Constructor Summary
ConstructorDescriptionPingPongBuffer
(int width, int height, com.badlogic.gdx.graphics.Pixmap.Format pixmapFormat, boolean hasDepth, boolean hasNormal, boolean hasReflectionMask, boolean preventFloatBuffer) Creates a new ping-pong buffer and owns the resources.PingPongBuffer
(GaiaSkyFrameBuffer buffer1, GaiaSkyFrameBuffer buffer2) Creates a new ping-pong buffer with the given buffers. -
Method Summary
Modifier and TypeMethodDescriptionvoid
begin()
Ensures the initial buffer state is always the same before starting ping-ponging.com.badlogic.gdx.graphics.Texture
capture()
Starts and/or continue ping-ponging, begin capturing on the next available buffer, returns the result of the previous call.static GaiaSkyFrameBuffer
createMainFrameBuffer
(int width, int height, boolean hasDepth, boolean hasNormal, boolean hasReflectionMask, com.badlogic.gdx.graphics.Pixmap.Format frameBufferFormat, boolean preventFloatBuffer) void
dispose()
Free the resources, if any.void
end()
Finishes ping-ponging, must always be called after a call tocapture()

com.badlogic.gdx.graphics.Texture
void
rebind()
When needed graphics memory could be invalidated so buffers should be rebuilt.void
reset()
Restore the previous buffers if the instance was owning resources.void
set
(GaiaSkyFrameBuffer buffer1, GaiaSkyFrameBuffer buffer2) An instance of this object can also be used to manipulate some other externally-allocated buffers, applying just the same ping-ponging behavior.

set
An instance of this object can also be used to manipulate some other externally-allocated buffers, applying just the same ping-ponging behavior.If this instance of the object was owning the resources, they will be preserved and will be restored by a
reset()
call.- Parameters:
buffer1
- the first bufferbuffer2
- the second buffer
-
reset
public void reset()Restore the previous buffers if the instance was owning resources. -
dispose
public void dispose()Free the resources, if any.- Specified by:
dispose
in interfacecom.badlogic.gdx.utils.Disposable
-
rebind
public void rebind()When needed graphics memory could be invalidated so buffers should be rebuilt. -
begin
public void begin()Ensures the initial buffer state is always the same before starting ping-ponging. -
capture
public com.badlogic.gdx.graphics.Texture capture()Starts and/or continue ping-ponging, begin capturing on the next available buffer, returns the result of the previous call.- Returns:
- the Texture containing the result.
-
end
public void end()Finishes ping-ponging, must always be called after a call tocapture()
