I've been using Gears file upload and server side crop&resize a lot recently and it's turned out quite nice, hopefully sometime soon Chromium release a working HTML5 File API so it's not tied to a few browsers and I get image preview back in the open file dialog in Ubuntu. Click here for the full 1097x678 image. Every page has a admin icon that accesses page specific data, the goal is overlaying the administration on the end user site to reduce duplication of effort and to concentrate the navigation on the end user. This site however is a simple example as it's structure is rather small. The icon only appears for users logged in, via OpenAuth, to the company domain.  Click here for the full 1098x682 image. The administration is all implemented in jQuery UI dialogs and tabs. Help links redirect to Google Sites so that end-users can also update the content with notes.  Click here for the full 1097x681 image. Uploading an image brings up a standard dialog inspired by Google, although the list of sources is limited in this example it can extend as per requirements to link to other resources. Upload progress is displayed in the dialog using the Gears API feedback.  Click here for the full 1098x681 image. Crop&resize occurs on a 512x512 scaled version of the uploaded image so you don't have to re-download the entire source image, important with high resolution DSLR photos. jQuery changed the resize icon in recent version and doesn't work as well as it used to, as shown here,  Click here for the full 677x536 image.  Click here for the full 1096x683 image. Resize&crop complete the browser downloads a thumbnail version and the user can do other work if available. Closing the dialog refreshes the underlying page to reflect data content updates.  Click here for the full 1097x682 image.

Avenging Dentist posted:Stealing more poo poo from the fractal flame algorithm (log scaling and colors): I know I've said this already, but that is awesome! On a related note, can you think of any way to shoehorn the fractal flame colouring algorithm into the original regular polygon chaos game algorithm? I tried colouring it a simple gradient map based on how far each new point is from the previous but the results look terrible. The fractal flame scheme depends on there being multiple different functions for generating a new point and colouring it based on function used to generate it. Do you think it might work to colour the points generated from a standard chaos game by some category, like which vertex they were drawn towards maybe?

tripwire posted:On a related note, can you think of any way to shoehorn the fractal flame colouring algorithm into the original regular polygon chaos game algorithm? Instead of just working with random vertices and a fraction for interpolating between your points, use a random function. It's easy to create functions that do the same thing as the polygonal version. From Wikipedia: quote:The term ["chaos game"] has been generalized to refer to a method of generating the attractor, or the fixed point, of any iterated function system (IFS). Starting with any point x0, successive iterations are formed as xk+1 = fr(xk), where fr is a member of the given IFS randomly selected for each iteration. tripwire posted:Do you think it might work to colour the points generated from a standard chaos game by some category, like which vertex they were drawn towards maybe? This is exactly the coloration scheme that fractal flames use. What I do (again stolen from fractal flame stuff since I haven't gotten around to adding my own weird poo poo) is take the average of the current color and the new color (based on which function I picked). Technically, I'm not doing it 100% right yet, since the starting color is black, and it really should be "nothing", but that'll get dominated by the sheer repetitiveness of the algorithm.

It's probably more-or-less trivially parallelizable except for contention with the output buffer (which may not be an issue anyway if you're good with lockless programming - I could probably do a grayscale version locklessly), but you can just operate on multiple buffers and merge when you're done. I think a better question is why you are appealing to an "authority" (i.e. the SA forums) instead of edifying yourself by trying to devise a solution on your own, especially when you seem to have experience with GPGPU. Or is this just a case of "When the only buzzword you have is 'GPU', everything is a potentially parallelizable problem"?

Turns out encoding horizon levels using a radial Fourier transform lets you do self-shadowing textures extremely cheaply: Click here for the full 789x530 image. Well, if 5 bytes of storage per texel is cheap, but I guess you don't have to use it for everything so whatever. I'm sure someone else has invented this already.  edit: Posted article describing it: http://codedeposit.blogspot.com/2010/02/self-texturing-shadows-using-radial.html OneEightHundred fucked around with this message at 06:52 on Feb 11, 2010 |

The horizon level thing for self-shadowing was actually originally intended for models to overcome some limitations of PRT (i.e. PRT sucks with normalmapping) and hopefully develop a cheap way of emulating self-shadowing without being forced to use high-resolution shadowmaps. Fortunately, it works okay for that too: Done the same way, except per-vertex. It's actually reasonably fast to calculate since you can determine the horizon level of a triangle by intersecting each edge with a plane coplanar with the vertex normal and a radial direction. (Grayscale because my model viewer doesn't really have a way to toggle scene parameters at the moment). OneEightHundred fucked around with this message at 05:42 on Feb 13, 2010 |

 I'm making a 3d space trading game atm, I want to make most of the assets procedural so that I don't have to worry to much about art and stuff. Here is my first pass at a planet shader / procedural cloud generation. Things still left to do: * Make the terrain texture procedural * Multiple cloud layers * Randomly generate planets based on heuristics I'll post the results when I'm done!

