Last night, I was at a used book store, which just happens to have a large section of RPG books. During which, I came across the AD&D Dungeoneer's Survival Guide (DSG). In the DSG, it had a small section that talked about perspective mapping.
What is perspective mapping you ask? Well to put it simply, it was way to show a 3D image in a 2D space. It allowed you see spaces like you never thought about them before. It could clearly show the relationship between a landing and the area above and below it. I always thought if you looked at a perspective map and then the standard orthographic maps (most maps used in gaming are basically orthographic projections from one side only), you would find a lot of additional ideas about where things are and where things are out.
So why didn't perspective mapping take off. After all, the DSG is pretty old? I think the main issue was how hard it was to generate. After all with a standard orthographic map, you you have to draw a simple grid, you really dont' care about height. I know in the DSG, they listed two way to make perspective maps. One was to use Tracing Paper and move it around the perspective graph paper that they had copies of in the DSG. The other was a method using a photo copier. In general, I don't think either method was very easy.
Of course that was then, what about now? It seems like with all the mapping software out there, someone would have created a package that does perspective mapping. Of course, I guess it depends on if anyone thinks that perspective mapping actually has a place. I personally don't know myself. While it's very cool, it seems like much the same information can be conveyed with additional orthographic maps of different sides.
So, I have few questions for you my gentle readers. Have you ever thought about using perspective maps? If so, did you? If not, why not? Lastly, do you think that perspective mapping has any place in gaming?
