Greg Gowans describes how to 'Fly a Tram'.
-One of the major scenic elements that we'll be flying will be the tram. The tram weighs 1.8 ton, and will fly off the southern stadium roof to the center of the stage. There's well over a year's worth of thought and effort that's gone into creating this one particular effect.
-We use some software that, it's commercial software. And they've done a very clever interface to it that it's very clever in its simplicity of what we have to do. You just draw what you want on the screen, and it works out where each winch has to be at a given moment.
The result of this visual animation on the screen is text files full of numbers. And the numbers just list where the winch needs to be every 200 milliseconds. At this point in time, I need to be here. 200 milliseconds later, I need to be here. And it just lists-- it's just a position, a number, like a millimeter's distance of how much cables come out of the drum off the winch.
-An integral part of the tram is actually some very, very large wings that you'll see. So that's another component of what we do in automation. We sort of animate things and automate things.
-So, I haven't seen it with the wings yet, so we'll see what it does. It might be a bit different because the weight will be there. We haven't had it with the wings on, so we'll see what happens later tonight, hopefully.
-It's quite interesting sitting in meetings with people who build bridges or build, you know, stadiums or light towers, and say, well, we want to fly a tram off the southern stadium roof. And they go, you what? So that's really kind of-- it's a fun part of what we do.
