Open Source Values

Friday, April 30th, 2010

I am a firm believer in the open source movement and specifically Creative Commons licensing for creative works. I have been publishing this blog under a creative commons license for years giving away content, as most blogs do, without concern for making money. Credit yes. Money, no. The benefits I have received far outweigh what money could have been made had I tried to monetize this. The purpose for me writing this blog is fun and enjoyment.

Because I work as a professional artist I have found it important to have a creative outlet that is not tied to income. While I would certainly welcome a book deal, I am not about to go seek one out. I enjoy having a space wherein I can create without the pressure that money brings to a situation.

In my theater work I have provisions in my contracts to protect my work on a show. They state that if the show gets picked up by a larger producing organization I get the first right of refusal to be hired as the lighting designer for the next incarnation of the show. They also state that the lighting design, drawings, etc belong solely to me.

From an ethical standpoint I find myself posed with a bit of a dilemma. On the one hand I need to eat and ensure that I can continue to do so. On the other hand I want to remain true to the values of open source thinking. Because my theatre work is contract work for hire, rather than solely generative art, I am able to make a mental distinction that allows me to go on with my life in a state of ease. But it makes me wonder, what would open source performance look like? Is it possible in a collaborative art form or is the collaborative nature of theatre and opera inherently open source?

At a certain level theater does have an inherent open source component to it. Plays, opera scores, and ballets whose copyright has expired are ripe for remixing and reconceiving by contemporary artists. This happens all the time. While one could point to an obvious example like the Wooster Group’s Hamlet, every remount of a play or opera is a remix of the original.

Works in repertory, like opera or ballet, have an element of the open source ethos in them every time they are remounted. The lighting supervisor, who may well have not been born when the original lighting designer created the work, must reconstruct the thing using new lighting instruments colored with gels by companies which were not around at the time of creation. There is always a degree of interpretation in these moments, sometimes quite severe transformation, yet the by line will always read “Lighting by Original Designer” no matter how much the work has changed over the 10, 20, 80 year lifespan of the piece.

Repertory lightplots carry this same quality of a remixed open source code. Jean Rosenthal’s plot for New York City Ballet was updated by Tom Skelton and has been updated since. Many of the same ideas and structures are still in place now as were then. While the plot may not be attributed to anyone but the current lighting supervisor, the source code, as it were, could be traced back to the work of Jean Rosenthal.

While these are all elements of performance which have an open component to the code or structure, it does not get to the idea of the whole process as open source. The financial aspect of making work complicates a truly open source approach. It would be hard to relinquish one’s rights to a design for a show and then be the only one not to travel with the new production uptown. Or if the drawings and documentation were released with a production it could be difficult to see your work applied poorly and then be given credit for it.

But these concerns are egoic and have nothing to do with the efficacy of the potential project or the artistic validity of such an endeavor. For something like this to work it would require the full compliance, if not enthusiastic support, of a rather large number of individuals. Merely gathering such a group together would pose quite a challenge. But the novelty of the exercise could well be worth it.

Product Review – Vectorworks 2010 Part 2: 3D Drafting and Basic Rendering

Monday, April 26th, 2010

As I said in Part 1 of my review, Vectorworks 2010 is a fantastic program for drafting lightplots. But there is much more to the program’s functionality than 2D lightplots. I finally had some downtime this past week to sit with Vectorworks 2010 and get to know it a little better. Up to now I had not gone very far into the functionality of the program and was using it as little more than the rather old version (V10.5) I had been working with prior.

I began working my way through the training manual that came with the program and was given a lot of basic exercises to learn different tools. Basic 3D extrudes, 3D reshaping, curves, and so forth. I was blithely working with these simple shapes when I came to the first big project in the training manual.

Draw a lighthouse.

Presented with an architectural drawing you are tasked with drafting and then rendering the object in 3D.

My first reaction was “there is no way in hell I can do that.” But after taking a second look at the drawing I realized it can be broken down into more or less basic shapes which can be dealt with on an individual level rather easily. Just as I break down the drafting of a lightplot into smaller manageable chunks, so too did this appear much easier once I took that route with the Lighthouse.

I have worked with Vectorworks for over a decade. In that time I have done very little architectural style drafting. From my background of drafting lightplots, the use of symbols became readily apparent as the way to make this project work. Much of the drawing would be composed of a few symbols that repeat and then a handful of sweeps and extrudes.

The most complex shape to deal with, far and away, was going to be the iron supports underneath the first landing. Not only is the basic outline a complex shape with various curves and corners, but it is cut out and recessed in multiple places at varying depths. This is also what makes for a very good learning project. There is a single, very difficult, challenge and then the rest of the project is working with rather basic skills in a more complex way than the previous simple shapes exercises.

My mindset going in to this work was that I was learning a whole new computer program. The upgrade from V10.5 to 2010 is huge and it was far better to treat my knowledge base as coming from a different program. That mindset served me well.

The Spotlight manual is written in a very clear and easy to read manner. I had done the short version of the manual when I first got the program and drafted a simple 3D theater with lighting positions. But that hardly gets at much of what is good with this program.

