Dense Image Space description

Dense Image Space (DIS) description

    This is a skeleton description of the construction and display geometry of a spatially dense array of images (dense image space, or DIS), which retains and utilizizes all overlapping image data. Superficially a DIS is similar to stitching multiple images into a panorama.

    With a panorama:

Laptop Macgyvering

Thanks for the email on the spam bots Mark. They're insidious. I turned off all anonymous posting. I will post more on general enzymind stuff later.

Web predictions

 TED Video which speculates on the next 5000 days of the web. Infers connections between web and brain strucutre interconnectivity.

Also a nice fluid dynamics video of experiments being done on the interntational space station in micro gravity.

Alan Kay and childhood education

I've been reading a lot of material developed by Alan Kay (e.g. his writings), and others who have been influenced by Kay's vision of what operating systems and software should look like to create a revolution in the way people, in particular children, learn.

Meek Geeks

David Brooks wrote a spot-on opinion column in the NY Times today, "The Alpha Geeks ". Brooks is an influential journalist, button-down political pundit, and cultural commentator.

Editing of a polygonal mesh

Once a polygonal mesh is extracted from volumetric data, any imperfections need to be resolved and validated. These imperfections might includes holes (each surface needs to be topologically closed), intersecting polygons and singularities. I won't know how much editing will be needed before I try the surface extraction with a few sets of parameters.

It looks like MeshLab might be a good surface editing tool:

Volume to surface data

The process of surface extraction will likely need to be done several times to get the desired surface qualities -- sulcal features that are deep, but not too deep, with a manageable number of polygon flaws.

 

Virtual graffiti

I've been thinking about a combinatorial problem related to square tilings -- how does one arrange n terms (or symbols/motifs) such that all combinations of neighbors occur. This led to a square tiling that would look good on a large scale, so I did a photo manipulation on a brick wall:
