acquireImageForSharingAsync

public Event acquireImageForSharingAsync(CommandQueue queue)

Description copied from class: Image

Aquires this image object for using. Only call this method if this image represents a shared object from OpenGL, created with e.g. Context.bindImage(com.jme3.texture.Image, com.jme3.texture.Texture.Type, int, com.jme3.opencl.MemoryAccess) or variations. This method must be called before the image is used. After the work is done, the image must be released by calling Image.releaseImageForSharingAsync(com.jme3.opencl.CommandQueue) so that OpenGL can use the image/texture/renderbuffer again.

Specified by:

acquireImageForSharingAsync in class Image

Parameters:

queue - the command queue

Returns:

the event object

acquireImageForSharingNoEvent

public void acquireImageForSharingNoEvent(CommandQueue queue)

Description copied from class: Image

Aquires this image object for using. Only call this method if this image represents a shared object from OpenGL, created with e.g. Context.bindImage(com.jme3.texture.Image, com.jme3.texture.Texture.Type, int, com.jme3.opencl.MemoryAccess) or variations. This method must be called before the image is used. After the work is done, the image must be released by calling Image.releaseImageForSharingAsync(com.jme3.opencl.CommandQueue) so that OpenGL can use the image/texture/renderbuffer again. The generated event object is directly released. This brings a performance improvement when the resource is e.g. directly used by a kernel afterwards on the same queue (this implicitly waits for this action). If you need the event, use Image.acquireImageForSharingAsync(com.jme3.opencl.CommandQueue).

Overrides:

acquireImageForSharingNoEvent in class Image

Parameters:

queue - the command queue

releaseImageForSharingAsync

public Event releaseImageForSharingAsync(CommandQueue queue)

Description copied from class: Image

Releases a shared image object. Call this method after the image object was acquired by Image.acquireImageForSharingAsync(com.jme3.opencl.CommandQueue) to hand the control back to OpenGL.

Specified by:

releaseImageForSharingAsync in class Image

Parameters:

queue - the command queue

Returns:

the event object

releaseImageForSharingNoEvent

public void releaseImageForSharingNoEvent(CommandQueue queue)

Description copied from class: Image

Releases a shared image object. Call this method after the image object was acquired by Image.acquireImageForSharingAsync(com.jme3.opencl.CommandQueue) to hand the control back to OpenGL. The generated event object is directly released, resulting in performance improvements.

Overrides:

releaseImageForSharingNoEvent in class Image

Parameters:

queue - the command queue
