## com.threed.jpct
Class AWTGLRenderer

    java.lang.Object
      com.threed.jpct.GLBase
          com.threed.jpct.AWTGLRenderer

All Implemented Interfaces:
  IRenderer

Direct Known Subclasses:
  JOGLRenderer

public class AWTGLRenderer
extends com.threed.jpct.GLBase
implements IRenderer

This is the renderer to support hardware acceleration via OpenGL into a Canvas using the LWJGL. To be more precise, it renders into an AWTGLCanvas provided by LWJGL. Therefore, all rendering has to be done in the AWT event dispatch thread. jPCT itself doesn't care for this thread and works totally independant from it. To get them both together, this renderer does quite a lot of work to queue jPCT's rendering commands until the Canvas gets repainted. The consequence is, that a call to FrameBuffer.display(...) no longer renders the image when using this renderer but just signals the renderer that the queue is ready for rendering. The actual rendering of the queued commands is done, when the Canvas gets repainted.
When using this renderer, it's required to execute the render(...); draw(...);display(...)-sequence for each frame or in other words: It's not a good idea to leave out the display(...)-step for a frame, because that will cause the queue to overflow.
All available parameters in the Config-class for configuring this renderer are marked with the prefix "gl".

Method Detail

### getLock

    public java.lang.Object getLock()

### init

    public void init(int x,
                     int y,
                     int cbpp,
                     int zbpp,
                     int samples)

  Description copied from interface: `IRenderer`
  Initialize the renderer. This method is called by the FrameBuffer class and there should be no need to call it directly.

  Specified by:
    `init` in interface `IRenderer`
  Parameters:
    `x` - the width of the videomode/framebuffer
    `y` - the height of the videomode/framebuffer
    `cbpp` - the minimal colordepth
    `zbpp` - the minimal depthbuffer-depth
    `samples` - the number of samples to take when using multi sampling AA

### dispose

    public void dispose()

  Description copied from interface: `IRenderer`
  Disposes the renderer and all its resources if it's not used any longer. Will be called automatically if needed...there's no need to call it directly from inside an application.

  Specified by:
    `dispose` in interface `IRenderer`

### execute

    public void execute(int mode,
                        java.lang.Object[] params)

  Description copied from interface: `IRenderer`
  Executes the renderer specific function. As usual, there is no need to call this directly so the functions are not documented here.

  Specified by:
    `execute` in interface `IRenderer`
  Parameters:
    `mode` - the mode
    `params` - the parameters for this mode

### drawStrip

    public void drawStrip(VisList visList,
                          int ind,
                          int length,
                          FrameBuffer buffer,
                          World world)
