A Qt3DRender::QClearBuffers FrameGraph node enables clearing of the specific render target buffers with specific values.
This enum type describes types of buffer to be cleared.
| Constant | Value | Description |
|---|---|---|
Qt3DRender::QClearBuffers::None |
0 |
No buffers will be cleared |
Qt3DRender::QClearBuffers::ColorBuffer |
(1 << 0) |
Clear color buffers |
Qt3DRender::QClearBuffers::DepthBuffer |
(1 << 1) |
Clear depth buffer |
Qt3DRender::QClearBuffers::StencilBuffer |
(1 << 2) |
Clear stencil buffer |
Qt3DRender::QClearBuffers::DepthStencilBuffer |
DepthBuffer | StencilBuffer |
Clear depth and stencil buffers |
Qt3DRender::QClearBuffers::ColorDepthBuffer |
ColorBuffer | DepthBuffer |
Clear color and depth buffers |
Qt3DRender::QClearBuffers::ColorDepthStencilBuffer |
ColorBuffer | DepthStencilBuffer |
Clear color, depth and stencil buffers |
Qt3DRender::QClearBuffers::AllBuffers |
0xFFFFFFFF |
Clear all buffers |
The BufferTypeFlags type is a typedef for QFlags<BufferType>. It stores an OR combination of BufferType values.
Specifies the buffer type to be used.
Access functions:
| Qt3DRender::QClearBuffers::BufferType | buffers() const |
| void | setBuffers(Qt3DRender::QClearBuffers::BufferType buffers) |
Notifier signal:
| void | buffersChanged(Qt3DRender::QClearBuffers::BufferType buffers) |
Specifies the clear color to be used.
Access functions:
| QColor | clearColor() const |
| void | setClearColor(const QColor &color) |
Notifier signal:
| void | clearColorChanged(const QColor &color) |
Specifies the clear depth value to be used.
Access functions:
| float | clearDepthValue() const |
| void | setClearDepthValue(float clearDepthValue) |
Notifier signal:
| void | clearDepthValueChanged(float clearDepthValue) |
Specifies the stencil value to be used.
Access functions:
| int | clearStencilValue() const |
| void | setClearStencilValue(int clearStencilValue) |
Notifier signal:
| void | clearStencilValueChanged(int clearStencilValue) |
Specifies a specific color buffer to clear. If set to NULL (default), and ColorBuffer flag is set, all color buffers will be cleared.
Access functions:
| Qt3DRender::QRenderTargetOutput * | colorBuffer() const |
| void | setColorBuffer(Qt3DRender::QRenderTargetOutput *buffer) |
Notifier signal:
| void | colorBufferChanged(Qt3DRender::QRenderTargetOutput *buffer) |
The constructor creates an instance with the specified parent.
