I'm currently developing an application that uses Irrlicht's 3D and GUI capabilities (version 1.4.1).
I'm having trouble implementing a top-view camera... I mean, I have the camera all set and use a billboard to flip and display a render-target texture (although it crashes when exiting the program, something related to free.c).
My problem is that the 2d map (the top-view...) is to be integrated in the GUI, so the camera should not transform the billboard.
I've though of translating the 2d position coordenates to 3d and translate the billboard but it didn't work.
So, is there a way to "lock" the billboard in front of the camera in a way that it looks like a (2D) GUI element?
Or if you have any alternative, I'll gladelly ear (read
P.S: In my previous implementation I used a IGUIImage to display the texture but this shown the map wrong (flipped).
Thanks in advance,
