• May 92 – First meeting with AG. Applied Geometry (AG) came to us for assistance in integrating their AGLib, NURBS geometry library, in AutoCAD. AG customers included Alias Research, Spatial, Honda, and Tecnomatix
• Jul 92 – First prototype in AutoCAD after about 3 days of work.
• Nov 92 – McNeel/AG agreement to develop AccuModel, NURBS modeling for AutoCAD. McNeel would do the marketing and AG would do all the development. McNeel would provide AutoCAD development support as needed.
• Nov 92 – Michael Gibson hired as an intern. He brought Sculptura, a mesh modeler that he had done as a class project.
• Mar 93 – Sculptura released.
• Mar 93 – McNeel takes over as the lead on the AccuModel development.
• Jul 93 – First prototype of Sculptura 2 ready for NURBS.
• Nov 93 – Sculptura 2 nicknamed Rhinoceros.
• Jan 94 – New McNeel/AG agreement where McNeel was licensing AGLib from AG and AG would provide the needed AGLib enhancements and maintenace.
• Apr 94 – Rhino beta released on the Graphic Alternative BBS. This was our first version of a public beta program.
• May 94 – Dr Dale Lear hired from AG. We had found that we needed geometry expertise in house in order to develop the functionality and usability needed by our clients.
• May 94 – Alias Research agrees to purchase AG. Alias was AGs largest customer and they felt that one of their advantages was the geometry technology.
• May 94 – First commercial products completed using AccuModel. Ed Monk & Son Navel Architect released an 82 foot sports fishing boat.
• Jul 94 – Geometry development begins in earnest. Alias didnt seem to be interested in the geometry library business.
• Aug 94 – Sculptura renamed Rhinoceros after it was determined that we would not be able to reslove the trademark problems with AccuModel.
• Aug 94 – Private showing of Rhino at SIGGRAPH.
• Nov 94 – Sale of AG to Alias final.
• Mar 95 – McNeel provides Alias with first installment of geometry technology.
• Jun 95 – Alias purchased by Silicon Graphics.
• Jun 95 – McNeel receives the last update of AGLib.
• May 97 – Last build of AccuModel for AutoCAD. As the Rhino product progressed we decided that it would be better to focus on the Windows version.
• Sep 97 – 50,000 beta sites and growing fast without any promotional effort on our part.
• Jul 98 – 100,000 beta sites.
• Jul 98 – Announced Oct release at SIGGRAPH.
• Oct 98 – Release Rhino version 1.0.
• Dec 98 – First 5,000 shipped.
• Jan 99 – Japanese version released.

• May 99 – Korean version ships.
• Aug 00 – First public beta of 2.0 and Flamingo released.
• Sep 01 Shipping Rhino 2.0.
• Nov 01 Shipping Flamingo.
• Nov 01 Inside Rhinoceros published

Quotes:

I first sculpted an ear from a modeling clay, sliced it like a birthday cake and visually “digitized” the sections into Rhino. I used Curve->Freeform->Control Points to draw the section curves. All sections must have the same number of points and the points of all curves must be visually in sync with each other. I rotated the sections in place and used Loft with Closed Smooth option to create the initial ear surface. Rubencito

steps

Steps:
1.Path Curve.

2.Spiral curve (Command: Helix, Around the path curve).

3.Orient the profile curve on the path curve. (Command:OrientOnCrv with Perpendicular option)

4.Sweep along 2 curves, select path & Spiral curves as the rails.(Command:Sweep2)

===Description===

Software : Rhinoceros & Grasshopper (Explicit History)

Basically the idea is to drive the radius of the circles with the distance between the point(s). The circles then use the MIN component and a range factor to limit how big the circles can get as well as the area of influence of each point.
