Another dynamic perspective demonstration created using Processing. I rebuilt a 3D version stage of the classic arcade game Contra, which was originally developed and released by Konami in 1987. The technology (POV, or Perspective of Viewer tracking) implemented using Vicon System is identical to the one I used in my previous demo Portal 2.0 (vimeo.com/101481415). To create all the animated sequences in the game demo, I partially used the original Contra sprites (nes-snes-sprites.com/contra.html). Also, for audio part of the game, the music in Contra (1987) (timewarpgamer.com/features/music_contra.html) and the sound effects in Super C (1988) (newgrounds.com/portal/view/488329) were selected and combined into a hybrid.