Wrapping my brain around 3D space took some effort, as did parsing what would be the best way to achieve a particular goal. Some shapes made more sense to create as sweeps while others were better suited to be extrudes along a path. While the manual does not tell you what is best, after some trial and error I began to get a sense of the, sometimes subtle, differences between the two modes of working. The roof and spire were clearly better suited to sweeps, while the floors for the various levels had a bit of a question to them. Should I continue the floor all the way to the center point, or create a circle and extrude along that path? Because this project had a lot of those situations and many circular shapes to work with, I got a lot of experience in determining when one would use one tool or another.

The manual is written clearly. Thus it should be no problem for a novice, or someone upgrading from a much older version like I was, to dive right into the program and begin to do some fun and interesting work.

A tool that was new to me, which I found radically useful on this project, was the snap lupe [Z]. It is not a tool that is very necessary for the drafting of lightplots, but for these more complex and detailed drawings it is an invaluable addition to the Vectorworks tool set.

The exercise itself did not cover renderworks textures or lighting renderings (topics that are covered later in the tutorial) but I was able to stumble my way through some elementary uses of these tools thanks, in no small part, to the clear and well designed user interface of the program.

After working through this next level of exercises I have to say that I would strongly encourage anyone with the means to do so (and I understand that the program is very pricey for many) to consider the upgrade to 2010. The functionality has vastly improved as has the UI.

Along with my Vectorworks upgrade in February, I had upgraded my laptop in January. Before the new laptop, doing any sort of 3D modeling was a bit of a hassle as the rendering time was tedious. While the file I worked with for this review was in no way huge, the faster processor certainly helped make the 3D work a pleasure. If you are planning on an upgrade and getting into the 3D modeling I would strongly encourage you to make sure your computer’s processor is up to speed, and upgrade as necessary. VW2010 is a powerful program, but it needs a strong computer to do that work.

Product Review – Vectorworks 2010 Part 1: In the trenches

Friday, February 26th, 2010

I received my new copy of Vectorworks 2010 right in the midst of drafting several shows on top of one another. Never one to turn down a challenge, I installed the software, ported over my symbol libraries, downloaded my two main plug-ins (Autplot Tools for Spotlight and Beam Draw) and went to town. It took me an hour or so to rebuild my custom palettes, menus, and get used to the new placement of a few critical keyboard commands (must remember “H” is now the grabber tool). Once that was done I was ready to get to work.

Since at its core what I need Vectorworks for is to draft lightplots I figured the best test would be this plunge into the deep end of the pool. I plan to cover more of the functionality of this software in later parts to this review. As a basic drafting machine for the creation of lightplots Vectorworks 2010 is fantastic. I thought the process of my upgrade might be of interest to readers so I will begin there.

The first thing I noticed was the visual design. It is quite beautiful. The images for tools in the palettes are very clear and distinguishable as well as good looking. While non-essential to getting work done, it does make a big difference when you are staring at a computer screen for eight or ten hours a day. A small change around tools that I found incredibly useful was the fact the the program now remembers your last choice for tool options rather than returning to a program default every time you launch the software. For example, I often use the mirror tool to layout sidelight systems. The system default is mirror mode but I need mirror and duplicate. I can’t tell you the number of times I am racing to get a plot finished and forget to switch modes and then have to redo the work. It’s only a few seconds but it adds frustration to the process. Now that frustration is gone due to the program remembering my settings. Very nice.

The second thing about the visual design is the visual feedback the program gives specifically regarding instrument selection. Highlighting the objects and giving names and highlights to the area on an object as you pass over it is incredibly useful. While it took a little bit of time to get used to and be able to parse the visual language without it impeding workflow, I quickly became acclimated to it and very glad that it was there.

The basic Spotlight functionality is all there but no longer clustered in a single menu. As such I modified my standard lighting menu to include tools previously contained in the spotlight menu. These include convert to Symbol/Multicircuit, Assign Legend, Instrument Key, Refresh, and Number Instruments. In addition to the basic Spotlight functionality I used on these plots there looks to be quite a lot of additional material that I will be exploring in future posts.

The layout of the basic drafting window is very different from the version I was using before. All the class/layer menu information is still up top, but so too is the magnifying buttons and fit to page. While it took a little getting used to, the new layout is an improvement. Everything relating to visibility is in one place. Further, the addition of a classes/layers button is much improved over the older drop down menu item I previously had to contend with.

My biggest (and so far only) complaint is the changing of keyboard commands. While this is certainly something that can learned it is frustrating at the beginning. It should also be noted that Vectorworks keyboard commands are all fully customizable and editable(and I added back my align button). It just takes time. As I get deeper into the functionality of the program for later posts I will be approaching the software as though it were a wholly new technology for me as some of the changes are so massive that it might as well be.

I am looking forward to exploring the event planning suite of tools, new trussing, color/gobo libraries, and other new Spotlight tools as well.

As a drafting program to make a lightplot Vectorworks has maintained its edge as the industry standard setting the bar for what Computer Aided Design can do for the lighting and design community. I hope you’ll join me in future posts as I continue to explore this fantastic piece of software.
