GLM and C GLM should probably be mentioned as well since you'll probably want a good linear algebra library if you are going with just a rendering library instead of a full game engine. As for physics there's tons of options, but the list gets rather exhaustive when considering 2D and 3D but you have box2d , bullet, and many many more.

Our great sponsors. Panda3D 18 3, 9. Confirm and generate the makefiles. Have a look into the target directory and if you like, do make and make install now but you may have to do this again and again during the next few recipes.
The following table will provide more details about creating OSG makefiles or solutions using different generators:. Most of them can read specified file formats mainly models and images into scene objects, and some can also write the nodes or images back to files. In this recipe, we are going to configure CMake options to build with the most common plugins. It is impossible to get all the plugins built under a certain platform.
But we still have some very common plugins depending on external libraries. To avoid missing them, there are two rules to follow: First, download or compile the development packages of external libraries; then, set related options while configuring OSG with CMake. We will first make a list of the most practical plugins, download their dependent libraries, and set them up in the cmake-gui window. The list includes curl, freetype, gif, jpeg, png, Qt , and zlib plugins.
Have a look at the book "OpenSceneGraph 3. Download all the binary packages of external dependencies with the apt-get command:.
Now it's time to configure these libraries using cmake-gui. Just reopen the GUI window and click on the Configure button. CMake has already queried these installed libraries and got them ready for compiling corresponding plugins.
Generate makefiles, and enjoy the compiling work again. It will take much shorter time to finish the entire process this time, unless you remove the build directory containing all the intermediate object files.
Let us see what these plugins do and where to learn about their dependencies:. It requires libCURL as the dependence. Don't miss it as we will talk about some interesting implementations about Qt and OSG in the following chapters. For Windows users, it may not be simple to get all these dependencies at once.
And to compile them from source code one-by-one is a really harrowing experience for some people but for somebody else, it may be exciting. Tastes differ! CMake may not work like a charm under Windows systems, that is, it can hardly find installed libraries automatically. Also, you can refer to Chapter 10 of the "OpenSceneGraph 3. You must be familiar with the compilation of OSG under Unix-like systems by simply inputting the following commands in a terminal:. Of course, the prerequisite is that you must have already configured OSG with cmake-gui or some other command-line tools and generated the makefiles as well.
If not, then you may first read the book "OpenSceneGraph 3. For Windows and Mac OS X users, we always have some slightly different ways to do this because of the wide use of IDEs Integrated Development Environment , but we may also build from makefiles by specifying the generator type in the CMake configuration window. Another interesting topic here is the packaging of built binaries. Set the environment variable PATH to include the location of the executables, and CPack will automatically find and make use of each of them.
Corresponding software must be installed to ensure the package generator works. After that, there is nothing besides make to build OSG libraries. Open a terminal and type make in the build folder to compile the OSG library, or use the generated solution file if you are using Visual Studio products.
But instead of installing to a specific directory, this time you could make a series of. Just type the following:. Windows users may open the generated Visual Studio solution. This will result in a series of zipped files or NSIS installers. Generated packages may differ as the result of changing CMake options. The prefix for example, openscenegraph-all It is really exciting to know that the latest OSG supports some of the most popular mobile platforms.
After preparing necessary environments and changing some CMake options, we can then easily build OSG for iOS and Android systems, including iPhone, iPad, most Android based devices, and their simulators. And there are also various API redefinitions and limitations that will make some functionalities work improperly.
So it will be an excellent example for demonstrating how to compile and use OSG on mobile devices. Remember that you need NDK r4 or a later version to make the compilation successful. However, the SDK version doesn't matter most of the time. Start cmake-gui and reset the options in the group OSG as shown in the table:. The parent directory of EGL. The libEGL library. Nearly done! That is because all of them have to be rebuilt with the Android compiler first, and there may be several limitations and errors.
We are not going to discuss this painful process in this book. Follow the discussions on "osg-users" mailing list and try to work out the compilation yourselves. Dynamic libraries or shared libraries allow many programs to use the same library at the same time, but static ones don't.
By default, OSG generates dynamic libraries such as libosg. The executable only record required routines in a library and all actual modules will be loaded at runtime.
This enables multiple executables to make use of only one library, rather than compiling the library code into each program. But it also brings disadvantages such as dependency and distribution problems. With static linking, target executables will include every referenced part of external libraries and object files at compile time, and there will be no extra shared files. This ensures that all the dependencies are loaded with the correct version. You may not be bothered by the installation of your applications again, as end users won't complain that a DLL file not found error is not displayed while using static-linked executables.
Of course, static libraries always make the result a larger size. Fortunately, OSG provides both static and dynamic linking options. It's up to the developers to decide which would win in their case. Start the cmake-gui utility. Now we are going to configure the build system to generate static or dynamic version of OSG libraries. Be careful; each time you switch between static and dynamic , the whole project including libraries, plugins, and applications will be rebuilt. So it is clever to make a static-build and a dynamic-build directory separately, if you want to update both configurations.
It is actually very easy to build static-link version of OSG libraries. We will assume you have already had a static-build directory for the building process.
Unmark them and confirm your changes. After the files are installed, go to the specified path and see what you have now. You will find that there are no. This is what we have just described before—static linking doesn't require extra shared objects any more. All modules referred to by the executable will be directly included at compiling time. While using static-linked plugins for programming, you must add corresponding file to the dependence list, and declare them in the global scope of the source code, which forces the compiler to look for modules in external dependencies.
The first two can register native OSG and OSGB formats into your executable, and the last will specify the right windowing system to use. Without dynamic loading of files and dynamic allocating of global proxy variables, OSG wasn't able to automatically check for them this time. Before we start discussing this recipe, open the following link and have a look at it:. Some of you may say: "Oh, this is a wonderful reference guide for me during the programming work.
It's impossible to keep all the classes in mind, and it's really rough to search for one method or function in the vast source directory. I'd love to have such a handy API document. But how did you make it, and how do you keep it fresh? The download link is:. It can draw some types of hierarchical graphs and thus makes life more colorful.
The toolkit can be found at:. Ubuntu users can install these two utilities with the apt-get command directly by running the following two command lines:.
Lastly, Windows users may choose to compile a CHM file. If you don't have one, download it at:. Start the cmake-gui window. Star 8. Updated Aug 23, C. Star 7. F1 Telemetry Collector and Viewer. Updated Nov 26, Python.
