    Well, my Canon HV20 1080P video camera was less than $500, and does a smashing job on laser and projected visual footage. I love living in the future

    Cool

    That's just one frame, right? I downloaded it, but I can't tell a whole lot with this viewer. I'll need to try to load it up into LD2000 later and have a look, but it appears to be a 2D frame, right? Still, you're on the right track... You should be able to extrude it into 3D.

    Isn't the whole point of a tesseract that it is a 4D image ?

    To make a proper one, you should make it in 4D, not mimic it in 3D.

    WELL the idea is this..
    A tesseract can NOT exist in in 3d space. its like the shadow of a 4d object in 3d space.
    please watch carl sagan explain..

    WELL if you want it as a laser display image it does NOT exist in 3D either, it is a projection in 2D.

    The interesting animation that you are after is achieved by rotating in 4D not by muddling around in 3D.

    Did you know you can draw a tesseract without blanking lines....

    yeah i saw some kid do it on youtube..

    the animation i want is 3d. its represented (or displayed) as 2d but ILDA is object oriented 3d space (or as james would say '16 bit integer space')

    soo you can recreate the 3d projection of what the 4d object rotating would look like, just as you can draw the 2d shadow of what a 3d object would look like

    OK, who is showing that holier than thou attitude now?

    You are trying to sound like "oh I've mastered this" but in fact you are learning from Youtube (rather silly show actually) instead of reading the thesis I pointed out earlier.

    The only point to this exercise is if you can bend your mind around a fourth spatial dimension, not simply redraw animations made by others. If you had grasped the true form of a tesseract you would have discovered yourself that you don't need blanking lines to draw it. This is an optimization that every laserist should see immediately.
