So we warped the image in Madmapper to stretch it back into the correct alignment. We also didn't have the required space on stage to center the projectors in front of each wall. For the Immerse project, we had to mount our projectors higher above the projection surface than they were designed to be. Two parts of an image can be picked up from the input side of Madmapper, then "wrapped" around the corner of the cube so that the image is nice and square from the viewers perspective. For example: Trying to project an image onto two adjoining sides of a cube. In some cases, that can't happen so we can use Madmapper to correct for that. The first is geometry adjustments- In a perfect world, we would always have our projectors pointed directly and squarely at the surface that we're trying to project on. Madmapper is software that allows the user to do several things to the output of a projector. Recommended System Requirements include a Nvidia or ATI graphics card and 4+ GB of RAM. The minimum system requirements are a Mac computer with an Intel Processor (pretty much every Mac made at this point,) running OS X 10.10 or later. It's designed to process and render all of its video content on your Mac's graphics processing unit. All of these options present the user with an infinite sea of ways to control their video rig. There are even plug-ins to enable the use of Nintendo Wiimotes. Most of VDMX's functions like video clip triggers, cross faders, speed control parameters, screen placement can all be assigned to either keys on your Mac's keyboard, a MIDI Controller, or OSC based controller. If you're familiar with Ableton's Live software for audio, in the same way, that you can work in real-time, triggering sound clips and samples, you can do the same thing with VDMX. You can almost do anything that you would do in a video editor but in real time. You can load video clips into it much like a video sampler, add many different effects such as blurs, color swaps, flips, cropping, masking, speed changes, reverses, kaleidoscopes, all sorts of effects and plug-ins. Think of VDMX as a non-linear video playback and manipulation system. It would be like calling Mount Rushmore a statue, or the Grand Canyon a riverbed. In my humble opinion, calling VDMX VJ software is an understatement. In fact, their tagline is "Professional VJ Software." Think of a VJ as a DJ, but rather than using records, discs, or now audio files, a VJ would use video files. Vidvox's VDMX software is a Mac-based media/video server software. I became pretty smitten with it at that point. I was searching the internet for more information about it one day and found out one of my favorite musicians, Tycho uses it as well. They would mask out areas on the stage they didn't want to show video on, or use it to highlight specific things during their worship sets. The church he was attending at the time was using it to feed content into a projector aimed at their upstage wall. I started tinkering with VDMX several years ago after hearing about it from my good friend Josh Orton.
