I think there is no standard package that can that stuff for you.
You have to reinvent the wheel like all those 4d applet/raytracing writers out there, but this time in maple.
First think about your used projection (perspective, parallel, orthogonal, etc). From 4d to 3d and from 3d to 2d.
If you simply want to make a wirefrime model, you project the 5 points in 4d to 2d and then draw a line between each two of them.
4d Rotation algorithm can you find somewhere here on the forum (though I dont know how to write interactive maplets).
Its all a lot of effort, if you have specific questions, turn back to the forum
@Pwrong come on, you know the maths of it!!!
