public class RandomTileRenderer extends TileRendererBase
TileRenderer w/o using fixed tiles but arbitrary rectangular regions.
See TileRendererBase for details.

RandomTileRenderer()
Creates a new TileRenderer object
|
| Modifier and Type | Method and Description |
|---|---|
void |
beginTile(GL gl)
Begins rendering a tile.
|
void |
display(int tX,
int tY,
int tWidth,
int tHeight)
Rendering one tile, by simply calling
GLAutoDrawable.display(). |
void |
endTile(GL gl)
Must be called after rendering the scene,
see
TileRendererBase.beginTile(GL). |
boolean |
eot()
Returns true if end of tiling has been reached, otherwise false.
|
int |
getParam(int pname)
Gets the parameters of this TileRenderer object
|
boolean |
isSetup()
Returns true if this instance is setup properly, i.e.
|
void |
reset()
Method resets implementation's internal state to start of tiling
as required for
TileRendererBase.beginTile(GL) if end of tiling has been reached. |
void |
setTileRect(int tX,
int tY,
int tWidth,
int tHeight)
Set the tile rectangle for the subsequent rendering calls.

end of tiling criteria is implementation specific and may never be reached.
User needs to TileRendererBase.reset() tiling after reaching end of tiling
before calling TileRendererBase.beginTile(GL) again.
end of tiling is never reached w/ RandomRileRenderer,
i.e. method always returns false.
eot in class TileRendererBasepublic final void reset()
TileRendererBase.beginTile(GL) if end of tiling has been reached.
Implementation is a nop where end of tiling is never reached.

This method modifies the viewport, see below.
User shall reset the viewport when finishing all tile rendering,
i.e. after very last call of TileRendererBase.endTile(GL)!
The PMV Matrix must be reshaped after this call using:
current tile's x-poscurrent tile's y-posfinal image widthfinal image height
Use shall render the scene afterwards, concluded with a call to
this renderer TileRendererBase.endTile(GL).
User has to comply with the GL profile requirement.
If end of tiling has been reached,
user needs to TileRendererBase.reset() tiling before calling this method.

Please consider TileRendererBase.reqPreSwapBuffers(GLCapabilitiesImmutable) to determine
whether you need to perform swap-buffers before or after
calling this method!
