[Video for fun!](https://vimeo.com/169857945) SO! You wanted a breakdown of a no-budget shoot. Exactly... 20 March I was contacted to option what turned out to be a pretty cool project. A British team had written one of *those* scripts, but was sending it out to 10 filmmaking teams around the world. Each team would make their version of the script and show it at their local festivals, while the British team would cut together a version from all 11 projects. Edited for salt. I called a... I'm looking to buy a UST 4k projector with a 120" fixed-frame screen, for a dedicated dark room. A salesman at [my local AV company](https://listenup.com/) suggests the [Stewart Grayhawk G4](https://www.stewartfilmscreen.com/en/materials/grayhawk-g4) as an option for the screen. In researching screens, I see diagrams online suggesting that a [Fresnel](https://sc02.alicdn.com/kf/HTB1U9ovywHqK1RjSZFEq6AGMXXaC/225700846/HTB1U9ovywHqK1RjSZFEq6AGMXXaC.jpg) or [lenticular](https://www.projectorcentra...

Hi, Just having some trouble with a question about Fabry-Perot intereferometers. Here's the first part of the question: > Consider a beam of light undergoing multiple reflections in a Fabry-Perot cavity between two surfaces, both with reflectance R, and with no absorption. > a) What fraction of the original beam power entering the cavity is left in the beam inside the cavity after a number N of reflections? So my problem is incorporating N into my final answer. I've derived a general e...

If you want to see the original post with inline images see it [here](http://www.eastshade.com/creating-a-dynamic-sky-in-unity/). The sky is an important character in Eastshade. In addition to taking up a large portion of the screen at any given moment, it also gives players the sense that the game world has its own beating heart. While I knew I wanted to make the sky spectacular and dynamic, I also didn’t want to spend tons of performance or development time on it. While something like dynamic... Ok so myself and a large group are working on a sitcom for an in-school assignment and we need some help planning out our lighting.

I'm working on a homemade product that communicates with laser tag guns using infrared emitters and receivers. I want to make a new enclosure for the product but I need something transparent/translucent to put the emitters and receivers under. I found these lenses but I'm not really sure what they'll do to the light. http://www.3dlens.com/shop/proddetail.php?prod=Infrared-Fresnel-Lens-5131 Is there a diagram somewhere of how a lens like this affects light? The only ones I can find are for fla...

Fresnel light diagram. Disclaimer: I'm not interested in debating the science of climate change. If you don't believe in climate change please argue it elsewhere. Thanks! I have an idea for combating climate change, but it involves multiple engineering disciplines which puts most of the feasibility assessment of my idea outside of my expertise. I know myself well enough to know that I'm not cut-out to be an entrepreneur or leader of any sort. My hope is that posting the idea here might inspire some of my fellow engin... *"What has it got in its pocketses, eh Precious?"* - Gollum So apparently I missed my cake day. Here's a post to make up for it; I present to you my survival tin. There are many others like it but this one is mine. Parts sourced and kit assembled by yours truly. While a collection of small, fiddly items that rely on fine and complex motor skills to use might not be the best thing to have in a survival scenario, the advantage of the survival tin is that it goes in your pocket and stays there. I... My background is mostly in documentary where we've done either simple 3-point lighting set-ups for interviews or used natural light, for the first time I am confronted with a trickier studio-based lighting situation. I have a rough plan sketched out for lighting but a major concern is that I don't know WHAT lights specifically I need to rent in order to achieve these results. Here are a few photos of the studio room we will be using: https://imgur.com/a/eNDBndT Here is a diagram of my lighti... Is Magic Leap switching to MEMS LBS? One wonders because this latest “image display system” is all-inclusive of MEMS LBS and no scanning fiber. **US Patent Application 20190235252** **August 1, 2019** **METHOD AND SYSTEM FOR LARGE FIELD OF VIEW DISPLAY WITH SCANNING MIRROR HAVING OPTICAL POWER** **Abstract** An image display system can include a plurality of light sources configured to emit uncollimated light, and an eyepiece waveguide having an input port configured to receive beams of lig...
