  1. Re:Wrong problem anyone? on The Hobbit Filming at 48fps · · Score: 1

    How would you render any artificially-produced images? From titles, lower thirds, and picture-in-picture to all out visual effects and compositing, digital computers have a small problem with infinity that would make the above workflow just about impossible. How, for example, could you pull a greenscreen matte if there's no single image to work from?

    Also, it sounds suspiciously like MJPEG, which sucks.

  2. Re:Wrong problem anyone? on The Hobbit Filming at 48fps · · Score: 1

    When (real, analog, photochemical) film is projected in a theater, the revolving shutter has two cutouts so that each frame is displayed twice. This has always been explained to me as a way to both boost the brightness of the picture and to help with persistence of vision and the illusion of motion - 24fps is about the lowest you can go with a straight face, and was chosen to minimize film stock costs.

    I imagine that by shooting and projecting at 48fps, Jackson intends to display the image for only on eye on the screen at one time, displaying 24fps to each eye but staggered by 1/48th of a second - sort of like an interlaced image on an SD television, but in time instead of raster lines. So motion blur and other cues for the "film look" will still be present.

    Whether this will work, I have no idea, but I'm willing to believe that he and his cadre of top-of-the-field visual effects artists at Weta have an idea informed by a fair amount of research and testing.

    Got any back-of-the-envelope numbers for (total area of unshaded south-exposed residential roofs in the US) * (efficiency of solar shingles)? Along with cost estimates for that approach (as implemented through building codes) versus 40-50 new nuke plants?

    The repeal of Glass-Steagall passed the house 343-86 and senate 55-44 post-Monica Lewinski. A veto would have been an empty gesture. Besides, ignoring Reagan and Bush I's deregulation (Silverado Savings and Loan, anyone?) is disingenuous.

  9. Re:Hydrogen not even used universally in rockets on Artificial Leaf Could Provide Cheap Energy · · Score: 1

    Given that power generation currently involves handling materials like enriched uranium, plutonium, and fly ash in quantity, I think it could be OK. The "hydrogen economy" of shipping H2 everywhere for point-of-use consumption is a joke, but as onsite energy storage for a solar array (where you could isolate the tanks with a large empty area of land) I could see it working.

    indicates it was the Afghan policemen who took drugs and paid for the young dancing boys, not the contractors. In fact, as written, it was the contractors who trained the police to take drugs and hire dancing boys.

    So you're suggesting that the newspaper's editors misunderstood their own article when giving it the headline

    "Foreign contractors hired Afghan 'dancing boys', WikiLeaks cable reveals?

    This is also not the first time DynCorp employees have been caught engaging in child sex slavery. And these "contractors" are performing functions such as training Afghan police and guarding US embassies that historically have been done by soldiers.

    Yes, there is a long-standing tradition of organized child rape in Afghan culture. And we should be having nothing at all to do with it, and we should be arresting and throwing the book at the contractors that are.

    For design rather than drafting, more or less everyone I interact with is using SketchUp (Windows & Mac). I even see SketchUp previsualizations on many of those remodeling shows on DIY network. And now that 3ds max can open .SKP directly, and VRay and Maxwell are available for SketchUp, you don't really need the Pro version unless you're taking the SKP into Revit or AutoCAD for drafting.

    It's also about the only relevant architectural design/3D software ADSK couldn't buy out with the change in its couch - very insightful/awesome of Google to buy them first.
