• Creating zoom-pan video from a picture in Linux

  - by Pavel

  I would like to make a six second video using six images. Each second is sliding over one image from its top to its botom. Or some other motion effect – I would like to try several. I tried kdenlive Imagination Videoporama PhotoFilmStrip The first one has not enough settings (don't remember what exactly) and all those have rather poor quality – the resized picture is very "aliased" (like no quadratic filter was applied during resizing).

• How do I slow down a video generating new interpolated frames?

  - by Grzegorz Adam Hankiewicz

  I've used mencoder's speed parameter to generate a video which is played at half the speed. This basically means halving the framerate of the video. But I'm interested in software that could convert a 30fps video to another 30fps video with half the frames interpolated, maybe using the motion information stored in the video stream per se. I think this is called intra-frame interpolation, but I haven't found anything practical other than research papers. Any pointers to such software?

• BlackBerry 10 : sortie repoussée pour ne pas « compromettre le produit », le nouvel OS n'arrivera qu'en 2013

  Sortie repoussée pour BlackBerry 10 Pour ne pas « compromettre le produit », le nouvel OS n'arrivera qu'en 2013 Les résultats de Research In Motion, le constructeur canadien des BlackBerry, ne sont pas bons. Son chiffre d'affaires à chuté de 33 %, passant de 4.2 milliards de dollars au premier trimestre 2011 à moins de 3 milliards au premier trimestre 2012. Le tout pour une perte nette ajustée de 192 millions de dollars. Résultat, des réductions de postes sont prévus (5.000) et une politique agressive d'investissements est en cours (2.2 milliards de dollars). Les premiers effets se feraient sentir, mais sous la forme d'un frémissement. Le World Tour BlackBerr...

• Approximating walking physics via simpler sliding physics

  - by Dave

  I am modeling walking insects. I implement them as cuboids and use forces (including friction and drag), to control motion. However, the movement characteristics of this 'sliding box' physics don't match those due to a legged creature. For example, legged creatures near-instantly accelerate to their top speed; whereas applying a force to a box takes time to accelerate it. The applied force can be increased along with the counteracting drag, giving much quicker acceleration (via force) to a max speed (via drag). However, this also means the force that creatures can exert when pushing on other objects is increased. Does anyone know of any techniques using a physics engine to cheaply model walking creatures?

• Connect Microsoft Excel To SQL Azure Database

  A number of people have found my post about getting started with SQL Azure pretty useful. But, it's all worthless if it doesn't add up to user value. Database are like potential energy in physics-it's a promise that something could be put in motion. Users actually making decisions based on analysis is analogous to kinetic energy in physics. It's the fulfillment of the promise of potential energy. So what does this have to with Office 2010? In Excel 2010 we made it truly easy to connect to a SQL Azure...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• How to move a sprite automatically using a physicsHandler in Andengine?

  - by shailenTJ

  I use a DigitalOnScreenControl (knob with a four-directional arrow control) to move the entity and the entity which is bound to a physicsHandler. physicsHandler.setEntity(sprite); sprite.registerUpdateHandler(physicsHandler); From the DigitalOnScreenControl, I know which direction I want my sprite to move. Inside its overridden onControlChange function, I call a function animateSprite that checks which direction I chose. Based on the direction, I animate my sprite differently. PROBLEM: I want to automatically move the sprite to a specific location on the scene, say at coordinates (207, 305). My sprite is at (100, 305, which means it has to move down by 107 pixels. How do I tell the physicsHandler to move the sprite down by 107 pixels? My animateSprite method will take care of animating the sprite's downward motion. Thank you for your input!

• DIY Weather-Aware Umbrella Stand Signals Stormy Weather

  - by Jason Fitzpatrick

  This clever DIY project adds ambient weather notification to your umbrella stand–simply walk by it on your way out the door to get a subtle reminder to take your umbrella. The clever setup involves a hobby board, motion detection, and LEDS to a rather clever end. As you walk by the semi-translucent umbrella stand all of it is mounted in, it lights up to indicate the weather conditions. Blue indicates the forecast for the day shows no sign of rain, green indicates rain, and red indicates thunderstorms. Check out the above video to see the hardware involves and the stand in action; hit up the link below for the full build guide including code.

