Hockney again.

I went to see the Hockney A Year in Yorkshire exhibition yesterday at Annely Juda. Further thoughts about “representational painting and the 2D simulation of reality. When I was young, I secretly liked Atkinson Grimshaws paintings best of any Id seen, though my knowledge of them was limited to the one or two on display…

Nolls Mondrian Machine/ Shaws Golden Calf.

Im reading about digital art, and looking at some of the early examples. Michael Nolls picture Computer Composition with Lines” was a computer generated picture resembling Mondrians 1917 painting, “Composition with Lines“. Jeffrey Shaws virtual sculpture “The Golden Calf“, 1994, was a virtual calf mounted on a real pedestal. Nolls Mondrian clone was not simulation…

See this earlier posting on high speed computers. The BBC piece lists possible uses for this sort of speed as simulating nuclear weapons tests,…

The video deficit ws first described in a paper in 2005: “studies find negative associations of (TV) viewing with language,…

A historical perspective on simulation.

Ive just been reading the powerpoint of a paper given at the Winter Simulation Conference 05 by C Dennis Pegden. It makes several interesting points very concisely about the recent history of simulation. The Early Years (1960’s) saw the birth of modeling concepts, using event Modeling (Simscript), Process Modeling (GPSS), and Object Modeling (Simula). Limited…
