At least in 3-space, they also have an interesting relationship with signed tetrahedral volumes, the scalar triple product, and Pluecker coordinates. I once got a published paper out of those connections ( http://www.cs.utah.edu

Yes, I've noticed their newer calculators now use the same style rubber or plastic keys as everyone else uses without that nice snap that the old had. I loved being able to key things in without looking. Also, the battery life was do

That's a bit of a running joke. It's funnier in the working draft PDFs of the standard, e.g.: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2014/n429...

As a fairly modern example, let me suggest "Physically Based Rendering" by Pharr and Humphreys [1]. It is a complete (and fairly large) book in the LP style. There are couple of sample chapters available online that you can view

Tracking is one thing that bothers me. The other are video ads that hijack my speakers and sap my bandwidth, pop over ads that hijack my screen focus, etc. Those are where I draw the line. I don't use explicit ad blockers, but I do r

I still like it for taking notes. Stuff seems to stick better in my mind when I take notes by hand compared to when I take notes by typing.

All good points. I'd also add: * Discarding data when finishing a bucket means that you have to produce final-quality pixels before moving on. Path tracing allows the renderer to produce an initial, crude pass over the pixels and the

Yikes! First company I ever worked for wasn't particularly flashy, but I did like that they had a "12-hour rule" to guard against that. The policy was that you wouldn't be expected back at work in fewer than 12 hours a

There's been some work on encoding video with triangles. See "Video Compression Using Data-Dependent Triangulations" ( http://www-home.htwg-konstanz.de/~umlauf/Papers/cgv08.pdf ) for example.

Yes, it's not exactly equivalent here but it's pretty close. Basically, Sobel kernels are analogous to the 1st derivative and the Laplacian is analogous to the 2nd. You'll also often see the Laplacian combined with a Gaussia

Garland and Heckbert had a nice algorithm for this sort of thing in their 1995 paper, "Fast Polygonal Approximation of Terrains and Height Fields." The paper is mainly devoted to height fields, obviously, but at the end they demo

I'll second your first point about hard copies. It's one thing to skim a PDF on the screen to see if it might be worth my time, but if I really want to grok a paper I'm marking up a hardcopy. This has also made me appreciati

You could perhaps implement std::equal_range() [0] that way. It behaves somewhat similarly to doing two slightly different binary searches (to find both the lower and upper bounds on where a key could be legally inserted into a sorted rang

I can't go into any specifics, but the general approach that most places use these days is to assign complete frames to each node on the renderfarm. The nodes are multi-core and threads divvy up the work of rendering the image in tile
