• Convet long/lat to pixel x/y on a given picure.

  - by kalininew

  I have a city "map" (for example - Moscow). She in accuracy repeats the contours the given city in google maps (that is it is copied from google maps and it is a little processed, but the sense remained the same). Also I have object co-ordinates in a city (in co-ordinates of google). Problem: how to translate google co-ordinates to the…

• How could I safely fix my walking "dead pixel" bug?

  - by Cawas

  I need suggestions. I've got a live little bug inside my macbook pro screen for 2 days now. I've tried to film it using my iPhone, but it ain't that good. :( Should I try to open it? o_O C'mon, looking for ideas here! :) edit: Here's an alike video. It's not moving anymore for now... I hope it isn't dead! Right when I've…

• Best approach to depth streaming via existing codec

  - by Kevin

  I'm working on a development system (and game) intended for games set mostly in static third-person views. We produce our scenery by CG and photographic techniques. Our background art is rendered off-line by a production-grade renderer. To allow the runtime imagery to properly interact with the background art, I wrote a…

• Zoom image to pixel level

  - by zaf

  For an art project, one of the things I'll be doing is zooming in on an image to a particular pixel. I've been rubbing my chin and would love some advice on how to proceed. Here are the input parameters: Screen: sw - screen width sh - screen height Image: iw - image width ih - image height Pixel: px - x position of…

• convert list of relative widths to pixel widths

  - by mkoryak

  This is a code review question more then anything. I have the following problem: Given a list of relative widths (no unit whatsoever, just all relative to each other), generate a list of pixel widths so that these pixel widths have the same proportions as the original list. input: list of proportions, total pixel…

• using heightmap to simulate 3d in an isometric 2d game

  - by VaTTeRGeR

  I saw a video of an 2.5d engine that used heightmaps to do zbuffering. Is this hard to do? I have more or less no idea of Opengl(lwjgl) and that stuff. I could imagine, that you compare each pixel and its depthmap to the depthmap of the already drawn background to determine if it gets drawn or not. Are there any…

• How do I make one pixel change its color in HTML?

  - by brilliant

  Hello, let's say I have some given coordinates x and y for a pixel, how could I make it red (keeping everything else on the page just white) in HTML? Is it possible in HTML?

• how to get the colors on the screen better then get pixel? (c++)

  - by blood

  i made a program that uses the colors of pixels from the screen but getpixel is slow so is there a better way to find the color of pixels. i don't care if i get the full screen or one pixel at a time but the main thing is speed.

• how to set/get pixel on a texture in OpenGL ES on iPhone?

  - by unknownthreat

  I am trying to Google for what I've mentioned in the title, but somehow I couldn't find it. This should not be that hard, should it? What I am looking for is a way to gain access to an OpenGL ES texture on iPhone, and a way to get/set pixel with it. What are the OpenGL ES functions I am looking for?

• scorecardresearch dot com: weird tracking pixel

  - by Bobby Jack

  I'm seeing very weird behaviour in relation to this domain and a tracking image. On a specific page on our site, I'm seeing a script that's being added dynamically, apparently via flash (I wasn't even aware that flash could alter the DOM ...) That script is located at: http://scorecardresearch.com/beacon.js When…

• Per Pixel Collision Detection

  - by CJ Cohorst

  Just a quick question, I have this collision detection code: public bool PerPixelCollision(Player player, Game1 dog) { Matrix atob = player.Transform * Matrix.Invert(dog.Transform); Vector2 stepX = Vector2.TransformNormal(Vector2.UnitX, atob); Vector2 stepY = Vector2.TransformNormal(Vector2.UnitY,…

• Algorithmically generating neon layers on pixel grid

  - by user190929

  In an attempt at a screensaver I am making, I am a fan of neo-like graphics, which, of course, look great against a black background. As I understand it, neon, graphically speaking, is essentially a gradient of a color, brightest in the center, and gets darker proceeding outward. Although, more accurate is…

• 2D Pixel/sprite game in unity? [on hold]

  - by acidzombie24

  Hi I'm an absolute newbie in unity. In the past I was told unity is terrible for 2d games so I look away after looking at it for a few days. I don't remember if this was right before unity4 came out or after. I hear unity is fairly good at 2d now. I tried googling for tutorials but I'm doing it wrong. I…

• Pixel alignment algorithm

  - by user42325

  I have a set of square blocks, I want to draw them in a window. I am sure the coordinates calculation is correct. But on the screen, some squares' edge overlap with other, some are not. I remember the problem is caused by accuracy of pixels. I remember there's a specific topic related to this kind of…

• GLSL per pixel lighting with custom light type

  - by Justin

  Ok, I am having a big problem here. I just got into GLSL yesterday, so the code will be terrible, I'm sure. Basically, I am attempting to make a light that can be passed into the fragment shader (for learning purposes). I have four input values: one for the position of the light, one for the color,…

• Silverlight Pixel Shader resource "not found"; what should the URI be?

  - by Grank

  So I've written and compiled an HLSL pixel shader with Shazzam, placed the resulting .ps file in my project, and am trying to instantiate it. No matter what URI I put, Blend tells me that the resource can't be found whenever I try to view any xaml designer, and Visual Studio just shows me a…

• What could cause a pixel shader to paint outside the lines of the vertex shader output?

  - by Rei Miyasaka

  From what I understand, the pixels that a pixel shader operates on are specified implicitly by the SV_POSITION output (in DirectX) of the vertex shader. What then could cause a pixel shader to render in the middle of nowhere? I used the new Visual Studio 2012 graphics debugger to visualize…

• Getting Greyscale pixel value from RGB colourspace in Java using BufferedImage

  Anyone know of a simple way of converting the RGBint value returned from <BufferedImage> getRGB(i,j) into a greyscale value? I was going to simply average the RGB values by breaking them up using this; int alpha = (pixel >> 24) & 0xff; int red = (pixel >> 16) &…

  I have an integer array of RGB pixels that looks something like: pixels[0] = <rgb-value of pixel(0,0)> pixels[1] = <rgb-value of pixel(1,0)> pixels[2] = <rgb-value of pixel(2,0)> pixels[3] = <rgb-value of pixel(0,1)> ...etc... And I'm trying to create a…

• Drawing single pixel in Quartz

  - by wwrob

  I have an array of CGPoints, and I'd like to fill the whole screen with colours, the colour of each pixel depending on the total distance to each of the points in the array. The natural way to do this is to, for each pixel, compute the total distance, and turn that into a colour.…
