4D Mesh Viewer [ROTATE THROUGH TIME]

[xXxMoNkEyMaNxXx]

I was going to make a 3D mesh viewer, but since images can store four values per pixel, I thought "Why not?"
I don't actually know if this would work if I had any properly formatted meshes, because the one I tried to make failed miserably. Instead, I use some images that I randomly generated instead of carefully plotted actual meshes. My format has one image for textures, one with information about the size and location of the textures, one for events (four-dimensional vertices), one to pair up textures and events to be considered the same object at different events & to interpolate between them, and finally one that describes a set of three event pairs and one texture pair that make up a triangular prism in four dimensions.
I am thinking about making a simpler 3D mesh viewer, because this got a bit out of hand.
I also made some great modular vector and matrix mini-libraries.

Controls:
E&Q = +&- w axis (time)
W&S = +&- z axis
Space&LShift = +&- y axis
D&A = +&- x axis

Y&H = Rotate XW axis
U&J = Rotate YW axis
I&K = Rotate ZW axis

Right click = rotate camera on x and y axis

When the program starts, hold the E key to change the time slice of the random 4D mesh in view (note that it does not exist at t=0).

weird, on my intel gfx card on Linux I see only a black screen, and when randomly hitting WASD keys after a while this error is thrown:

Mesa 8.0.5 implementation error: Failed to compile fragment shader: FS compile failed: no register to spill

On my NVidia card I see at least the coordinates in the upper left corner of the window but nothing else, no crash occurs.

I had the same experience, and then tried pressing the e key for a while when it first starts up, and I see some weird stuff show up. It does appear to move the way the controls suggest, but I have no idea what it's supposed to be.

looks quite trippy though

It's a bunch of random four dimensional triangular prisms, which when only shown at a certain timeslice, look like polygons

Most recent version.

wasd qe lshift space for axial translation,
right mouse & yuihjk for rotation on time and non-time axes.
numpad 123456 to rotate the model through time.