Scaevolus posted:Are you using Perlin or Simplex noise for the clouds? Nothing so fancy. I am generating 4 32x32 noise maps (math.random style). Scaling map 1 up to 512x512, map 2 up to 256x256 (tile by two), map 3 up to 128x128 (tile by 4), map 4 up to 64x64 (tile by 8). The upscale on the GPU with linear sampling does some minor blurring on the texture. I then perform a gaussian noise pass each texture. I then combine the textures with each texture contributing a different amount to the final image (the larger granularity contributes more then lower granularity). I then perform a tiling pass to make the clouds tileable. All this apart from generating the 32x3x noise maps is done on the GPU. At render time I have a function that (using exp) that modifies how cloudy the clouds look.

I decided to make my first GUI program in C++, more to get a handle on the basics of GUI programming than any utilitarian purpose. I decided to go with Qt for this, and basically all it does is take a file name, lets you paste a precomputed MD5 string, and it makes an .md5 file for it. I've pretty much got it finished now, but I can't seem to figure out how to compile it so that all dependencies are contained within the .exe to make it portable, instead of having to drop all its dependant DLLs in the executable folder. I tried to follow this guide, but there was an error during compilation, which ended up totally loving up the Qt library, so I couldn't compile any programs at all. Could someone point me in the right direction? Cosmopolitan fucked around with this message at 12:23 on Feb 15, 2010 |

Ah it was you doing the Repton LPs. Looking forward to this, the 2D Repton clone has kind of disappeared as a genre unless you count stuff like Mr Robot but it seems like with iPhones it ought to come back pretty soon. I too am doing something similar but am currently stripping out all the vestiges of wxWindows from my engine.

I'm just starting to poke around Matlab, but haven't really found anything beyond simple polynomial fitting. The canonical method I was taught seen involves radial basis functions as finite elements - the idea is the same but a specific basis is chosen that remains well-conditioned in higher dimensions, a property that the monomial basis doesn't have. In one of my classes last term, I took the Radiohead House of Cards dataset, stripped out most of the datapoints, and reinterpolated them using a thin plate spline basis, and reanimated a couple of seconds. It was fun and interesting I've never played around with Fourier functions for surface fitting, though, so let us know if you discover anything useful there

Some time ago I made the following realizations:
To speed up the vocabulary-learning process, I'm finishing up a Chrome extension that uses the Google Translate API to switch random words on all the web pages I visit into an arbitrary foreign language. The theory is that sooner or later I'll pick up their meaning from context. Doesn't take care of the whole grammar problem, but it's better than nothing. Here it is in Death-to-America mode:  Click here for the full 1278x750 image. French mode.

This is an amazing idea - I love the idea of learning vocab in the context of your own language. Might not be so effective for grammar, but still could be useful. I suck at school taught languages, but I might just have to try this.

I have no idea about the flash card thing; not really sure how restrictive the Chrome sandbox is when it comes to messing with files in other programs, but it might be possible to add at some point. The page load doesn't seem to take any longer, but the words don't actually change until after about half a second. I guess this could be kind of jarring if you're already reading by then. Of course, it'll depend on how long it takes you to ping a Google translate server. I'll probably post it online somewhere later this week. I just need to tart up the settings page.

You're likely to learn a few things wrong with that, mainly due to phrase structure and loss of meaning from the context, different idioms and gender. Only looking at your wiki example in French (https://wi.somethingawful.com/aa/aa27b0d1550d76e6ea36560cd66249a93c619e11.png) "S'il vous plaît vote" -> "Votez, s'il vous plaît" "dans 1859" -> "En 1859" "le ... dispute" -> "la dispute ..." "là bas" -> "là-bas" "and environ follows the blue line" -> "and approximativement follows the blue line" What I find problematic with your tool is that it works well a bunch of times, and then fails in some cases. There's no way to tell what is right or wrong except by already knowing the right answer. That's the problem with machine translation. Finding literal translations made by humans is really what would be the best to learn from. Otherwise, that's a pretty nifty tool. I'm thinking I might like to use it to re-learn Spanish if I had a dictionary on hand to double-check the meanings.

What if that translator thing only changed nouns and simple verbs? Having it translate words like "it" and "of" is going to be useless, but translating "jumping" and "fridge" would be cool.
