The Kernel Wars: A Modern Perspective Today's CAD landscape is defined by a complex ecosystem of geometric kernels and constraint solvers, each representing different strategic approaches. To better understand it, let's first look at the history of the various platforms: Fun fact: I was born in 19
The Reality Engine In 1941, Alexander Hrennikoff published a paper that would reshape human civilization. Working at MIT, the structural engineer proposed dividing complex structures into simple elements, solving each element's behavior, then assembling the results into a complete solution. He call
The Translation Engine The story of Computer-Aided Manufacturing is fundamentally about translation—converting the perfect mathematical surfaces of CAD models into the messy reality of cutting forces, tool deflection, and heat management. It's the bridge between digital dreams and physical products
Chapter X: The CAD Kernel Revolution - From Drafting Tables to Digital Twins The Geometry Engine The fluorescent lights hummed overhead in General Motors' Warren Technical Center as Chuck Eastman hunched over his terminal in 1973, wrestling with what would become the most expensive software mista
Before we wrap up the Kernel Wars, I thought it would be good to look at the hardware side of the trench warfare fought between companies we discussed such as Silicon Graphics. Here is the story of graphics adapters and AI, their unlikely beneficiary of the 21st century!
The Evolution of Graphics APIs Graphics APIs have been the unsung heroes of the Kernel Wars, serving as the critical bridge between surfacing algorithms and visual output. These interfaces translated mathematical constructs like Bézier surfaces and NURBS into renderable forms, powering CAD, visual
Equally important in the evolution of the Kernel Wars, the battle for controlling surfaces - and ultimately the automotive body industry as well as the nascent Hollywood Special Effects industry, is the history of surfacing technology. It is not only a tale of mathematical innovation—it is one of br
I have been at pains to prove that all this MCAD history is relevant to us today because the problems it solved were found to be analogous to those required for advancing artificial intelligence. The full mathematical story below.
Sometimes vendors approached the market haphazardly or did not see a technological shift, and sometimes they were too lazy to fix their bugs. This is the story of three dead ends in the history of MCAD.
At the advent of Microsoft Windows stood Jim Meadlock of Intergraph and Jon Hirschtick of Winchester Design (later SolidWorks) that saw the writing on the wall for the death of UNIX workstations. This is the story of how they got there and their very different fates afterwards.
Development of graphics kernels is pretty hard are we'll see a little later, so not everyone could afford to build their own. This is the story of a few that were modular and usable by other applications and some that stayed proprietary to their original company.
The origins of modern CAD technology come from the laboratories of computer science at the University of Cambridge. Let's explore the story.
A graphics kernel is the unsung hero of CAD systems, managing the rendering and manipulation of graphical elements. This chapter explains the DNA of MCAD applications.
