Detailed Description¶
This node inserts a
glBlitFrameBuffer
or an equivalent into the command stream. This provides a more efficient method for copying rectangles between textures or surface backbuffers wrapped byQRenderTarget
than drawing textured quads. It also supports scaling with the specified interpolation method.Note
In practice the
QBlitFramebuffer
node will often be used in combination withQNoDraw
since a blit should not involve issuing draw calls for any entities.
- class PySide2.Qt3DRender.Qt3DRender.QBlitFramebuffer([parent=None])¶
- param parent:
Constructs a new
QBlitFramebuffer
with the givenparent
.
- PySide2.Qt3DRender.Qt3DRender.QBlitFramebuffer.InterpolationMethod¶
Specifies the interpolation applied if the image is stretched.
Constant
Description
Qt3DRender.QBlitFramebuffer.Nearest
Nearest-neighbor interpolation.
Qt3DRender.QBlitFramebuffer.Linear
Linear interpolation.
- PySide2.Qt3DRender.Qt3DRender.QBlitFramebuffer.destination()¶
- Return type:
Specifies the destination render target. When not set, the destination is assumed to be the default framebuffer (i.e. the backbuffer of the current surface), if there is one.
Note
the source and destination must not refer to the same render target.
- PySide2.Qt3DRender.Qt3DRender.QBlitFramebuffer.destinationAttachmentPoint()¶
- Return type:
Specifies the target attachment point.
- PySide2.Qt3DRender.Qt3DRender.QBlitFramebuffer.destinationAttachmentPointChanged()¶
- PySide2.Qt3DRender.Qt3DRender.QBlitFramebuffer.destinationChanged()¶
- PySide2.Qt3DRender.Qt3DRender.QBlitFramebuffer.destinationRect()¶
- Return type:
Specifies the destination rectangle. The coordinates are assumed to follow the normal Qt coordinate system, meaning Y runs from top to bottom.
- PySide2.Qt3DRender.Qt3DRender.QBlitFramebuffer.destinationRectChanged()¶
- PySide2.Qt3DRender.Qt3DRender.QBlitFramebuffer.interpolationMethod()¶
- Return type:
- PySide2.Qt3DRender.Qt3DRender.QBlitFramebuffer.interpolationMethodChanged()¶
- PySide2.Qt3DRender.Qt3DRender.QBlitFramebuffer.setDestination(destination)¶
- Parameters:
destination –
PySide2.Qt3DRender.Qt3DRender.QRenderTarget
Specifies the destination render target. When not set, the destination is assumed to be the default framebuffer (i.e. the backbuffer of the current surface), if there is one.
Note
the source and destination must not refer to the same render target.
- PySide2.Qt3DRender.Qt3DRender.QBlitFramebuffer.setDestinationAttachmentPoint(destinationAttachmentPoint)¶
- Parameters:
destinationAttachmentPoint –
AttachmentPoint
Specifies the target attachment point.
- PySide2.Qt3DRender.Qt3DRender.QBlitFramebuffer.setDestinationRect(destinationRect)¶
- Parameters:
destinationRect –
PySide2.QtCore.QRectF
Specifies the destination rectangle. The coordinates are assumed to follow the normal Qt coordinate system, meaning Y runs from top to bottom.
- PySide2.Qt3DRender.Qt3DRender.QBlitFramebuffer.setInterpolationMethod(interpolationMethod)¶
- Parameters:
interpolationMethod –
InterpolationMethod
- PySide2.Qt3DRender.Qt3DRender.QBlitFramebuffer.setSource(source)¶
- Parameters:
Specifies the source render target. When not set, the source is assumed to be the default framebuffer (i.e. the backbuffer of the current surface), if there is one.
Note
the source and destination must not refer to the same render target.
- PySide2.Qt3DRender.Qt3DRender.QBlitFramebuffer.setSourceAttachmentPoint(sourceAttachmentPoint)¶
- Parameters:
sourceAttachmentPoint –
AttachmentPoint
Specifies the source attachment point.
- PySide2.Qt3DRender.Qt3DRender.QBlitFramebuffer.setSourceRect(sourceRect)¶
- Parameters:
sourceRect –
PySide2.QtCore.QRectF
Specifies the source rectangle. The coordinates are assumed to follow the normal Qt coordinate system, meaning Y runs from top to bottom.
- PySide2.Qt3DRender.Qt3DRender.QBlitFramebuffer.source()¶
- Return type:
Specifies the source render target. When not set, the source is assumed to be the default framebuffer (i.e. the backbuffer of the current surface), if there is one.
Note
the source and destination must not refer to the same render target.
- PySide2.Qt3DRender.Qt3DRender.QBlitFramebuffer.sourceAttachmentPoint()¶
- Return type:
Specifies the source attachment point.
- PySide2.Qt3DRender.Qt3DRender.QBlitFramebuffer.sourceAttachmentPointChanged()¶
- PySide2.Qt3DRender.Qt3DRender.QBlitFramebuffer.sourceChanged()¶
- PySide2.Qt3DRender.Qt3DRender.QBlitFramebuffer.sourceRect()¶
- Return type:
Specifies the source rectangle. The coordinates are assumed to follow the normal Qt coordinate system, meaning Y runs from top to bottom.
