Passing a Projection Matrix to Renderer

[sipickles]

Hi,

I wonder if CEGUI could accept a VIEW/PROJECTION matrix supplied by the user?

This would all the entire GUI, or perhaps subsets to be drawn on different planes.

Code: Select all

// draw GUI on default screenplane
CEGUI::System::getSingleton().renderGUI();

// draw GUI on rotated plane
CEGUI::System::getSingleton().renderGUI( myRotationMatrix );


This could even be applied to different parts of the GUI

Code: Select all

//Start render loop

System::getSingleton().setGUISheet( statusWindow );
// draw status GUI on rotated plane
CEGUI::System::getSingleton().renderGUI( myRotationMatrix );

System::getSingleton().setGUISheet( mapWindow );
// draw map GUI on a different rotated plane
CEGUI::System::getSingleton().renderGUI( myOtherRotationMatrix );

//Stop render loop

Is this possible?

Hi,

This is not possible out of the box in current versions; future releases will make such things much easier as it will be possible to hook directly into the rendering of UI components at a certain level (though not necessarily in a api/engine agnostic manner).

Fair enough.

I look forward to it. That would make some interesting GUIs possible - think Compiz-desktop-cube

That kind of thing will be extremely simple with the new rendering model, since windows at a certain level will fully support rotation out of the box

This is actually possible already, at least in DX (my only area of mild expertise).

Render the GUI to a texture, then render the texture in 3d space....

This is what I am planning, at least until the new renderer model is released.
