right now i am looking into text rendering. after some research i found several ways to put text onto screen:
1) texture blitting as the way jpct examples do
2) billboard object3D placed in front of camera
3) using overlay class of jpct
4) make rectangles to hold texture of each character and render these rectangles with ortho projection and depth-test off

i would like to know whether blitting is the fastest method (runtime performance) and whether the 4th method can be done in jpct - i need to manipulate opengl states manually such as calling glDisable, glMatrixMode at a specific time in the rendering process.

hello i just started to try jpct the desktop version. so far i created a non fullscreen window with non standard size , but can't get OPENGL hardward renderer.
another problem is, if i set the window size to a standard size, the OPENGL renderer opens another window that i don't want.
how to setup the window correctly?

my current code is like this:

GraphicsEnvironment e=GraphicsEnvironment.getLocalGraphicsEnvironment();
gDevice=e.getDefaultScreenDevice(); GraphicsConfiguration gc=gDevice.getDefaultConfiguration();
gwin=new Frame(gc); gwin.setUndecorated(true); gwin.setIgnoreRepaint(true); gwin.setResizable(false);
gwin.pack(); Dimension d=new Dimension(1280,766); gwin.setSize(d);
gwin.setVisible(true); gfx=gwin.getGraphics();
gbuf=new FrameBuffer(1280,766,FrameBuffer.SAMPLINGMODE_NORMAL);
gbuf.enableRenderer(IRenderer.RENDERER_OPENGL); gbuf.optimizeBufferAccess();

and in the mainloop:
gbuf.clear(); gbuf.update(); gbuf.display(gfx);

note that i want the window to have no border/title, and sized 1280x766 (766=800-34, the height of taskbar)
in my experience at other 3D engine, non standard window size is achievable.
i am new to java and jpct, so can't find out what's wrong in my code. could someone help me? thanks.
