• Sprite sheets, sprites, and sprite animations
• 2D movements
Remembering the past to build the future
Sometimes, the best way to go forwards is to go backwards. Science advances by
learning how things worked in the past then improving upon them. Video games are
quite the same in that they learn how things worked in the past, improve them, and
then double the explosions. Although the actual improvement of games is in the eyes
of the beholder, few can argue the extreme advancements that have been made in
game technology—both visually and in capability.
Today, we live in a world of hyper-advanced 3D graphics rendered by computers
that are powerful enough to rise against us and dominate our race. Some games even
challenge the player to compare their visuals against those in real life and determine
which is the game and which is real. New technological advancements now even
allow a full-body scan of an actor or actress that can then be applied as a texture to
a 3D model. The same model can also be built off a 3D scan of the same actor/actress
and placed in a real-time game environment. The result is a 3D character that, when
properly lit, can bypass the uncanny valley.
