I'm in dire need of help. I've had UDK for several months but continuously run into problems.
In a nutshell I'm trying to make my own video game using UDK as the game engine. In 3ds max 2013 I have created two entire houses that I've been trying to import into UDK to then be able to walk around in and eventually code events and all that.
My main issue right now is I'm trying to import the front lawn (literally a near flat plane) with a custom collision I made using the video tutorial here - http://www.3dmotive.com/training/fre...k/?follow=true
I know this tutorial is old but I thought it would work - it won't for me - the collision model doesn't register and it seems the collision box I made in 3ds enveloped the actual plane.
So I'm looking for as much help as I can get! Is anyone has suggestions on this specifically you are deemed epic and awesome, and those who have tips or tutorials or whatever that is recent (for the July 2012 UDK beta release) I will love you forever.
Please help a newbie out!
In order to import a mesh into UDK it must be in ASE file format.
Is it in the proper format? if so check your export settings and play with those.
UDK has an in engine collision generator as well which is simple to use and a useful tool.
You can use it by going to the static mesh properties toggle on collision and generate new collision.
(the link you provided does not work).

I've been doing some work in VB.Net with Directshow over the past 3-4 weeks. I'm creating an application to keep tags on a video and eventually want to be able to extract the tagged parts of the video to a new file. In a video that is 2 hours long I might want to extract say 50 10-15 second "clips" up to 15 times (event tagging). This will be for a free application.
I've found it brilliant (and easy) to render / seek / play clips, etc on XP-Win7 with no issues. I've "discovered" the joys of GraphEdit, creating graphs, the issues with COM in VB.NET, GMFBridge, ....etc.
Now I need some advice. Am I using the right technology. Directshow seems to be very resistant to the idea of "open video", "seek to clip", "write clip to file", .....repeat for all clips, close file. I can sort of do this already if I visibly render the video but would need to do it as a background task faster than realtime render speed.
Things that seem to be missing are:
- an example of anyone doing anything similar (export multiple clips to a single file)
- no easily available 64bit compressors (lots of 32bit stuff around)
- all the references and examples I do find are VERY old
- VB.NET is not the first "port of call" for DirectShow developers
So, the question is, should I be using something else?
If not, has anyone done anything similar before. I'm not looking for their code, I just want some guidelines as it takes ages to figure things out in DirectShow and VB.Net just using trial & error (and Google).
I've looked at AFORGE (no sound), FFMPEG (command line toolset), Media Foundation (reluctant to throw away XP) and a variety of commercial helper libraries but not really getting any further.
Apologies for the length but I wanted readers to understand the background.
All help appreciated.
To output clips to a single file Microsoft had created the "DirectShow Editing Services". Sometimes it works, sometimes not. We use it in our software to create videos from clips like you. With a little bit work you can also include effects to the video.
It is also possible to use AviSynth. It's a scripting system and frameserver for DirectShow.
As I know, with MediaFoundation you can also create a video from multiple clips, but I never tried this.
I'm trying to use to SketchUp API to navigate around 3D models (zoom, pan, rotate, etc). My ultimate aim is to integrate it with a Leap Motion app.
However, right now I think my first step would be to figure out how to control the basic navigation gestures via the Sketchup API. After a bit of research, I see that there are the 'Camera' and the 'Animation' interfaces, but I think they would be more suited to 'hardcoded' paths and motions within the script.
Therefore I was wondering - does anyone know how I can write a plugin that is able to accept inputs from another program (my eventual Leap Motion App in this case) and translate it into specific navigation commands using the Sketchup API (like pan, zoom, etc). Can this be done using the 'Camera' and the 'Animation' interfaces (in some sort of step increments), or are there other interfaces I should be looking at.
As usual, and examples would be most helpful.
Thanks!
View, Camera and the Animation class is what you are looking for. Maybe you don't even need the Animation class, you might just be ok with using the time in the UI class. Depends on the details of what you will be doing.
You can set the camera directly like so:
Sketchup.active_model.active_view.camera.set(ORIGIN, Z_AXIS, Y_AXIS)
or you can use View.camera= which also accept a transition time argument if you find that useful.
For bridging input you could always create a Ruby C Extension that takes care of the communication between the applications. There are some quirks in getting C Extensions work for SketchUp Ruby as oppose to regular Ruby though - depending on how you compile it.
I wrote a hello world example a couple of years ago: https://bitbucket.org/thomthom/sketchup-ruby-c-extension
Though note that I have since found a better solution for Windows, using the Development Kit from Ruby Installers: http://rubyinstaller.org/
This answer is related to my comment above regarding the view seemingly 'jumping' when I assign a new camera to the current view using camera=, but not if I use camera.set.
I figured out this was happening because the camera FOV for the original camera was different, and the new camera was defaulting to an FOV of 30. By explicitly creating the camera with the optional perspective and FOV arguments from the initial camera solves this problem:
new_camera = Sketchup::Camera.new new_eye, new_target, curr_camera.up, curr_camera.perspective?, curr_camera.fov
Hope people find this useful!
I'm fairly new to programming and I've been presented with fairly daunting assignment at work. I need to build a program from scratch in order to take advantage of the Kinect's motion tracking capabilities to interface with another application.
Some context:
Someone else I work with has built the test program- a console app using OpenGL. The test program consists of a cube inside of a skymap. The camera looks at the small cube, and can be rotated around the cube to view it from different perspectives
Someone else was able to use the sample codes in the developer toolkit to control the test program. The test program now works with motion tracking (swiping your hand to the side rotates the cube; moving your head side to side changes the camera angle so it looks like you are looking around a floating 3D object; walking forward or backward zooms the camera). It works as it is, but...
The problem is this: Now that we know it all works, it's time to simplify everything so that we can run the test program on a tablet. So the code needs to be stripped down to the bare bones. We need to remove everything from the SkeletalViewer code except for the elements that gather and process the data, so that it can be used in another program.
I've been asked to build a console app from scratch (rather than tearing apart the sample code-as this is extremely messy) that allows us to use the Kinect with our test program.
I've spent the last few weeks trying to figure out the code and I'm feeling overwhelmed! I don't know where to start.
Here's my question: what are the absolute bare essential building blocks in the Kinect program? I do not need it to draw ANYTHING. I just need a console app that, when running, gathers the motion tracking data and sends it to the other program.
I would greatly appreciate any guidance you can provide.
Thank you in advance!!!

