pivotgraph - data visualization & visual design - information aesthetics

pivotgraph information aesthetics

a novel technique for visualizing & analyzing complex graph structures, such as of social networks. the method is designed specifically for graphs that are “multivariate,” i.e., where each node is associated with several attributes. unlike visualizations which
emphasize global graph topology, PivotGraph uses a simple grid-based approach to focus on the relationship between
node attributes & connections.
the graph is rolled up by two different data attributes (x & y-axis). the area of each circle is proportional to the size variable of the node. because of the grid structure of the graph layout, straight edges would almost always have serious occlusion problems. therefore, quadratic curved edges are drawn between nodes, with widths corresponding to their weights.

Liquid to to match the refractive index of a specific glass.

I'm trying to match the refractive index of a specific glass. What should I use?

Any of our Standard Series Liquids can be used to match the refractive index of nearly all glasses and plastics. For larger quantities, or a more exact refractive index match to your material, you should use one of our custom blended Immersion or Laser Liquids. We regularly manufacture liquids to match the refractive index of BK7, SF10, BaK, Fused Silica, PMMA, Polycarbonate, Polystyrene, and other glasses and plastics. Because many of our liquids are custom blended, we can ( most likely ) match the refractive index of your material at any wavelength and temperature. Please contact our technical services department to help determine which liquid is the best for your application.

OpenGL dome-correction libraries

Beta testers needed for OpenGL dome-correction libraries

Want to dome-enable your real-time OpenGL application? The OmniMap™ Geometry Correction Library API provides developers with an easy-to-integrate solution to make real-time OpenGL applications compatible with OmniFocus ™ projection systems. It takes advantage of the latest accelerated graphics hardware and OpenGL 2.0 extensions to increase performance over previous geometry correction software solutions.

We've been working hard to streamline and optimize the OmniMap API, and we're now releasing the public beta so you can kick the tires. If you're interested in participating in the beta program, please download OmniMap and let us know what you think. OmniMap is made available free of charge for application developers to dome-enable any OpenGL application.

This umbrella will wrap around the bride and groom, preventing her hair and veil from blowing even in driving rain and wind! Large enough for the bride, her train and the groom--and their guests can still see the happy couple, despite the conditions! Not only is the umbrella trimmed in white, but the center spoke and heavy hook handle are white as well. 60" Clear Dome Umbrella with White Trim $24.95 Quantity: Priority mail shipping charges are $9.00 for one, and $3.95 for each additional umbrella.

For those tho wish to make their portable think it's closed, even when it isn't, the solution is to place a magnet somewhere near the sensor. For Titanium Powerbook owners, the solution involves resting the magnet near the trackpad ^{2 4}.
