IDE OpenGL

[zergling]

Hi everyone,
I open this Thread because I would like to learn the OpenGl, but I do not know where and which IDE I should use :(
Can someone help me please?
Bye and Thanks

[Wybiral]

With OpenGL it doesn't matter what IDE you use. What language are you planning to use?

[zergling]

Hi,
I am going to use C++

Could you tell me also what packages should I install to work with opengl please?
Bye and thx :)

Note 6 , wxWidgets examples !
WxWidgets is a multi platform GUI toolkit: http://www.wxwidgets.org (http://www.wxwidgets.org/)

First, get the package wx2.8-examples
$ sudo apt-get install wx2.8-examples

The package puts the examples into /usr/share/doc/wx2.8-examples/examples/ directory. It's a compressed tar-ball which you have to unpack/untar.
( If you have the older 2.6 version then the directory is /usr/share/doc/wx2.6-examples/examples/ )

Run the "unpack_examples.sh" script (in the same directory) to unpack the samples in to your $HOME directory.
For example, run:
$ /usr/share/doc/wx2.8-examples/examples/unpack_examples.sh $HOME/wxwidgets2.8

And it will unpack & put the samples in to $HOME/wxwidgets2.8/samples/ folder.

You can compile and run the examples directly from the command line.
The compilaton requires wxWidgets' development headers and libraries. You will need packages: libwxbase2.8-dev wx2.8-headers libwxgtk2.8-dev

As an example let's compile the /popup sample code.
$ cd $HOME/wxwidgets2.8/samples/popup/

Compile the project.
$ make

Run it
$ ./popup
./ means the current directory. Yu must include it, otherwise the shell will not find the program, because by default, the current directory is NOT in the $PATH.
$ echo $PATH

Now, try to compile and run the other wxWidgets examples as well.

Study also the wxWidgets' documentation package wx2.8-doc.
$ apt-cache search wx2.8-doc
wx2.8-doc - wxWidgets Cross-platform C++ GUI toolkit (documentation)

Install it and list the documentation (html) files
$ dpkg -L wx2.8-doc
$ dpkg -L wx2.8-doc | grep index

Of course, the documentation is available online too... (http://www.wxwidgets.org/docs/)

+ read http://zetcode.com/tutorials/wxwidgetstutorial/

Note 7 , Necessary packages to develope SDL-applications.
SDL stands for Simple DirectMedia Layer... (http://en.wikipedia.org/wiki/Simple_DirectMedia_Layer)
It's a framework to greate portable 2D graphics applications. It also supports OpenGL.

First, list all packages that belong to the SDL family.
$ apt-cache search libsdl | grep dev
The "-dev" packages contain the header (include) files and dynamic libraries for app development. You'll need them.

Install at least these basic packages. These give you a good start.
$ sudo aptitude install libsdl1.2-dev libsdl-image1.2-dev libsdl-sound1.2-dev libsdl-mixer1.2-dev
However, the most basic apps need only "libsdl1.2-dev".

Then create a basic SDL-application via the Code::Blocks' project wizard (select SDL project).

Hi,
I am going to use C++

Could you tell me also what packages should I install to work with opengl please?
Bye and thx :)

SDL is a pretty good option for using OpenGL with C++, this will install OpenGL and SDL:


sudo apt-get install libgl1-mesa-dev libglu1-mesa-dev libsdl1.2-dev


That's all you'll need to build SDL+OpenGL applications. SDL also has a bunch of additional libraries for things like image loading, text rendering, networking, audio, etc. It's also really portable and commonly used.

[zergling]

Hi guys, I would like to ask you something:
What is the difference between opengl, glut and glfw?
Is glut in c++ and gflw in c? What about just opengl?

I installed the glfw but I do not know what to put when the codeblock ask me Please select a GLFW's location....

Thx a lot both of you :) I REALLY appreciated your help !

P.S. May I start porgramming in OpenGL after covering just the basics of C++ such as loops, functions and array?
Or, do I need more C++?

[moma]

Re-hello,

From the http://freeglut.sourceforge.net web page:

GLUT (and hence freeglut) framework let you Create and manage Windows containing OpenGL contexts on a wide range of platforms and also Read the mouse, Handle keyboard and joystick functions transparently.

So with freeglut, you can port your code to several platforms (Linux, Unix, Windows, Mac) and be sure that Keyboard, Mouse and the basic Window functions just work. But OpenGL is OpenGL no matter you use it from freeglut or from other frameworks. OpenGL is OpenGL and need to be learned.
----------------

Ref. your GLFW question.
This is howto install GLFW (it's not in the Ubuntu's package system).

