this has nothing to do with the fourth dimension..

Basically, what I'm asking is, if a person somehow ended up in a four-dimensional world, with a four-dimensional body capable of moving in all four dimensions and senses capable of seeing in 4 dimensions, would their brain be capable of adapting to navigating and sensing this world, or not?

If 3 dimensions can be simulated, why not 4? And if you were to use 3-d technology, like stereoscopic glasses for instance, you would be even better equipped to simulate the 4th dimension. To a computer, 4-d would not be that hard to render. The hard part would be conceptualizing how the visualization should be done. I think it would be very hard for most people to adapt to 4d, it might be something that only young kids who grow up learning it can handle. I know people who have been blind from birth who get cornea transplants have a very hard time adapting because their visual development never happened. I wrote a simple game recently that deals with multi-dimensional space, but you have to cycle which dimensions you are viewing. Needless to say, it gets confusing, but 4-d is almost OK.

A computer would need to calculate a huge amount of data to simulate the 4th dimension possibly more than could fit in its volume.
On topic, it depends what kind of graphics you're doing.
As well as an extra coordinate for each point, you'd have a lot more simplices to be stored and drawn (just compare some of the 4D shapes to their 3D equivalents).

Says you.
I can personally visualize some four-dimensional objects, but not everything. Some people here have reportedly had dreams in higher dimensions.[...]

solid / length = surface (N-1); surface / time = margin (N-2 space),
Since N=4, a blade is 2d.

This is something I've been pondering about the past couple of days.
I know computer technology isn't quite up to the task yet.
Hower, suppose that sometime in the near future, people could directly link their brains to a computer-generated virtual environment and that virtual environment was 4-dimensional.
In this virtual environment, the person connected to the computer would have access to a 4-dimensional body capable of 4-dimensional locomotion and 3d-retinas for eyes.
Would a human brain be capable of adapting to perceiving and moving around in this virtual environment, or are our brains so hard-wired to navigating and perceiving a 3d-environment that we would hopelessly confused.
To put it another way, let's say a human brain got somehow transplanted into the body of a 4D creature, would that person and their brain be able to adapt and learn, or not?
For example, there are cases where people who have been blind since a very early age have had their sight restored, but unable to comprehend or only partially comprehend what they are seeing.