• Fade out Label / Button / Status Bar with GTK

  - by wolfv

  What is the easiest way to fade out and fade in elements in Python / GTK 3? Coming from webdevelopment, my initial take on this problem was to call c = widget.get_style_context(), c.remove_class('visible'), c.add_class('invisible') but that didn't work out (Do I have to call something like "redraw"?) I also added a transition to the GTK CSS. Thanks, Wolf EDIT: I might specify what I would like to achieve: I have this "statusbar" which is just a vertical container on my app (like in the screenshot on top of this page http://uberwriter.wolfvollprecht.de/). If the mouse is not moving, I want to fade all that stuff out (also to preserve computing power // no recalculation of word- and char count) and to minimize "distraction"). I already found the appropriate event to listen to (motion-notify-event), so now I only need to add a simple fade out and a timeout. If someone can point me to a solution, be it with clutter or cairo, I would be very happy.

• 3D rotation tool. How can I add simple extrusion?

  - by Gerve

  The 3D rotation tool is excellent but it only lets you rotate 2D objects, this means my object is wafer thin. Is there any way to add simple extrusion or depth to a symbol? I don't really want to use any 3rd party libraries like Away3D or Papervision, this is overkill for my simple 2D game. I only want to do this creating a couple motion tweens if possible. More Details: Below is what my symbol looks like (just with a bit more color). The symbol does a little 3D rotation and then flies away, it's just for something like a scoreboard within the app.

• Smooth animation in Cocos2d for iOS

  - by MrDatabase

  I move a simple CCSprite around the screen of an iOS device using this code: [self schedule:@selector(update:) interval:0.0167]; - (void) update:(ccTime) delta { CGPoint currPos = self.position; currPos.x += xVelocity; currPos.y += yVelocity; self.position = currPos; } This works however the animation is not smooth. How can I improve the smoothness of my animation? My scene is exceedingly simple (just has one full-screen CCSprite with a background image and a relatively small CCSprite that moves slowly). I've logged the ccTime delta and it's not consistent (it's almost always greater than my specified interval of 0.0167... sometimes up to a factor of 4x). I've considered tailoring the motion in the update method to the delta time (larger delta = larger movement etc). However given the simplicity of my scene it's seems there's a better way (and something basic that I'm probably missing).

• Let&rsquo;s try this again&hellip;

  - by svanvliet

  So it’s been a really long time since I consistently blogged on my previous ASP.NET blog (and, let’s be honest, it wasn’t that consistent to begin with!)  With the mainstream use of microblogging sites like Facebook and Twitter, I’ve been able to post more frequent updates (http://www.facebook.com/scott.vanvliet & http://twitter.com/scottvanvliet) but haven’t really authored any good content lately. Well, I decided it’s time for me to try again! I’ve relocated my blog from the ASP.NET weblogs site to my new home here at http://geekswithblogs.net (thanks @jjulian and @jalexander!)  I hope to be posting musings on here about Silverlight, motion graphics, digital media, digital supply chain, and even personal/fun stuff. Stay tuned!

• Weekend Project: Make Your Own Ferromagnetic Fluid

  - by Jason Fitzpatrick

  Experiments this simple and fun give you no reason to leave all science-based goofing off to the professionals: whip up a beaker of ferromagnetic fluid to capture magnetic waves in motion. The premise is simple: by combing a viscous liquid (in this case vegetable oil) with a magnetic powder (in this case MICR copy toner) and introducing a strong magnetic source (such as neodymium rare earth magnets), you can actually see the magnetic waves in physical space. It’s like the old magnetic filings on the table top trick, but in 3D. Check out the video above to see how you can mix up a batch of your own.

