Rendering trickery is part of the process for the digital, online graphic novel — The Lightstream Chronicles

This week, two of the stars of our web comic, graphic novel continue chatting it up in the public security command center at Police HQ. I will let the conversation speak for itself and focus today’s comments on the challenge of rendering these control room scenes.

As I have stated before, everything is “shot” on location. That means that Kristin and Toei are on in virtual space, in a control room location, atop the same police headquarters featured on page 41 with a view of the built city of Hong Kong 2 that has been featured on pages previously. (The latest being chapter 2 prologue pages ix2-x2). Hence, when the camera is framing our cast the view is exactly what is “outside” the windows, or with them “in the room”. One would logically think, then, after all this “building” that it would be a simple matter of lighting and “shooting”. Alas, it’s not so simple. And the problem is focus. Using a real camera, in a situation like this would most likely yield a background out of focus so that we could capture crisp focus on our characters. Unfortunately, in Autodesk Maya, incorporating the rendering algorithms to calculate depth-of-field into all of these renderings would have increased rendering time astronomically, and probably not yielded a realistic look when it was all finished — if it ever finished.

I wanted the reflections in the glass to be fairly crisp, but the buildings that were far off in the distance to be more out-of-focus. All this required separate renderings. One for our subjects, another for the glass, and a third for the cityscape. Then the appropriate amount of blur was applied to each layer in Photoshop and composited into one single image with a believable depth-of-field. All part of the process of making The Lightstream Chronicles as engaging and visually interesting as possible.
