    • PingPongBuffer

      public PingPongBuffer(int width, int height, com.badlogic.gdx.graphics.Pixmap.Format pixmapFormat, boolean hasDepth, boolean hasVelocity, boolean hasNormal, boolean hasReflectionMask, boolean preventFloatBuffer)
      Creates a new ping-pong buffer and owns the resources.

    • PingPongBuffer

      public PingPongBuffer(GaiaSkyFrameBuffer buffer1, GaiaSkyFrameBuffer buffer2)
      Creates a new ping-pong buffer with the given buffers.

  • Method Details

    • createMainFrameBuffer

      public static GaiaSkyFrameBuffer createMainFrameBuffer(int width, int height, boolean hasDepth, boolean hasVelocity, boolean hasNormal, boolean hasReflectionMask, com.badlogic.gdx.graphics.Pixmap.Format frameBufferFormat, boolean preventFloatBuffer)

    • set

      public 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.

      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 buffer
      buffer2 - 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 interface com.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 to capture()

    • getSouceTexture

      public com.badlogic.gdx.graphics.Texture getSouceTexture()
      Returns:
      the source texture of the current ping-pong chain.

    • getSourceBuffer

      public GaiaSkyFrameBuffer getSourceBuffer()
      Returns:
      the source buffer of the current ping-pong chain.

    • getResultTexture

      public com.badlogic.gdx.graphics.Texture getResultTexture()
      Returns:
      the result's texture of the latest capture().

    • getResultBuffer

      public GaiaSkyFrameBuffer getResultBuffer()
      Returns:
      Returns the result's buffer of the latest capture().

    • getMainBuffer

      public GaiaSkyFrameBuffer getMainBuffer()

    • getDepthTexture

      public com.badlogic.gdx.graphics.Texture getDepthTexture()
      Returns:
      the depth texture attachment containing the depth buffer