• Calculating 3D camera positions from a video

  - by Geotarget

  I need to calculate the 3D camera position and rotation for each frame in a given video. This is typically used for motion-tracking, and to insert 3D objects into a video. I'm currently using VideoTrace to calculate this for me, and I'm getting the data exported as a 3DS Maxscript file. However when I try to use the 3D camera rotations, I'm getting strange errors in my 3D calculations, as if there is an error with the 3x3 rotation matrices. Can you spot any error with the data itself? Or is it my other calculations that are erroneous? frame 1 rotation=(matrix3[-0.011938, 0.756018, -0.654442][-0.382040, -0.608284, -0.695727][-0.924068, 0.241718, 0.296091][0, 0, 0]).rotationpart position=[-0.767177, 0.308723, -0.232722] fov=57.352135 frame 2 rotation=(matrix3[-0.460922, -0.726580, -0.509541][-0.200163, 0.644491, -0.737947][ 0.864572, -0.238145, -0.442495][0, 0, 0]).rotationpart position=[-0.856630, 0.198654, -0.243853] fov=57.352135

• How can I apply different actions to different parts of a 2D character?

  - by Praveen Sharath

  I am developing a 2D platform game in Java. The player has a gun in his hand every time. He needs to walk and shoot with the gun(arrow keys for walk and X key to shoot). The walk cycle takes 6 frames and i am able to import the sprite sheet and animate the sequence when I press arrow key. But i need to add the gun motion. The player holds the gun upwards and when X key is pressed he brings it straight and shoots. How to implement the walk + shoot action?

  i have begun creating a very simple game engine and i am trying to work out how to create a time scale for the game.by time scale i mean some way of increasing and decreasing the speed of the game(not the fps) like creating a slow motion effect ... i have no idea how this could be accomplished so any help would be appreciated. if this help im using windows, Opengl and C++ in the game engine... How my engine is setup i have an update and draw function...update is called 25 times per second while display is called as much as possible.

• How can I factor momentum into my space sim?

  - by Josh Petite

  I am trying my hand at creating a simple 2d physics engine right now, and I'm running into some problems figuring out how to incorporate momentum into movement of a spaceship. If I am moving in a given direction at a certain velocity, I am able to currently update the position of my ship easily (Position += Direction * Velocity). However, if the ship rotates at all, and I recalculate the direction (based on the new angle the ship is facing), and accelerate in that direction, how can I take momentum into account to alter the "line" that the ship travels? Currently the ship changes direction instantaneously and continues at its current velocity in that new direction when I press the thrust button. I want it to be a more gradual turning motion so as to give the impression that the ship itself has some mass. If there is already a nice post on this topic I apologize, but nothing came up in my searches. Let me know if any more information is needed, but I'm hoping someone can easily tell me how I can throw mass * velocity into my game loop update.

• Where can I find Cinema4D for game development tutorials ?

  - by George Profenza

  Hi, I started to learn Cinema 4D. I've noticed it's really easy to use for motion graphics, but I want to use it for modeling for games/realtime 3d engines. Before I used 3dsmax and it was easy to estimate how a model would look/behave in a 3d engine. The two main things I did was displaying Polygon triangles and displaying the Polygon Count. I've found the Total Polygons tick in HUD settings in Cinema 4D, but I can't find any display mode that will show triangles. Is there there a way to display triangle faces/not quads in Cinema4D ? If so how ? There is a Triangulate function, but I'd rather not Triangulate/Untriangulate all the time, especially since it's converting back and forth between the two doesn't always produce the same result. I imagine I'm asking for old school techniques, but I plan to use these to make low poly models for web(canvas/webGL) and mobile.

• Simple 3D Physics engine as a part of graduation project [on hold]

  - by Eugene Kolesnikov

  I am working on my graduation project and one part of it is to simulate the motion of a rigid body in 3D space. I can use either already written physics engine or to write it myself. It's quite an interesting challenge for me, so I would like to do it myself. I am able to use either C++ or Java for programming (prefer C++). I am using Mac OS X and Debian 7. Could you suggest any guides or tutorials how to do it, can't find it anywhere... More precisely, I need a very simple engine, without collision detection, and many other things that I do not know, I just need to calculate the forces and move my body, depending on the resultant force. If you think that this task is still very difficult or there is no such tutorial, please suggest me some good and simple engine.
