3 or 4 points,
from 3 or 4 curves, from planar curves, rectangle, extrude,
ribbon, rule, loft, sweep along a path, sweep along two
rail curves, revolve, rail revolve, blend, patch, drape,
point grid, heightfield, fillet, chamfer, offset, TrueType
text.
- Edit surfaces: control points, handlebars,
change degree, add/remove knots, match, extend, merge, join,
untrim, rebuild, shrink, make periodic, Boolean (union,
difference, intersection).
- Create solids: box, sphere, cylinder,
tube, pipe, cone, truncated cone, ellipsoid, torus, extrude
planar curve, extrude surface, cap planar holes, join surfaces,
TrueType text.
- Edit solids: fillet edges, extract surface,
Booleans (union, difference, intersection).
- Create meshes: from NURBS surfaces, from
closed polyline, mesh face, plane, box, cylinder, cone,
and sphere.
- Edit meshes: explode, join, weld, unify
normals, apply to surface.
- Edit tools: cut, copy, paste, delete,
delete duplicates, move, rotate, mirror, scale, stretch,
align, array, join, trim, split, explode, extend, fillet,
chamfer, offset, twist, bend, taper, shear, orient, flow
along curve, smooth, project, object
properties.
- Analysis: point, length, distance, angle,
radius, bounding box, normal direction, area, area centroid,
area moments, volume, volume centroid, volume moments, curvature
graph, geometric continuity, deviation, naked edges, nearest
point.
- Rendering: quick shade, full shade with
textures, spot lights, and shadows, and customizable resolution.
- File formats supported: DWG, DXF, 3DS,
LWO, STL, OBJ, AI, RIB, POV, UDO, VRML, BMP, TGA, JPG, IGES
(Alias, Ashlar Vellum, AutoShip, Breault, CAMSoft, Catia,
Cosmos, FastSurf, Intergrity Ware, MasterCAM, ME30, Mechanical
Desktop, Microstation, NuGraf, Pro/E, SDRC I-DEAS, Softimage,
Solid Edge, Solidworks, SurfCAM, TeKSoft, Unigraphics).
- File management: Notes, templates, merge
files, and export selected objects.
- I/O plug-ins: 3D Studio MAX, Softimage,
and programmer's I/O tool kit with source code.
- 3-D digitizing support: MicroScribe 3D
and Faro Space Arm.
