Fire At Saatchi Warehouse

Art-like objects destroyed including Hirst and Chapman products:

Hope none of the good stuff was damaged. Do they make flame-retardant canvas?

Creative Commons 2.0 Licenses Are Out!

The Creative Commons 2.0 licenses are out.

They cover music and combining works much better than the 1.0 license, but miss the crucial “representation of authority to contribute” clause that makes people think about whether they really are allowed to release Star Wars as Open Content. This was too strict in the original license, but is present in a milder form in several other licenses, and should have been kept in a watered-down form IMHO.

If you are making music or want a good license that allows the kind of cross-media explosion that Lawrence Lessig’s “Free Culture” has seen, this is the license for you. If you are concerned about preventing the SCOs of this world attacking Free Culture, the Free Software Foundation’s procedures for handling contributions may provide a good model.

Congratulations to the CC team for getting these licenses out and for robustly enabling cross-media Free Culture.

Draw Something More

The next thing I want to get Draw Something to do is to assemble and draw figures made from several simpler shapes.
The current system starts with a set of random points (or lines, depending on how you look at it), finds the “convex hull” (the simplest shape that contains them), then draws around that. This is a very, very simple analogue to constructive drawing for illustration where shapes are built up around a skeleton or armature and then drawn around to construct a figure. It is a similarly simply analogue to artistic observation and rendering of some part of the visible world.
Following these comparisons, Draw Something assembling simple shapes (convex hulls again) into more complex figures will trivially model assembling or revising a composition from preparatory sketches. The shapes will be generated randomly on the page then moved into position so that they all overlap (making multiple figures is a future task). I like the idea of drawing the starting lines and hulls in light blue, the assembled hulls in darker blue (or red), and the finished outline in black to show how the figure has been assembled (the colours come from drawing for animation).
I was worried that this was an arbitrary task to set the program until I realised that making simpler shapes, composing them and outlining them is exactly how I constructed my “Blobs”. So in fact this is a task I have productively set myself in the past, and it will be interesting to see what Draw Something makes of it.

Minara In Progress

I’ve finished most of the object picking code I need so far, just line and curve intersection to do (these are well-known standard algorithms. The curve one I’ll implement in C for speed). They’ll be as sloooow as I expected: rendering the scene to find where the graphics are under the mouse then doing a text search of the image source to find this point in the program is insanely inefficient. And how we’ll handle symbols and functions I don’t know (keep hashtables of each and have some sort of lookup scheme, probably, with the user responsible for writing picking versions of functions as a worst case).

I’m doing less well with colour. I’ve got LittleCMS, but the idea of having colour primaries as gamut-limit XYZA tuples means that gamut checking hopefully isn’t a problem. What LCMS could be useful for is mapping the abstract percentage of the colour to the actual strength of colour on the screen or the press, which won’t be linear. But I don’t know if I want to do that just yet.

How do we do colour picking? Make an image with percentages of each of the primaries in, display that, and update the mix when the user clicks, accepting when they double click. Who needs GUI widgets? 🙂

Hackers And Painters

Hackers and Painters is out. It looks good. I’m just waiting for Amazon.uk to get my copy past the tachyon projectors.

Wired has a good review

Sample chapter, “hackers and painters” (pdf).

See the book site for more details and reviews.

More Paul Graham essays can be found on his web site.

Now if he can just get on with Arc… 🙂

Eating My Own Dog Food

“1968” needs finishing. It’s colour that’s the problem. I want a more fluid and accurate way of working with colour than the current crop of illustration software gives me.
Minara needs continuing. it needs real tasks and projects to work on.
So I’m going to write the bits of Minara I need to edit “1968”. Defining colours, managing colour accuracy, and possibly hit-testing will all be needed. I’ll also have to make sure the import filter works well to convert 1968 to minara format.
In software engineering jargon this is known as “eating your own dog food”. Yum.

EU Copyright Diktat

The unelected European Commission, under the Microsoft-sponsored Irish presidency, has voted in favour of software patents. This is despite the European commission (the elected government) voting against them
Software patents sound like they protect people’s ideas but they don’t. They stifle competition, reduce choice and as more and more of our business and culture becomes digital, they impose a burden of cost and control on our day-to-day lives.
See FFII for what we can still do to stop this idiocy.

The Ontology For “Draw Something”

I’ve started working on the ontology for my program “Draw Something”. It’s currently based on my unpublished “ae” toy aesthetic program, but I need something heavier duty for the full program.
In computing an ontology is data that represents knowledge, particularly facts and rules. So for a medical program, the ontology would contain information about which drugs treat which conditions, and how those drugs interact. In philosophy, ontology is the metaphysics of being and categories of being. Both meanings are applicable to Draw Something’s ontology; it’s a computer representation of an investigation into what art is and how you produce art-objects.
I have a certain way I want Draw Something’s ontology to work – more as active “daemons” than as passive symbols. I’ve been looking at Paul Graham’s writing on “closures” in his book “On Lisp“. Closures combine data and instructions in a more active way than other programming techniques do, but I’m not sure they’re what I need (in particular I don’t know how to copy closures in a program or get polymorphic behaviour from them). And very few people understand closures. And I’m not really one of them yet. 🙂
My favourite type of ontology is Douglas Hofstadter’s slipnet, as seen in his & Melanie Mitchell’s “CopyCat” program, explained in “Fluid Concepts and Creative Analogies“. A slipnet allows more specific ideas (“the number 5”) to be generalised to less specific ideas (“numbers”) if the a particular problem cannot be solved with more specific ideas. Copycat also has a nice split between its built-in concepts and its current working memory. Hopefully this will be a useful model to use for Draw Something.

Aesthetics Is Subservient to…

(From Aesthetics-L)

I look forward to the first book on art by a chef. We will find that
aesthetics is inferior to cooking, that pigments are inferior to
spices, that the gesamtkunstwerk is a sizzling platter, and that
criticism should be replaced by large gratuities. Sadly this is
self-undermining, as the chef must themself eat.
