In the last post, we have created a basic 3D demo application with Irrlicht, in which we put a stack of crates, and we topple them by shooting a cube or a sphere. In this post, we will try to create an on-screen control so that you can move around with it, like using a [...]
In the last post, we have built the Bullet Physics, Irrlicht and irrBullet libraries together to create a shared library for the Android platform. In this post, we are going to create a small demo 3D game for Android, using the libraries that we have built earlier. This demo is not really anything new, I [...]
Just got a new Android phone (a Samsung Vibrant) a month ago, so after flashing a new ROM and installing a bunch of applications, what would I want to do with the new phone? Well, I’d like to know if the phone is fast enough to play 3D games. From the hardware configuration point of [...]
Yesterday, I saw a young colleague struggle with C++ string, so I decided to take a look to see what was going on. He was more familiar with Java than with C++. He was creating a string, and it didn’t come out exactly the way he wanted. The code looked similar to the following: string [...]
Most modern computers have multiple cores, and even new multi-core processors are available for portable devices now. Yet, software are not taking advantage of them. Processors are sitting idle, doing nothing, most of the time. A lot of frameworks, libraries, language extensions, and even new programming languages, have been proposed to take advantage of the [...]
Ubuntu 10.04′s repository only has OpenCV 2.0, but if you want to use the 2.1 version, which was released in April, you would have to build it from source. Here’s a simple how-to. First, you need to install the following required packages to build OpenCV: libgtk2.0-dev libpng12-dev libjpeg62-dev libtiff4-dev zlib1g-dev libjasper-dev libavcodec-dev libdc1394-22-dev libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev [...]
The GCC Steering Committee has approved the use of C++ in GCC, according to this message. Although the reasons behind the decision were not clear, but it’s probably a decision to make GCC framework more modular, by leveraging the C++ features. As GCC has become the mother of compilers, this decision could have great benefits [...]
When you are debugging your code in NetBeans, sometimes, you would like to escalate the privilege of your program to do certain things that are not permitted as a normal user. You can certainly run the command as: sudo gdb <your program> But then, that’s not a very nice environment to work in. Otherwise, why [...]
After using Eclipse almost exclusively for Java programming in the last 7 years, and put up with its different problems, which seem to pile up over the years, I finally took a jump and installed NetBeans 6.8 to see how it’s doing recently. The event that triggered the switch was an upgrade from Ubuntu 9.10 [...]
