Single Visualisation
It was now time to prepare for the first presentation. The presentation brief was simple, essentially : "What do you want to create?". I knew well what it was I wanted to create, a simple yet pretty music visualisation. I knew it would need two essential elements : Audio Analysis, and OpenGL Visuals. I had done a fair amount of work with audio analysis over the holidays, yet I had done next to nothing with OpenGL. I began researching the compatability between Processing, JOGL, OpenGL and Java - And what I would be capable of doing. I also did more research, focussing heavily on the works of Flight404, Toxi, and Victor Martins. I knew then the style of what I wanted to achieve, and the basic method on how to achieve it. Now it was just a matter of putting together a presentation good enough to impress my lecturers.
Putting the presentation aside, I was already planning the project. I knew that essentially it would be split into two parts - Audio Analysis, and Video/Graphics Rendering. I must have examined 15 different methods of audio analysis and experimented with 4 different audio libraries before deciding on one I thought was fitting. At this stage I focused mainly on the implementation of this audio analysis as a frequency spectrum. See the gallery below of screenshots of these two implementations.
This stage of design was quickly cut short however, as after the first presentation, I was forced to rethink my idea.
