Bob Ross and The Joy of 3D Direct Modeling

Posted by John McCullough on Thu, Aug 26, 2010

John "Bob Ross" McCulloughWe've had some fun here recently in Marlborough creating a short parody of one of my favorite 'how-to' TV show hosts - Bob Ross. Check it out here - [The Joy of 3D Direct Modeling]. 

Bob had a 30-minute landscape painting show on PBS for over a decade. If you missed it, well, that's your loss. If you are interested in picking up a copy of some classic episodes check here [BOB ROSS JOY OF PAINTING SERIES: 3-HOUR WORKSHOP DVD]. He did some amazing stuff with a fan brush and titanium white. Bob's pleasant demeanor and positive commentary, which often came across as dry humor, was what made the show special. That and his hair of course.

While researching some Bob Ross quotes to use as part of the script I was reminded why I liked him. He made encouraging comments about learning painting which demonstrated a strong belief in the potential of everyone. He encouraged his students to paint from their imaginations and to not limit themselves to rigid formulas. He went on to explain how we each have a different set of eyes and all see the world differently.

I hear a lot of Bob's philosophy in the Kubotek KeyCreator 3D direct modeling philosophy. Commonly used parametric modeling software locks models to initial ideas and limits the ability to experiment with changes. The features lock models to the thought process of the initial design engineer without allowing the eyes of others to see the model as a different set of features. In contrast, 3D direct modeling is conceptually simpler and easier for new users to open up to 3D modeling. 3D modeling can be easy and fun for everyone.

Graphics Performance Across the MCAD Industry

Posted by John McCullough on Wed, Aug 11, 2010

John "Bob Ross" McCulloughOne of the MCAD industry's current most well-known writers, Deelip Menezes, recently put together a couple excellent blogs on graphics performance. Deelip recorded short videos of about a dozen CAD products dynamically rotating a complex engine model (STEP file).

I'm pleased to see that KeyCreator V9 handled the job as well as any of the products tested. Deelip looked at Inventor, Pro/Engineer, SolidWorks, SolidEdge, NX, Alibre, Spaceclaim, Rhino, and several others.

I've personally spent a lot of time this year researching graphics issues and performance. Graphics is tricky business because of the complex interaction with hardware, which is 'highly non-uniform' across our customer base. The changes Microsoft has introduced in Windows 7 have presented new challenges for us. However, Microsoft's push in these areas and advancement of DirectX has created an overall performance gain for Kubotek graphics using the Direct3D driver type.

Its gratifying to see that Kubotek is already providing excellent performance compared to the rest of the industry because we are also not resting. For V10 we have a number of significant graphics related changes coming to improve performance even further.
