A Layman’s Guide To Projection in Videogames

Oftentimes when a videogame has a skewed, overhead point of view, we call it isometric. That’s rarely the accurate term, though, and it’s not just pointless semantics.


Although Echochrome uses a single projection type, its gameplay is based on constantly rotating and morphing its 3D structures. With each new view, the physical architecture of the level changes to reflect what the player sees on the screen.

Projection basically means taking a three dimensional object and displaying it on a 2D plane (i.e., a screen). There are various ways of accomplishing this, and each technique has a deep impact on a game’s look and mechanics. The advent of 3D games and free-floating cameras somewhat lessened this role, but being aware of the pros and cons of each projection type is still applicable to both 2D and 3D titles.

So what exactly are these projection types? Well, let’s take a look:

Orange Box Designer Commentary

Valve first tried out designer commentary with the Lost Coast standalone demo. Apparently it was such a big success that they decided to do the same for all the games in the Orange Box.

Now Valve is a group of some very, very smart people, and it shows.


Escape from City 17 at the end of Half-Life: Episode One.

Generic behind-the-scenes specials tend to tell the same old story: the development cycle was hectic, but the team eventually persevered and released a great product (even if it was a little flawed and missing some features). In between all that you might come across an interesting tid-bit or two, but don’t expect any mind blowing revelations.

The commentary on the Orange Box, though, is full of pure-gold nuggets. In fact, playing through its four commentary-enabled titles will probably teach you more about various aspects of videogame production than any game design book. If you haven’t checked it out but are in any way interested in videogame design, I urge you to do so now.

Here are just a few segments I picked out:

The Greatest Collectible Of All Time


One of the famous coin arrows in Super Mario World.

In-game collectibles are a staple of platformers and play a big part in various videogame genres. They help to fill out maps, provide points bonuses and aid the player in overcoming the game’s challenges. They also flesh out the setting, sometimes even being used as part of its architecture, e.g., the coin-arrows in the various Super Mario games.


Apparently all clocks in Final Fantasy VI are secretly powered by elixirs.

Collectibles seem to speak to the kleptomaniac side of our personality, encouraging us to take all that we see. In console RPGs, it’s common to break into people’s homes, rummage through their belongings, and generally pillage the entire world that you’re trying to save.

And why not, really? After all, as players we want to be rewarded for exploring. It’d be awfully dull going from one empty room to another, so letting us interact with the game as if it were an episode of Supermarket Sweep might not be such a bad idea.
