Graphics / how to draw UI over a 3d openGL space?

« on: May 31, 2012, 06:06:37 am »

Hello!

i have a project that uses opengl to show some 3d models, and you can navigate around them using a xbox 360 wireless controller

but i have no clue about how to make a 2d user interface that draws over the 3d space, i just want to show some labels and maybe some buttons...

the first thing i want to do is to create a label that says: "Loading model...", and then shows the model in 3d, but it will be nice to render the coordinates of the camera in a corner or something...

how to mix 2d context with my 3d project using SFML?

PS: i already read http://www.sfml-dev.org/tutorials/1.3/graphics-window.php, but i did not understood pretty well about mixing width opengl.
PS: after some googling, it seems like there is some GLUI libraries, but i dont know if SFML have a better way to do UI, show text, etc...
PS: sorry for my bad english

General / xbox 360 wireless issue

« on: May 21, 2012, 01:29:57 am »

Hello!

hello!, i am implementing a camera using opengl, and i want to control it using a box360 wireless controller

i am having an issue with AxisR using a xbox360 wirelles controller

some revelant code:

std::cout
        << "(AxisR) = ("
        << Input.GetJoystickAxis(0, sf::Joy::AxisR)
        << ")"
        << std::endl;

 

and this is the console output

Code: [Select]

...
(AxisR) = (0)
(AxisR) = (0)
(AxisR) = (0)
(AxisR) = (0)

that is not touching the controller, but when i sightly touch the R Axis (RT button) and then release, now the output is

Code: [Select]

...
(AxisR) = (-100)
(AxisR) = (-100)
(AxisR) = (-100)
(AxisR) = (-100)

is like, in first place, values are from [0,100], but when input is updated, jumps to [-100, 100], and this is causing some problems in my application

this is normal, or there's a way to make this work properly?

some information:

i am using sfml on ubuntu, instaled via repositories this way: sudo aptitude install libsfml-dev

if you need more code, i can share a public repo in github