You don't need to draw anything, but there's a need to create an event for caching the frames in order to work one them.
Here's pretty cool description of skeletal joints: MSDN - Kinect
Another thing I can give you is the main page of Kinect project. Here are the libraries, guides, code samples etc. You can download and install Kinect Toolkit, there are several programs inside (binaries + code samples) - everything you need to learn Kinect API: Kinect For Windows - Downloads and Kinect For Windows - Learn
I am developing a desktop application for Windows that will constantly show the map moving as a vehicle moves, getting the location from a GPS unit. I have written a quick little demo that accomplishes this, however it constantly flickers. I need to implement a solution that has a nice smooth movement. I have several things in mind that will hopefully resolve this.
First I think it would be better to create the map at around 2 to 3 times the size of the visible window and move the window over the map. When the window gets close to a side a new map is built in the background which replaces the current map. I'm still working on how to do that. (Hints welcome!! lol)
I think it would be a big step forward and the ultimate solution to turn on hardware acceleration for the application. Based on what I have read in the forums JOGL is the only practical way to add hardware acceleration to a Java desktop application. So here I am.
Has anyone toyed around with adding JOGL to GeoTools. I'm not talking about 3D at the moment, just making the display more efficient. It looks like it's going to be a big job implementing this change as it appears that it will affect almost all of the code from JMapPane on down. Any suggestions, code examples and hints will be greatly appreciated!!!
You may use the GLG2D project to render a Swing JComponent such as the JMapPane using hardware accelerated using JogAmp JOGL 2. This will allow you to use hardware acceleration with minimal changes to the GeoTools source.
http://brandonborkholder.github.io/glg2d/
JComponent renderPane = new JMapPane(...
JFrame frame = new JFrame("My GeoTools application");
frame.setContentPane(new GLG2DCanvas(renderPane));

When you run an Adobe product in a trial, a window appears each time asking if you have have a serial number yet or if you would like to continue with the trial. Next to that is a lovely 'number ticker', like the ones they used to have at airports (see image).
Does anyone know where I can get one of these, preferably gratis, to use as a component in a flex application?
As promised an version of the flip clock, ready to use on github free of charge. If anyone has request. By all means - ask.
https://github.com/StrangeMother/Flash-AS3-Flip-Clock-display
edit: Sorry aboutt he broken link. Some how the .git at the end of the URL buggered.
I made an app that uses such a feature. Download the air app and take a look. Its just a super simple poker game timer, but it has the feature you require.
if you like it, then I'll sift the code out.
http://pokerblind.strangemother.com/app/data/application/versions/0.1/air/PokerBlind.air
Its a heady mixture of OOP class code and front end. The numerals are a Numeric item in the library of which are managed by a timer class and number counting class. Extendable enough and the graphics should be easy enough to rip apart.
A while back I started working on a component like this. It's not super sexy yet. Check out the code on github:
https://github.com/jamesward/FlipClock
There are a few decent components available for close to free that I've found at activeden.net. They generally include source code so you can change them to meet your exact need. Here's a good example of what you can find there: http://activeden.net/item/flip-numbers/104628
Hope that helps.
A very good looking component can be found here:
http://www.flashcomponents.net/component/sense_flip_clock_3d.html
It does cost 8$, though. :)
