First I created a simple polygon plane in Maya, then connected a shader (it varies depending on the test) then plugged in a projection node into the colour so I could project my footage onto the plane. My first test I used a surface shader, so it did not require any lights. I then animated the camera but made sure that the projection always filled the screen. These tests I'm only uploading as YouTube videos since they are quite long and will not upload as GIFS.
I also experimented in After Effects using lights as well as other effects such as animating vignettes. I experimented with both spot lights and point lights. I found the spot light particularly difficult to control and I preferred the point light out of the two. However, one perk of doing it this way is that render times remain lower...the more lights I add in Maya the slower the renders will be (1 second per frame without lights vs 30 seconds with 3 area lights).
After seeing the previous five results, I think I liked #3 (Maya area lights) the most. I decided to return to this scene and adjust the position and scale of the area lights. I also wanted to try adding a vignette to the footage prior to bringing it into Maya - so the vignette effect is part of the projection. I hope that this will help further separate the projection screen from the viewer. This is currently rendering and the results will be posted tomorrow.