$ wget http://prdownloads.sourceforge.net/glfw/glfw-2.6.tar.bz2
$ tar -xvjf glfw-2.6.tar.bz2
$ cd glfw

$ make x11

$ PREFIX=/usr sudo make x11-install

$ sudo ldconfig
--------

in the Code::Blocks GLFW's project wizard, say /usr when it asks GLFW's location.
Because libraries inhabit the /usr/lib directory and include files are in /usr/include/.


EDIT:
The example code that is generated by the GLFW's project wizard needs also link to "libxrandr.so" library.
It means that you must install the libxrandr-dev package.
$ sudo apt-get install libxrandr-dev

And in Code::Blocks, use the wizard to create the sample code, browse to the menu selection Project -> Build options.... and set the library under "Other link options"
See picture: http://bildr.no/thumb/115696.jpeg (http://bildr.no/view/115696)
--------

I recomend that you choose freeglut over GLFW because freeglut is more common, well known and tested library. Also supported by Ubuntu.
Both frameworks work well from C and C++.

Duplicate posting. How to delete this?

[hecato]

mmm, I remember that was on edit advanced... "Edit your post, then there is a option for delete it" but I not see it now.... perhaps no longer available... or I'm remembering another board.

But should be enough if you only write "duplicate posting", like you do it.

[Wybiral]

GLUT is similar to SDL in that they are both portable abstraction layers. They allow you to get a window up with OpenGL, without having to deal with the lower-level GUI code (making it more portable because the same code works on a variety of systems).

I will note that GLUT is more of a prototyping tool and will impose some restrictions on how you construct your program (it forces program flow to be managed by it). SDL has more features geared towards games and more extensive OpenGL programs (such as cross platform multi-threading and thread-safe event/message handling), and gives you more freedom over the design.

[zergling]

Ok, if you say that freeglut is the best choise, I trust you :)
Thx thx so much my friends, I do Really appreciated all your help.
Grazie Mille :)

[moma]

Sounds good.
Learn to program OpenGL with the freeglut framework.

Later, when you create bigger OpenGL applications (like SecondLife and similar ;-), then move to Panda 3D... (http://www.panda3d.org/), Allegro... (http://en.wikipedia.org/wiki/Allegro_library), SDL... (http://en.wikipedia.org/wiki/Simple_DirectMedia_Layer), Irrlicht... (http://en.wikipedia.org/wiki/Irrlicht_Engine), Ogre 3D... (http://en.wikipedia.org/wiki/OGRE_3D) or OSG... (http://www.openscenegraph.org)

EDIT: Compile panda3d on Ubuntu 8.04... (http://ubuntuforums.org/showthread.php?p=5522260#post5522260) (test)

OMG moma, I've never seen such a complete set of instructions on how to install / setup OpenGL on ubuntu before. I hope you don't mind, but I am going to reproduce these instructions on my website for other people needing this kind of help. http://www.glchronicles.mccolm.org

It should be enough.

You might want to learn about various data structures (stack, list, queue) since it would help you organize your data.

You might want to also read about and understand what a state machine is, since that is how OpenGL is organized.

I'm trying to install the stuff Moma mentioned but I'm getting this error:


alex@ubuntu:~$ sudo apt-get install libcodeblocks0 codeblocks libwxsmithlib0 codeblocks-contrib

Some packages could not be installed. This may mean that you have

The following information may help to resolve the situation:

I've already got libwxgtk2.8-0 installed, so I don't know what it's complaining about.

[slavik]

read the error carefully:

libcodeblocks0: Depends: libwxgtk2.8-0 (>= 2.8.6) but 2.8.4.0-0ubuntu3 is to be installed

libwxgtk2.8-0 is not new enough ...

What should I be installing then?

Hi, I just followed the Hardy Heron steps for installing Code::Blocks, freeglut, and wxwidgets. I tried compiling the sample and everything runs fine except for one small but annoying problem: The GLUT window is missing the title bar. It is actually there but it just doesn't show it meaning I can click a non-existant "x" and it will close the window. I tried compiling it using Code::Blocks and gcc using -lglut if that helps. Both do the same thing. Comparing what I see on my screen and the posted screenshot, the difference is the title bar obviously and the fact that I have a terminal type thing running which is what I think is wrong. Any help would be appreciated. Thanks in advance.

Sorry for the long post.

[fabianmejia]

I also suggest Code::Blocks, it's a great IDE and includes project wizards for Opengl, GLUT and SDL.

Please check a small howto:

I have installed the freeglut but when I started to build the glut project. I got the following error:
